R613 - Prehnite on Epidote sold
Djouga Diggings, Diakon, Kayes Region, Mali
Small Cabinet - 6.5 x 3 x 3 cm
Sculptural specimen composed of interconnected, translucent spheres of green Prehnite atop Epidote crystals. This is formerly a Tim Sherburn collection specimen. Tim used to buy these uncleaned in bulk, trim and clean them, and then sell them individually to collectors. This is a top specimen from the many thousands he cleaned, probably the most aesthetic, at least the prettiest I can recall ever seeing.
R614 - Kammererite sold
Kop Krom Mine, Kop Daglari, East Anatolia, Turkey
Small Cabinet - 5.5 x 3.5 x 2.5 cm
Colorful specimen of the chromium rich Clinochlore varietal known as Kammererite from the world's best locality for the species. This is an excellent example with many large, deep purple crystals and a bonus of white Calcite crystals, which are uncommon to find on these. This locality is long closed and specimens are now hard to come by. Two different display orientations are shown.
R615 - Aquamarine sold
San Diego Co., California, USA
Miniature - 4.2 x 3 x 1.5 cm
Transparent, light blue Aquamarine crystal with attached Albite and Muscovite. Well crystallized all around and undamaged. This was in an old collection and came with an American Museum of Natural History label. The label only notes 'San Diego Co., California' and could possibly be from the Pack Rat Mine.

Merelani Hills, Arusha, Tanzania

R617 - Turquoise sold
Kingman, Cerbat Mountains, Mohave County, Arizona, USA
Miniature - 4.2 x 3.5 x 2 cm
Nodule of rich blue Turquoise from the famous Kingman mine in Arizona. Beautiful, uniform sky-blue color. Weighs 45.7 grams.
R618 - Apophyllite over Calcite with Quartz sold
2nd Sovetskii Mine, Dalnegorsk, Primorsky Krai, Russia
Small Cabinet - 6 x 4 x 3 cm
Disc-shaped Calcite crystals on a matrix covered by clear Quartz crystals. The Calcite are coated by tiny, sparkling Apophyllite crystals with a reddish coloration. This reddish coloration is unusual as most of these I've ever seen are Calcites coated by colorless Apophyllite. An uncommon beauty!
R619 - Tourmaline sold
Batalha Mine, Salgadinho, Paraiba, Brazil
Small Cabinet - 5.2 x 1.5 x 0.7 cm
Cluster of translucent blue, terminated Tourmaline crystals from Paraiba, Brazil. Though not as vivid or transparent as some, it's a nicely terminated, representative crystal from the mine that's not been carved out of solid Quartz or one that will cost you five figures!
R620 - Prehnite $750 available

Miniature - 3.5 x 2.2 x 2.2 cm
