7GE-5R3Baryte : BaSO4, Quartz : SiO2

Multiple photos available
Murray mine, Independence Mountains District, Elko Co., Nevada, USA

Dimensions: 8.7 cm x 7.3 cm x 4.3 cm

8.7 x 7.3 x 4.3 cm. A lovely specimen from the lesser known Murray Mine in Nevada. This piece features two generations of baryte, which are separated by a layer of sugary/drusy quartz. Both generations of baryte formed in pseudo-rhombic, thick, blocky crystals with soft silvery hue, with a deposition of sparkling white quartz that was deposited in between. The largest crystal measures 2.1 cm. The piece came from the Sugarbowl Pocket.

H4C-HFVMalachite : Cu2CO3(OH)2

Multiple photos available
Sacramento pit, Sacramento Hill, Bisbee, Warren District, Mule Mts, Cochise Co., Arizona, USA

Dimensions: 7.8 cm x 5.7 cm x 4.3 cm

7.8 x 5.7 x 4.3 cm. Attractive and fine quality velvety green malachite has formed gorgeous "sword"-shaped pseudomorphs after preexisting azurite aesthetically sitting on matrix. The largest crystal measures 2.5 cm. This is classic material from the Sacramento Pit/Sacramento Mine. The original Sacramento Shaft started in 1904 and produced high grade ore until 1931. The Sacramento Pit started in 1917 and both localities were exhumed by the famous large Lavender Pit in 1950. Specimens from either Sacramento locality are rare compared to other famous Bisbee mines.

RR9-V5MApache Tears

Multiple photos available
Picketpost Mountain area, Superior, Superior District, Pinal Co., Arizona, USA

Dimensions: 5.3 cm x 4.7 cm x 4.2 cm

5.3 x 4.7 x 4.2 cm. Mindat.org defines Apache Tears as a "variety of obsidian wherein the obsidian formed small droplet-shaped, spherical, or biscuit-shaped masses after being volcanically ejected and cooling as it passed through the atmosphere". These are essentially volcanic glass, but they're not opaque as they might appear on the exterior, they actually resemble smoky quartz when backlit. One of the most famous localities for the material is Picketpost Mountain area, near Superior, Arizona. This piece is a classic example of this material from the American southwest, but the most important aspect of the piece is the fact that it's actually on matrix, which is rare in my experience with the material. The actual obsidian "orb" measures 3.0 cm across. From Wikipedia: "The name "Apache tear" comes from a legend of the Apache tribe: about 75 Apaches and the US Cavalry fought on a mountain overlooking what is now Superior, Arizona in the 1870s. Facing defeat, the outnumbered Apache warriors rode their horses off the mountain to their deaths rather than be killed. The wives and families of the warriors cried when they heard of the tragedy; their tears turned into stone upon hitting the ground."

2E8-6W0Quartz (Var: Smoky Quartz) : SiO2

Multiple photos available
Crystal Peak area, Teller Co., Colorado, USA

Dimensions: 5.2 cm x 3.2 cm x 2.2 cm

5.2 x 3.2 x 2.2 cm. This specimen comes from the collection of Willard W. Wulff (1904-1998) of Colorado Springs, Colorado, a prominent figure and collector of Colorado minerals. Wulff was one of the founding members of the Colorado Springs Mineralogical Society in 1936. You can read Willard's bio on the Mineralogical Record website here (http://www.minrec.org/labels.asp?colid=1528). The piece was personally collected by Wulff in the 1960s This piece of features a sharp, very well-formed, lustrous prismatic crystal of richly colored smoky quartz. The piece is essentially a "floater" as it's crystallized "re-healed" on the bottom where it detached from the pocket wall.

FLY-XEFCalcite : CaCO3

Multiple photos available
Potosí Mine, Francisco Portillo, West Camp, Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico

Dimensions: 6.1 cm x 5.7 cm x 2.1 cm

6.1 x 5.7 x 2.1 cm. A lovely old Santa Eulalia calcite specimen, with the sharp, "jewel"-like modified rhombic crystals sitting aesthetically on a very attractively formed semi-stalactitic matrix. The calcites are sharp, well-formed and lovely to view from every angle. The largest calcite measures 1.3 cm across. From Level 16. From the collection of Senator/Dr. Miguel Romero of Teuhuacan, Mexico (Collection #8472).

Q8X-947Corundum (Var: Ruby) : Al2O3

Multiple photos available
Ampanihy District, Southwestern Region, Tuléar Province, Madagascar

Dimensions: 2.1 cm x 1.6 cm x 1.0 cm

2.1 x 1.6 x 1.0 cm. The rubies from the Ampanihy District, are among some of the lesser known but well-crystallized ruby specimens around. This specimen is a fairly sharp, well formed, lustrous, purplish-red color crystal with thick tabular hexagonal form. It seems that they are not being found as frequently as they once were.

0WV-LUKMeionite : (Ca,Na)4(Si,Al)12O24(CO3,SO4,Cl)

Multiple photos available
Pargas, Southwestern Finland Region, Finland

Dimensions: 3.1 cm x 1.8 cm x 1.7 cm

3.1 x 1.8 x 1.7 cm. A nice matrix specimen of the seldom seen scapolite (specifically meionite) from what according to the label was a locality called Ersby in Pargas, but is now simply Pargas in Finland. The material apparently earned its own varietal name back in the day as the label refers to it as "Ersbyite". A 1.2 cm sharp, well-formed, prismatic, dark yellowish-green color tetragonal crystal of meionite sits aesthetically along side the host rock matrix. Ex Kay Robertson Collection (#5901). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). A beautiful old-time specimen from this lesser known locale.

9JT-YJCAndalusite : Al2SiO5

Multiple photos available
Jenipapo district, Itinga, Minas Gerais, Brazil

Dimensions: 8.4 cm x 5.2 cm x 3.7 cm

8.4 x 5.2 x 3.7 cm. Fine crystallized andalusite is not seen from many localities around the world. The area around Jenipapo has given collectors a small amount of fine crystallized andalusite from around 10 years ago (~2007). This piece features sharp, well-formed, blocky orthorhombic crystals of pinkish andalusite intergrown with minor muscovite to form this attractive small cabinet specimen. The largest crystal measures 3.6 cm. The crystals look opaque on the surface, but when they're strongly backlit, they actually show a bit of internal color. It should be noted that andalusite is somewhat pleochroic, so when the crystals are rotated in the light, you can see a slight color change.

K6R-A84Almandine : Fe2+3Al2(SiO4)3

Multiple photos available
Sedalia Mine, Sedalia District, Chaffee Co., Colorado, USA

Dimensions: 3.1 cm x 2.8 cm x 2.4 cm

3.1 x 2.8 x 2.4 cm. The Sedalia Mine was a former copper-gold-silver producer, but is best known for its almandine crystals. This is actually a Dana locality, and has produced what are arguably the best known garnets from Colorado. This is a good sized almandine with sharp textbook dodecahedral form. It's a complete most of the way around with only a tiny bit of damage and a small point of attachment. It has this pretty "patina" look to it from a thin covering of mica that accents the deep reddish-bronze color of the crystal itself. This piece comes from the collection of Willard W. Wulff (1904-1998) of Colorado Springs, Colorado, a prominent figure and collector of Colorado minerals. Wulff was one of the founding members of the Colorado Springs Mineralogical Society in 1936. You can read Willard's bio on the Mineralogical Record website here (http://www.minrec.org/labels.asp?colid=1528). The piece comes with one of the famous 3x5 index cards that states the specimen was personally collected by Wulff himself.
