Beryl var. Aquamarine - SOLD
Shigar Valley, Baltistan, Pakistan
6.7 x 2.9 x 2.0 cm

MMS-230 - Water-clear and pristine, this aquamarine crystal looks like the creation of some master architect. The bevelled edges and complex termination are beautiful, but the real wonder of the piece comes from the twisted look of the crystal. A bit of albite matrix is attached. The piece is undamaged with very minor contacting next to the existing matrix. A true natural sculpture the like of which we have not seen in our 25 years of working with fine minerals.

Adamite on Goethite - SOLD
Ojuela Mine, Lvl 4, Mapimi, Durango, Mexico
14.1 x 11.3 x 10.2 cm
—ex Smithsonian

MMS-283 - Large, yellow-green balls of adamite (to 6.6 cm wide) fill a goethite-lined limonite vug in this substantial piece from Level 4 of the world-famous Ojuela Mine. The specimen is completely undamaged. In front of the large balls, hemispheres of adamite display the radial crystallization which forms the spheres.

Brookite on Quartz - $6500
Taftan, Chagai Dist., Baluchistan, Pakistan
7.0 x 4.3 x 3.0 cm

MMS-264 - A perfect mahogany-colored brookite crystal (2.6 cm) juts out from within a cluster of pristine and lustrous quartz crystals. The piece has a quality to it that is difficult to convey in pictures (or words) but must be seen to fully appreciate. A world-class brookite specimen!

Azurite with Malachite - SOLD
Bisbee, Warren Dist., Cochise Co., Arizona, USA
8.3 x 6.5 x 3.1 cm

MMS-241 - With wet luster and a vibrant blue color, a cluster of sharp azurite crystals sits on top of a goethite matrix covered with circular malachite balls and secondary azurite crystals. Bisbee azurites are famous the world over, and this specimen would make a prized addition to any Bisbee suite or worldwide collection.

Neptunite - $500
Dallas Gem Mine, San Benito Co., California
3.8 x 3.2 x 1.0 cm

MMB-591 - With the level of quality and aesthetics one should expect from a miniature, this neptunite specimen features a pair of lustrous, sharp crystals with the largest (doubly-terminated!) crystal measuring a full 3.1 cm. This locality is better known for its benitoite specimens, but it also produced neptunite that is arguably the world's best.

Apophyllite - $175
Nasik District, Maharashtra, India
6.5 x 4.4 x 4.0 cm

MMB-687 - A pair of apophyllite crystals has been colored a rich, attractive blue-green color by chlorite inclusions. While the specimen has not been analyzed, we expect that the butterscotch coloration is caused by the rare mineral mozartite. A secondary mineralization of small, spherical crystals adds a texture contrast.

Schorl Tourmaline - SOLD
Erongo Region, Namibia
9.3 x 5.8 x 5.5 cm

MMB-669 - A complex cluster of mirror-bright schorl tourmalines shows no attachment point--the piece is a floater! There is no damage on the specimen, and the specimen can be displayed from any angle. The intricacies of this piece rival any man-made sculpture.

Zircon - ON HOLD
Tanga Region, Tanzania
3.5 x 1.8 x 1.4 cm

MMB-691 - With rich, wine red color and adamantine luster, this zircon single crystal specimen is a beauty! Missing is the brown component that most specimens possess. The sharp edges and faces show only the markings that testify to its formation and journey through the depths of the earth. Specimens of this color typically do not escape the cutter's wheel, but this was saved out of recognition of its natural beauty and rarity.

Silver - SOLD
Uchucchacua Mine, Oyon Prov., Lima Dept., Peru
9.5 x 3.0 x 3.4 cm

MMB-632 - A looping silver wire rises from its matrix of ore like a curl of smoke. The silver measures 6.5 cm and is partially coated by secondary mineralization. A fine small cabinet silver specimen from the famous Peruvian silver mine of Uchucchacua.

2.1 x 2.8 x 1.9 cm
