Koksha Valley, Badakhshan, Afghanistan
3.3 x 3.2 x 3.0 cm

Calcite great luster Santa Eulalia Mexico small cabinet

Calcite - SOLD
Santa Eulalia Dist., Chihuahua, Mexico
7.3 x 7.1 x 4.6 cm


MMB-700 - Boasting great luster and complex crystallization, this fine quality calcite specimen has several isolated crystals (to 3.5cm) colored red with hematite inclusions. The larger crystals formed after an earlier growth of calcite rhombs, some colored by hematite, some clear, and some colored yellow by an unknown agent. Overall, the piece is all flash...very attractive and significantly better in person!

 

 

 

 

   
Wulfenite Tsumeb Namibia small cabinet

Wulfenite - SOLD
Tsumeb, Otjikoto Region, Namibia
8.8 x 5.1 x 4.0 cm


MMB-698 - A cluster of wulfenite crystals (to 2.0cm) with color reminiscent of cream soda formed on a ridge of matrix in this superb specimen from Tsumeb. The quality and intricacy of the transparent crystals is very difficult to convey in the photos. Wulfenites from this world-famous mine are quite rare.

Apatite - SOLD
Durango, Mexico
6.3 x 5.4 x 4.5 cm

MMB-766 - A gorgeous lemon yellow apatite crystal measuring 4.5 cm rests on its host matrix in this fine small cabinet specimen from Mexico. The upper third of the crystal is particularly transparent, and the overall crystal is gemmier than the photos can indicate. Matrix specimens from Durango are few and far between.

MMB-764 - Dueling for the eye's attention, a pair of quite gemmy, deep green emerald crystals (to 2.5 cm) nestles among smoky calcite crystals in this fabulous thumbnail. Both crystals are transparent enough that you are looking right through them in the photos shown here. Take our word for it, this is a world-class thumbnail that would strengthen any collection.

 

 

 

 

 

 

 

Adamite Kamareza Mine Laurium Greece cabinet specimen

Adamite - SOLD
Kamareza Mine, Laurium, Greece
12.1 x 4.1 x 3.2 cm

– ex Robert M. Philips Collection

MMB-767 - Interlacing, fabric-like folds of matrix are completely covered by sea-foam green balls of adamite in this superb cabinet specimen from Greece. The mines in Laurium have been worked since Ancient Times, shaping the course of entire empires. Aside from its historical interest, this is just a lovely piece! Note that the color is richer than the photos indicate, without the white areas caused by the transparency of the adamite.

8.8 x 6.2 x 3.8 cm

Lepidolite - SOLD
Newry, Maine, USA
5.0 x 4.6 x 4.0 cm

 

MMB-770 - Known primarily as an associated mineral found in pegmatites around the world, lepidolite can serve as an attractive specimen alone when reaching large crystal sizes and thicknesses. Note the attractive lilac color exhibited when the piece is backlit. This particular piece comes from the famous Newry area of Maine.

 

 

 

 

 

 

 

Gersdorffite Bou Azzer Morocco fine crystal

Gersdorffite - SOLD
Aït Ahmane, Bou Azzer, Morocco
3.0 x 1.9 x 2.0 cm

MMB-765 - Rarely forming in octahedral crystals such as this, gersdorffite is a nickel arsenic sulfide (NiAsS--spelling correct here ???) usually found as cleaved masses or grains. The material is fragile and cleaves easily, thus fine specimens are difficult to acquire.

 

 

 

 

 

 

 

Calcite on stalactite Santa Eulalia Mexico cabinet specimen

Calcite Stalactite - SOLD
Santa Eulalia, Chihuahua, Mexico
9.7 x 2.8 x 2.8 cm

MMP-2001 - Natural sculpture! A lustrous, complex calcite crystal faintly colored by hematite inclusions clings to a stalactite richly covered by an earlier generation of calcite. The specimen is pristine from all angles. Specimens of this type were mined in the mid-90's and continue to dazzle to this day.

Titanite - SOLD
Zagi Mountain, Mulla Ghori, Pakistan
5.1 x 4.2 x 2.4 cm


MMB-707 - Several pristine, golden-green titanite crystals rise from a matrix of unidentified black crystals (schorl?). The beautiful color, crystal perfection, and contrasting matrix all combine to make this a top-notch miniature specimen. Crystals of this quality are very difficult to replace, especially in today's market.

 

 

 

 

 

 

 

Ferro-axinite New Melones Dam California miniature

Axinite - SOLD
New Melones Dam, Calaveras Co., California
4.4 x 3.2 x 1.8 cm


MMB-737 - This ferro-axinite crystal not only shows quite a bit of transparency near the termination but also hails from the well-known American locality of New Melones Dam in California. And you thought only frogs were famous in Calaveras County! The specimen effortlessly shows its strong dichroism--clove brown and amethystine. The specimen is better in person than photos indicate.

MMB-705 - A colorless, transparent calcite crystal encases arborescent copper in this attractive "toenail" (small miniature) specimen formerly belonging to the famous Dawn & Jim Minette Collection.

Cassiterite gemmy Amo deposit Yunnan Province China small cabinet specimen

Cassiterite - SOLD
Amo deposit, Ximeng Co., Yunnan Prov., China 
6.7 x 6.0 x 5.5 cm


MMB-694 - Showing high luster and the transparency that has put this deposit on the map, this large cassiterite cluster would make a weighty addition to any collection of Chinese or world-wide minerals. The cluster is quite complex and rather attractive...nicer than the opaque specimens one typically sees.

4.6 x 4.2 x 3.7 cm

MMB-706 - Lustrous, purple apatite crystals with vibrant blue phantoms and complex terminations (most of the crystals are doubly-terminated!) are generously scattered across the matrix in this fine miniature specimen from Brazil. The specimen is a treat to hold in the hand and examine all the intricate details. This piece is substantially better than can be captured by the photographs.
