Beryl is one of the oldest minerals known by mankind. The origin of the name might have originated from the Greek word for blueish gems "beryllos". The Latin word "beryllus" referred to lustre and clarity.
The French word "briller" ("shining" ) and also the German word for glasses, "Brille" come from the same Latin word.
Beryl is a beryllium cyclosilicate. It is an important mineral for the industry as well as for the gem and mineral specimen markets.
Beryls have been found in considerably large sizes, in Malakilina, Malagasy a18m by 3.5m crystal was found weighing 380 tons and a tapered crystal measuring 10,06m by 1,38m was recorded by Stevens (1972, p.50) as having been found in 1950 at the Bumpus Quarry, Albany, Oxford County, Maine, U.S.A. [David Von Bargen]
Beryl occurs in a variety of colour variations, below you will see a list of the different Beryl varieties and closely related minerals.
There's also Beryl that doesn't belong to either of the below mentioned colour varieties. Among them are more or less opaque crystals in different pale colours, these are usually named "common Beryl" or in German "Gemeiner Beryll". Some of them however come in crystals with nice colour and gem quality, like for instance the fantastic Finnish green Beryls (however these are sometimes referred to as being Heliodor) and the African "golden" Beryls that appeared on the gem and specimen market over the last decade.

If you click on the the names you'll be directed to the article dedicated to the specific variety. Bazzite and Pezzotaite are isostructural with Beryl (so are a couple of other minerals). But because of their importance in the gem and/or specimen market I thought it a good idea to include their links here.
This article will only include the "common Beryls"

Sinkankas reported gemmy aquamarine & golden beryl in small prismatic crystals from small vugs in a granitic pegmatite near El Mesquite village, about 27 km S of El Condor turnoff from Highway 2 (El Condor is ca. 49 km E of Tecate. The pegmatite occurs between Jassay and El Topo and is mineralogically simple, consisting largely of feldspar with some quartz, schorl, mica, rare purplish apatite, albite, and euhedral prisms of pale greenish yellow to pale golden-yellow beryl, ranging from acicular to some about 7 mm in diameter to 77mm long. Some are smooth-faced, others etched and tapered. Most contain abundant inclusions of extremely small size which render the bases opaque or only translucent but in a sharp transition: these disappear toward the terminations, the latter being transparent.

The Evje/Iveland district host several hundred small pegmatite quarries predominantly worked for quartz and feldspar. The area is known for good quality REE minerals and the rare scandium mineral thortveitite. Several quarries has also been worked for beryl, and in the years after WW2, beryl was the main product from a few quarries.

Beryl in these pegmatites occurs embedded in feldspar and quartz and are normally found as opaque greenish/yellowish crystals, although gem quality material are known. The Havåsen quarry has produced some very large crystals. Already in 1933 a crystal weighing around a metric ton was found, and in 1947 a 3,25m long crystal with a 1,3m diameter appeared. This is the biggest beryl crystal found in the area. Rosenquist (1949) describes how 5 crystals with a total weight exceeding 13 tons where extracted the winter 1947-48. Some of this material had " large transparent areas one could see far into", a 270kg piece was one of them. A deep blue aquamarine "leftover fragment" was cut into a 10ct faceted stone.

In 1967 a group of large crystals was found in the Beinmyr quarry. The largest crystal was 3,15 m x 42-54 cm weighing about 1,65 tons. Several other crystasl was found in this period and the book "Iveland 5, mining" contains interviews with former miners how they worked this mine: " We where working for feldspar and mica, and we had just sent away 1 1/2 truckload of muscovite when we suddenly hit a large beryl "nest". After a blast I could se the top cap of a beryl crystal in the wall, and we extracted a total of 3,5 tons from this nest. There where both large and small beryls. The biggest one where 300kgs, and I was able to save a 80kg single crystal with an intact end-cap..... Of other minerals we found columbite and monazite. The monazite was sparse but we found nice, large crystals to hand size. They had a wonderful colour and beautiful crystal development. They probably weighed a few kilograms each."

Large beryls has also been found later. In the 70-ties, Bjarne Engestøl found quite a lot of beryl at Knipane. The largest crystal exceeded 1m. This time, the gemmy material was secured and both stones with a deep yellow and rather deep aquamarine was cut.

Until 10 years ago, Arild Omestad spent a week a year working the Brattekleiv quarry for beryl specimens.This quarry is qute rich in beryl and the size of the crystals are more "cabinet friendly" than the the ton sized crystals.

Many of the crystals may contain gemmy areas, but gem material was not kept as such until the late 60-ties and later. The mining operations was then rapidly declining. Some collector gems has been made, and in particular Ivar Gautestad collected and faceted some material. He has amongst other prepared and sold a handful sets containing 9-12 faceted beryls in different colours from colourless through yellow, green and blue. [Olav Revheim]

California, San Diego Co., Pala District

Scale 1 Inch, rule 1cm©

The Pala district in northwestern San Diego County, California, has been a widely known source of gem and lithium minerals. Formal mining operations began in the 1870's, but the most active period was from 1900 to 1922. Several underground gemstone mining operations on Tourmaline Queen Mountain and Chief Mountain persist to this day.
The Pala district has been the subject of many science-and industry-based reports, focusing on gemology, mineralogy, petrology, physics and other facets relating to the 400 or so Rare Earth Element (REE) pegmatite dikes (outcrops, veins, ledges, bodies, deposits, lodes etc.).
The area is also often referred to as the Pala Gem Mining District, or the Pala Pegmatite District. It is a common misnomer that the term "district" is an official designation. The Pala area was never established as an organized mining district, and as such all mining claim documents pertaining to the statutes of the United States and California were filed with the Office of the County Clerk.

The Pala Band of Mission Indians, whose reservation was established for the benefit of the Cupeño and Luiseño Indians in 1891, had encompassed most of the mineral lands often referred to as the Pala District or Pala Mining District by 1903. By 1988, several Acts of Congress had appropriated all of the remaining public lands once open to mineral entry under the general mining laws for the benefit of the Mission Indians, excepting the federal mineral patents issued between 1913 and 1979 from the transfer.
Because of the significance of the Pala district's impact on San Diego's history and economy, the County's regional land use plan recognizes the importance of the gem mines in Pala, and generally encourages the immediate development of the eight federal mineral patents.

United States Mineral Patents granted in the Pala mining district by date issued:
1913 - Tourmaline King lode by F. B. Schuyler
1914 - Ed Fletcher Jr. lode by Ed Fletcher
1949 - Stewart Mine lode by Blanche C. Crane
1949 - Hiriart lode by George A. Ashley
1955 - Tourmaline Queen & Tourmaline Queen No. 3 lodes, Pala Chief lode, Goddess lode by Mildred S. Wear and Margaret S. Moore (Frank A. Salmons heirs)
1979 - Oceanview lode by Roland Reed

Pala, also referred to as the Pala Mission or Village of Pala, is the name of the town nearest to the gem-bearing pegmatite mines which are located in the nearby mountains to the north, east, and south. The town of Pala is not itself a specific mineral producing locality, except for a small-scale granite quarry which has operated for several decades on the west side of town. The mine produces gabbro and granodiorite riprap which is used locally along the roads for erosion control purposes.
The best known historical landmark in the town of Pala is the famous Mission San Antonio de Pala Asistencia campanile. Completed in 1818, the bell tower was rebuilt after collapsing during the floods of 1916. During the reconstruction of the original mission complex after the floods, several large pieces of deep purple lepidolite from the nearby Stewart mine were used in the surrounding courtyard walls as ornamental stone. The decorative lepidolite was donated by local gem miner and mineral dealer Frank A. Salmons, president and principal owner of the Pala Chief Mining Company. [Scott L. Ritchie]

California, San Diego Co., Warner Springs Co., Carmelita Mine

Crystals up to 2,4cm© Rob Lavinsky

The Carmelita mine is located in the SW¼ sec. 36, T9S, R3E, SBM, near the southeast end of the crest of a prominent northwest trending granite ridge in the SE4 and SW4 of Section 26, T9S, R3E, SBM; about 5 miles north of Warner Springs, San Diego County, California, USA.

Situated an elevation of 4800' AMSL, the exposure is covered with dense chaparral amidst small stands of Coulter pine. The primary development is in the center portion of a continuous northwestward striking pegmatite vein up to 400 feet across, that is at least 2000 feet long and has an average dip of 40° south.
The pegmatite is enclosed in granodiorite, which contains numerous septa and inclusions of platy, impure quartzite and mica-schist; and is thought to be underlain by gabbroic country rock.

History:
The mine was discovered on April 29th, 1907, by a local Basque prospector from Warner Springs named John Peter Labat (Jean Pierre Labat), as he was hiking atop the nameless but visibly prominent physiographic feature a few miles north of Warner's Ranch, investigating an area where several masses of milky-white quartz outcropped on the surface. Sunlight and a little digging soon revealed considerable quantities of pink, blue and green tourmaline.
The great gem discovery caused Labat to quickly locate a quartz (lode) mining claim on May 1st which he appropriately named "Carmelita", and recorded at the San Diego County Courthouse on May 7, 1907. The outside lines of the claim were located between the places of John Linton and the Old Web place or Larue Flat.

Around 1910, early Chihuahua Valley homesteader and local camp outfitter Ray Mitchell, came across Labat as he was riding down the trail towards Colonel Ed Fletcher's ranch. Mitchell said that "French Pete" showed him several large (5" x 3" ) nicely colored tourmalines from recent mining, and he was taking them down to San Diego for sale.

Available data for the years 1907 through 1915 indicates that the Carmelita was the leading producer of tourmaline within this remote mountainous region of northeastern San Diego County. Records disclose approximately 26 pounds of tourmaline recovered from surface and underground workings.

By June of 1932, the Carmelita claim title was transferred to "Jeanne Marie Frey" of 3117 - 28th Street, San Diego. At the request of Frey, the U.S. Department of Interior's General Land Office issued instructions on June 24th of 1932, to perform a Mineral Survey of the Carmelita Lode claim. The survey commenced on July 11th of that year, and was performed by R. Robinson Rowe, a licensed United States Mineral Surveyor, with the assistance of Eric V. Quartly who acted as the "Chainman", and "Assistant Transitman".

Together, in pursuance of instructions received from the Office of Cadastral Engineers at San Francisco and Glendale, California, Rowe and Quartly proceeded to mark the corners and survey the boundaries of the Carmelita Lode and the Carmelita Mill Site.

Rowe's survey reported the labor expended and improvements made upon the Carmelita Lode claim, which included detailed description of the character, extent, location, and itemized value thereof. The improvements at that time consisted of 14 cuts, 6 drifts, 2 stopes, 1 trench, 9 tunnels, and 1 winze.
Using Frey's inventory which was purchased from Labat years earlier, Rowe estimated the total improvement value at this time to be $5,690. His survey concluded that a total of approximately 681 short tons of pegmatite were removed and processed between 1907 and 1932, with an average gemstone recovery value of $8.36 per ton. Jeanne Marie Frey apparently died in 1935 prior to receiving a patent grant to the lode.

Around 1935, Chihuahua Valley resident Ottis Mitchell (10 years the younger brother of Ray Mitchell), accompanied neighbor and local hardrock miner A. N. Pearson (Andy Pearson) up to the "French Pete" mine to see a large gem-pocket that Pearson had recently discovered.
Mitchell, a mining engineer graduate from the local University of Riverside, described Labat's original pack-trail which had been roughly converted into a "two-track road" to facilitate travel from "stump to bolder" of Pearson's "old Dodge" truck.
He described Pearson's discovery as a "big pocket filled with large rose-colored tourmaline crystals encased in a bluish-green powdery clay". He also recalled that the reward was exceptional for Pearson, with many large gem-grade tourmalines being recovered, yet ultimately the work was very hard, and the gemstones proved "not easy to get". It was also noted that most of the work performed by Pearson usually did not involve contracted laborers.

On August 6, 1977, Roland Reed of El Cajon and George Ashley of Pala, relocated a lode mining claim on the Carmelita mine on the deposit, naming the claim after Weber's 1963 geographical description; the "Crest Gem".
Reed and Ashley soon began development at the mine by using a track-dozer to create an access roadway from Lost Valley Truck Trail (Lost Valley Road) to the north side of the summit upon which the gem-bearing pegmatite exposure and historic underground workings were located.
Within a few months, the duo engineered over 1 mile of new roadway constructed in rugged steep slope conditions, with a relatively dramatic elevation gain of over 480 feet to the top of the ridge. Work began to extend the lateral drifts on the southwest dip slope of the pegmatite, in hopes of encountering a continuation of pocket zones removed by Labat nearly 70 years earlier.
Approximately 60 linear feet of underground workings were constructed during this period, with only a few minor pockets encountered as a result of this work, primarily consisting of quartz crystals and microcline feldspar.

Giuseppe Laddomada of Vista began an intensive exploratory program in 1978, utilizing a small track-dozer, downhole drilling and hardrock blasting to expose additional sections of productive pegmatite.
Between 1978 and 1992, two large pockets nearly 20 feet long were discovered that produced many fine tourmalines in colors of green, blue, and pink. Additionally, many excellent beryl crystals were recovered, in both blue (aquamarine) and pink (morganite) varieties. In between these areas, large quantities of smoky quartz crystals were discovered, many of which exceeded 7 lbs in weight.
In March of 1993, Erik M. Cordova of Torrance discovered a large pocket containing over 100 quartz crystals, some weighing as much as 8 lbs, with many attached to an aesthetic matrix of cleavelandite and microcline feldspar.
During a field trip in May of 1998, Bureau of Land Management (BLM) Geologist, Walter 'Buzz' Todd - witnessed the discovery of several gem-quality morganites. These beryl crystals were light-pink with etched exteriors, the largest weighing just over 7 grams. In June, of that year, the San Diego Mining Company (SDMC) received concurrence with planned surface development and reclamation activities from the BLM, setting the stage for an intensive exploration program.

During the summer of 1999, a section of pegmatite was removed within the northwestern portion of an existing trench in which was an exposed underground lateral drift. In this zone was discovered a bright pink montmorillonite clay-filled pocket measuring approximately 2 feet across, which produced nearly 200 grams of fine quality green tourmaline crystals.
The largest of these elbaite crystals measured over 4 inches long, weighing 11 grams, and 45 percent of the prism consisted of flawless rough suitable for faceting a truly museum-quality gem. Additionally, over 200 lbs of carving-quality lepidolite was recovered, along with several unique specimens of cassiterite and fluorapatite on matrix, marking the end of a colorful century for the Carmelita lode.

Beginning in 2000, exploration work by SDMC had focused along the steep pegmatite exposures located along the north and south sides of the mountain. Amidst the high-rise pegmatite boulders and thick brush, continuous pick and shovel discoveries of blue tourmaline, pink beryl and yellow quartz gemstones were been made by the crew in preparation of the portal site for the underground emergency escapeway.[Scott L.

200 ton beryl from Brazil

A tapered beryl crystal 33 feet long (10.06 m) and 6 feet (1.83 m) in diameter was recorded by Stevens (1972, p.50) as having been found in 1950 at the Bumpus Quarry, Albany, Oxford County, Maine, U.S.A.

The crystal reported by Waldschmidt (1920) as being the largest known of beryl came from the Bob Ingersoll mine, South Dakota, U.S.A., and had a diameter of 1.17 m (46 in.) and a known length of 1.12 m (44 in.). (max length 5.4m another?)

Harjo,
It might be wise to give the source of some of the information in the text. Like in the text about the Carmelita none of us were alive in 1907 so where did this information come from. If you wrote it from your own experience the text should be followed by your name and current date in brackets. Nice job by the way. I like the idea of the links to the other beryl varieties.

Great work Harjo. Rather than ask you to caption the leading photos, I've done it myself. I hope that is OK:)
Edit: I now see why you didn't caption them. I was afraid it would screw with your nice placement of the photos and it did!!!
Edit: I put it back. The problem was that Aquamarine was too long, but I think there would be room for coloured numbers only in the captions and then take the nine go to names give them coloured numbers in the order of the photos and place them immediately below the 9 photos. I don't mean to make work. it is just an idea.
Edit: In 1987 I visited the Vienna Natual History museum and saw their red beyl labelled as Bixbite. I informed an English speaking security person that he should inform the curators that Bixbyite was black and the label should be changed. When I got home I discovered to my embarrassment that Bixbite is a synonym for this Utah red beryl.


The Tanco white beryls are Cs rich and should re investigated in the light of Pezzottaite. I've seen two such specimens and Ray Lasmanis has a third. I could have got the photoed specimen $4 grand, but declined due to the damage. It came from the Philadelphia collection and was donated by an important Canadian mineralogist. I forget whom, but the info is on the labels. All the Tanco material is frozen in matrix, so an undamaged xl would be very rare. Currently Cabot Corp., a US rare metal fabricator, owns Tanco and have just shut it down.

Hi Harjo,

The attribution for the Pala District and Carmelita mine text should be to me [Scott L. Ritchie], versus [Mindat]. Thanks for the inclusion of my mineral and locality data in your Best Minerals - Beryl article.

hi
we are gemstones hunter , and we are working in emerald mine, recently we discovered this stone wich looks like heliodor
but what it is very strange is this stones occurs in pegmetite fingers wich go through the mica-schiste as the emerald but the color is light-yellow green. Normaly the heliodor gains its color from iron but this mica-schist has chromium.
IS IT POSSIBLE THE EMERALD CAN BE OCCURED WITH THE HELIODOR.

This is a beryl in quartz I found on the flank of Black Mountain in Pinal County, Arizona (not the Black Mountains in Maricopa County). Not pretty at all, but representative of the beryl in the area. It is my understanding that beryl nearby was mined sometime in the past for the beryllium content.

Harjo,

I don't know if you saw the beryl uploaded as an attachment in the What's your favourite mineral specimen TODAY part four, Gail Style thread:

[www.mindat.org] by Jean-Luc DUBARE, but it is a wonderful green beryl from Madagascar and it might be good for your article if you could ask him to upload it to mindat.

Hello Harjo,

I believe the second specimen you have under the Urals heading is mis-located. The strong color banding at right angle to the C-axis is characteristic of beryls from the Audon-Chilon region (likely Sherlovaya Gora), Transbaikal. I have seen both blue and green crystals with this banding from this locality. The attached photo (crystal is 3.5 cm tall) is typical of the gem beryls found in the Alabashka region of the Central Urals. If you want a second opinion, I would suggest contacting Peter Lycberg. He is quite knowledgeable on Russian localities and has visited many of these places himself.

Cheers,
Jesse

Harjo:
While Montana isn't known for its beryls, this specimen was found in the Boulder Batholith near Butte, and is a very unusual occurence for this mineral:

Jesse and Harju

All (I am quite sure also Olegs but harder to see from photo, 99% sure) of the Russian beryls are from the greisen deposit of Sherlove Gora, NW Borzya, Chitinskaja Oblast, Transbaikal, Russia.
Yes, Jesse, this typical color bancing occurs in most of them. Adun Chelon is a pegmatite occurence some 20 km to the west.
I have collected at booth places and in fact had over 5000 small crystals myself from here and studied another few thousand.

Even in most Russian museums specimens from Sherlova Gora are misslabeled as from "Adun Chelon", Nertschinsk, etc.
Near Nertschinsk are several other gem pegmatites in the Borschovochny range, one of the main districts the Urulga.

Thanks all!!!

Jesse and Peter,
So, Peter, if I get it right Sherlove Gora is not a part of Adun Chelon, if so I'll change the locality for the Siberian Beryls to Sherlove Gora and will send a message to the owners of the photos. Peter, what do you think of the Alabashka Beryl from the Harvard collection that Jesse mentioned, Jesse has a point in that it looks a lot like a Sherlove Gora Beryl, or did these Beryls with the distinct colour zoning also occur in the Alabashka field?
p.s. Thanks for the great winter-Weardale-wonderland photo Jesse, I hope you and Joan had a good time over there!! And Peter, how's the cold in Siberia? I hope you can counter the effects with enough sauna visits!!

Chris,
Thanks a lot for the pointing out the Montana specimens. Fantastic inclusions. I'll put them in the article.

Rock,
I'll sen Jean-Luc a message, if he uploads the photos on Mindat I'm definitely going to add them to the article.

Dennis,
Thanks for sharing the Arizona locality.

SOMGEM,
Thanks, can you upload the photograph together with the locality to the Mindat database so I can add the locality and photo to the article?
About your question; it's not uncommon to have differently coloured Beryls in the same occurrence. Very often Emeralds coloured by Chromium have Iron in them too, I once found a piece with Emerald next to Aquamarine in Habach valley.

Keep it coming winking smiley

Cheers

Harjo

Tony, thats a nice little specimen. We will probably use it in the article. What can you tell us about the article and the heliodor crystals that came from there? When were they found? How big did/do they get? How many were found/
