11R-KG9Sodalite : Na8(Al6Si6O24)Cl2

Multiple photos available
Princess Sodalite Quarry, Dungannon Township, Hastings Co., Ontario, Canada

Dimensions: 7.3 cm x 6.2 cm x 4.1 cm

7.3 x 6.2 x 4.1 cm. A rich representative sample of deep navy blue colored sodalite from the Princess Sodalite Quarry in Ontario, Canada. This is excellent older material with good color, and is cutter grade. Ex Kay Robertson Collection (#1325). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

KAN-8VUTopaz : Al2(SiO4)(F,OH)2, Quartz (Var: Smoky Quartz) : SiO2, Albite (Var: Cleavelandite) : Na(AlSi3O8)

Multiple photos available
Government Pit, Albany, Carroll Co., New Hampshire, USA

Dimensions: 8.3 cm x 6.3 cm x 4.8 cm

8.3 x 6.3 x 4.8 cm. A true classic from New Hampshire. Sharp, well-formed, translucent, soft blue color crystals of topaz measuring up to 1.0 cm are associated with smoky quartz on bladed albite (var. cleavelandite) matrix from the Government Gravel Pits locality. Matrix specimens are nearly impossible to find as most specimens we've seen over the years are loose single topaz crystals off matrix. Ex Kay Robertson Collection (#8772). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

UYL-LKLTremolite (Var: Hexagonite) : ☐{Ca2}{Mg5}(Si8O22)(OH)2

Multiple photos available
Gouverneur Mine, Fowler, St. Lawrence Co., New York, USA

Dimensions: 7.5 cm x 3.6 cm x 1.2 cm

7.5 x 3.6 x 1.2 cm. A classic example of the pinkish-lilac hexagonites (a manganoan variety of tremolite) from one of the few known localities for the material. Hexagonite is only found in New York state, and the pieces from the Gouverneur Mine are iconic. This is not a massive specimen of hexagonite, but rather shows defined crystal faces on both the front and back. One particular 3.1 cm crystal stands out on the specimen as it's darker and gemmier than anything else on the piece. Ex Kay Robertson Collection (#899). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

4LJ-Y9YGypsum : CaSO4·2H2O

Multiple photos available
Gaurdak basin, Chardzhou, Lebap Province, Turkmenistan

Dimensions: 6.1 cm x 5.3 cm x 3.2 cm

6.1 x 5.3 x 3.2 cm. Mineral specimens of any type are rare from this obscure, large marine basin that hosts large potash deposits (MINDAT). This is a rare and very striking, water-clear gypsum crystal with a beautiful termination. The piece is completely colorless and despite some separation marks where other crystals grew, this is a significant and hard-to-find gypsum specimen. Ex Kay Robertson Collection (#12213). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

TG8-1J6Dioptase : CuSiO3·H2O

Multiple photos available
Magma Mine, Superior, Pioneer District, Pinal Mts, Pinal Co., Arizona, USA

Dimensions: 5.6 cm x 3.0 cm x 3.0 cm

5.6 x 3.0 x 3.0 cm. A hard-to-find dioptase specimen from the Magma Mine. Sparkling, emerald green color micro crystals of dioptase cover the upper front face of this small cabinet piece. Ex Kay Robertson Collection (#651). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

346-D8JHureaulite : Mn2+5(PO3OH)2(PO4)2·4H2O

Multiple photos available
Jocão pegmatite, Conselheiro Pena, Minas Gerais, Brazil

Dimensions: 4.3 cm x 4.0 cm x 3.7 cm

4.3 x 4.0 x 3.7 cm. Hureaulite is a rare and beautiful manganese phosphate that was named in 1825 after the type locality, a village in France by the name of Hureaux. Arguably the best and most well-known samples are those from the Jocão pegmatite in Brazil with their glowing electric orange-pink crystals in larger sized crystals (most other hureaulites are micro crystals from various localities around the world). This piece is a superb, classic specimen of hureaulite featuring notably sharp, lustrous, translucent, vibrant orange-pink colored monoclinic crystal groups. The largest cluster of crystals measures 8 mm long. The matrix features a dark mineral (most likely rockbridgeite or possibly phosphosiderite (?)). From the collection of Rolando Gioia (a contributor to the new definitive book on Brazilian minerals: "Minerais e Pedras Preciosas do Brasil").

1LT-T74Quartz : SiO2, Quartz (Var: Chalcedony) : SiO2

Multiple photos available
Zhob District, Balochistan, Pakistan

Dimensions: 4.7 cm x 2.3 cm x 2.1 cm

4.7 x 2.3 x 2.1 cm. A rarely seen example of quartz transitioning into chalcedony from Zhob. The piece features several sharp, prismatic crystals of gem quality, colorless quartz, but some of them actually start to transition into slightly milky white chalcedony at the top portion of the crystals. Some of the quartz crystals are completely transparent, while others show the gradual change into chalcedony. The largest crystal measures 2.0 cm long. Some of the crystals have slight "scepter" habit terminations. The matrix features small compressed rhombic crystals of golden calcite surrounding the bases of the quartz crystals. Rare and unusual material. Ex Herb Obodda specimen.

83T-8Q0Corundum (Var: Ruby) : Al2O3

Multiple photos available
Winza, Mpapwa, Mpwapwa District, Dodoma Region, Tanzania

Dimensions: 1.1 cm x 0.7 cm x 0.6 cm

1.1 x 0.7 x 0.6 cm. A good representation for this locality, here is a beautiful gemmy, electric pink ruby crystal with great luster and some very sharp crystal faces. This piece came out after the handful of superb specimens we have seen from Winza over the last few years. Weight is 1.09 grams (5.45 carats).

Dimensions: 13.2 cm x 7.2 cm x 3.6 cm

13.2 x 7.2 x 3.6 cm. This piece features sharp, very lustrous, translucent, white adularia crystals on matrix. The largest adularia measures 2.1 cm. Ex Herb Obodda specimen.

31M-9UWSmithsonite : ZnCO3

Multiple photos available
Kelly Mine, Magdalena, Magdalena District, Socorro Co., New Mexico, USA

Dimensions: 3.8 cm x 3.2 cm x 2.8 cm

3.8 x 3.2 x 2.8 cm. This piece features lustrous/vitreous, beautiful blue color radiating aggregates and classic "rice grain"-shaped groups of smithsonite on matrix. A good representative piece of this classic material from New Mexico. 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).
