Covellite from Annie Vein, Summitville, Colorado, USA [db_pics/pics/c560a.jpg] Covellite from Annie Vein, Summitville, Colorado, USA [db_pics/pics/c560b.jpg] Covellite from Annie Vein, Summitville, Colorado, USA [db_pics/pics/c560c.jpg]

Irridescent blades of Covellite crystals in a few different areas on matrix. Ex. J.H. Marshall Jr. and Geary Murdock collections and comes with three old labels. One label indicates 'exceptionally well crystallized Covellite. One of the finest specimens I have ever seen from this locality'.


C564 - Fluorite with Quartz $ 1200
Yaogangxian Mine, Hunan, China
small cabinet - 6.2 x 6 x 4 cm


Fluorite with Quartz from Yaogangxian Mine, Hunan, China [db_pics/pics/c564a.jpg] Fluorite with Quartz from Yaogangxian Mine, Hunan, China [db_pics/pics/c564b.jpg] Fluorite with Quartz from Yaogangxian Mine, Hunan, China [db_pics/pics/c564c.jpg] Fluorite with Quartz from Yaogangxian Mine, Hunan, China [db_pics/pics/c564d.jpg]

Color-zoned purple/blue Fluorite cube with 5 terminated Quartz crystals grown along the sides.Two small trivial nicks otherwise pristine. Wonderful transparency and aesthetics.


C637 - Prehnite $ 1200
Merelani Hills, Arusha, Tanzania
small cabinet - 8 x 3.5 x 3 cm


Prehnite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c637a.jpg] Prehnite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c637b.jpg] Prehnite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c637c.jpg] Prehnite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c637d.jpg]

Along with many other 'world's best of species', Merelani produces the world's best Prehnites (in my opinion). This fantastic specimen is a complete undamaged floater that looks like it was constructed by dropping little grains of Prehnite atop each other until they formed this tall stack of crystals. The rear bottom is black from inclusions of Graphite, and there are Laumontite crystals included on one side near the base. One of the best Merelani yellow Prehnites I've owned.


C636 - Tanzanite with Calcite $ 3500
Merelani Hills, Arusha, Tanzania
small cabinet - 7 x 5.5 x 3 cm


Tanzanite with Calcite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c636a.jpg] Tanzanite with Calcite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c636b.jpg] Tanzanite with Calcite from Merelani Hills, Arusha, Tanzania [db_pics/pics/c636c.jpg]

Deep purple blue Tanzanite crystal perched atop a matrix of Tanzanite, Calcite, and Graphite. The Tanzanite is translucent with a jagged termination, and is undamaged. A fine, showy matrix Tanzanite that won't break the bank.


C661 - Tourmaline $ 3500
Himalaya Mine, Mesa Grande, San Diego Co., California, USA
small cabinet - 5.5 x 2.2 x 2.2 cm


Tourmaline from Himalaya Mine, Mesa Grande, San Diego Co., California, USA [db_pics/pics/c661a.jpg] Tourmaline from Himalaya Mine, Mesa Grande, San Diego Co., California, USA [db_pics/pics/c661b.jpg] Tourmaline from Himalaya Mine, Mesa Grande, San Diego Co., California, USA [db_pics/pics/c661c.jpg]

Large single Tourmaline crystal that grades from pink to green then back to pink at the termination. Strong color with a steep pyramidal termination. A little more pink than the photos, and the green zone is a better green, and though somewhat dark in the photos, is very gemmy. Undamaged. Weighs 67.2 grams.


C663 - Azurite on Malachite $ 1200
Mipillas Mine, Cuitaca, Sonora, Mexico
miniature - 5 x 3.5 x 2.5 cm


Azurite on Malachite from Mipillas Mine, Cuitaca, Sonora, Mexico [db_pics/pics/c663a.jpg] Azurite on Malachite from Mipillas Mine, Cuitaca, Sonora, Mexico [db_pics/pics/c663b.jpg] Azurite on Malachite from Mipillas Mine, Cuitaca, Sonora, Mexico [db_pics/pics/c663c.jpg] Azurite on Malachite from Mipillas Mine, Cuitaca, Sonora, Mexico [db_pics/pics/c663d.jpg]

Four Azurite crystals on bright green Malachite. Undamaged, visually stunning specimen.


C672 - Polybasite $ 1200
Husky Mine, Yukon, Canada
thumbnail - 2.3 x 1.5 x 1 cm


Polybasite from Husky Mine, Yukon, Canada [db_pics/pics/c672a.jpg] Polybasite from Husky Mine, Yukon, Canada [db_pics/pics/c672b.jpg] Polybasite from Husky Mine, Yukon, Canada [db_pics/pics/c672c.jpg] Polybasite from Husky Mine, Yukon, Canada [db_pics/pics/c672d.jpg] Polybasite from Husky Mine, Yukon, Canada [db_pics/pics/c672e.jpg]

Platy crystals of irridescent Polybasite. These are rare specimens collected in the 1970s and no more have been found since. Purples, greens, and yellows bounce off the surface as you turn it in hand. Main crystal is 2.3cm wide with smaller crystals attached to the backside.


C675 - Cuprite on Chrysocolla $ 1200
Mashamba West Mine, Katanga, Congo
cabinet - 12 x 8 x 4 cm


Cuprite on Chrysocolla from Mashamba West Mine, Katanga, Congo [db_pics/pics/c675a.jpg] Cuprite on Chrysocolla from Mashamba West Mine, Katanga, Congo [db_pics/pics/c675b.jpg] Cuprite on Chrysocolla from Mashamba West Mine, Katanga, Congo [db_pics/pics/c675c.jpg] Cuprite on Chrysocolla from Mashamba West Mine, Katanga, Congo [db_pics/pics/c675d.jpg]

Cuprite crystals to 1.3cm on an uncommonly wide, flat Chrysocolla covered matrix. These came out years ago and are among my favorite Cuprite specimens as the Chrysocolla really sets off the Cuprite crystals. Crystals are undamaged with many more crystals present that are completely covered by the Chrysocolla. Areas of fibrous Malachite crystals enhance the look. Undamaged.


C683 - Thaumasite $ 1500
N'Chwanning Mine, Kuruman, South Africa
miniature - 3.4 x 3 x 1.3 cm


Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683a.jpg] Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683b.jpg] Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683c.jpg] Thaumasite from N'Chwanning Mine, Kuruman, South Africa [db_pics/pics/c683d.jpg]

Thaumasite is a rare mineral in the Ettringite group, the best were found at the N'Chwanning. This is a rare matrix specimen - you used to be able to find small single crystals but now even those are hard to find. Matrix specimens were always uncommon, and I have only ever had one before, a similar piece to this one that I paid a similar price to Katherine Woest about 15 years ago. Crystals are a transparent yellow and reach 5mm in diameter. White tufts of Xonotlite are dispersed between the Thaumasite crystals.


J276 - Smithsonite on Tennantite after Azurite $ 3500
Tsumeb, Namibia
small cabinet - 7 x 6 x 3 cm


Smithsonite on Tennantite after Azurite from Tsumeb, Namibia [db_pics/pics/j276a.jpg] Smithsonite on Tennantite after Azurite from Tsumeb, Namibia [db_pics/pics/j276b.jpg] Smithsonite on Tennantite after Azurite from Tsumeb, Namibia [db_pics/pics/j276c.jpg] Smithsonite on Tennantite after Azurite from Tsumeb, Namibia [db_pics/pics/j276d.jpg] Smithsonite on Tennantite after Azurite from Tsumeb, Namibia [db_pics/pics/j276e.jpg]

Cluster of Tennantite after Azurite crystals covered by Smithsonite crystals. This is the most aesthetic example of this Tsumeb psuedomorph I have seen, and only one of very few that have the associated Smithsonite. It's a floater crystallized all around with a tall 4cm main crystal rising straight up out of the group. The small black areas are not damage - just areas where the Tennantite is corroded and Smithsonite did not grow. The main crystal is completely covered by Smithsonite on the backside and shows mostly Tennantite on the front side. Comes with a custom Lucite base that says 'Tennanite after Anhydrite", though I have only ever seen these called Tennantite after Azurite.


J256 - Bornite after Carrollite $ 1800
Kamoya Mine, Katanga, Congo (DRC)
miniature - 5 x 4.5 x 4 cm


Bornite after Carrollite from Kamoya Mine, Katanga, Congo (DRC) [db_pics/pics/J256a.jpg] Bornite after Carrollite from Kamoya Mine, Katanga, Congo (DRC) [db_pics/pics/J256b.jpg] Bornite after Carrollite from Kamoya Mine, Katanga, Congo (DRC) [db_pics/pics/J256c.jpg] Bornite after Carrollite from Kamoya Mine, Katanga, Congo (DRC) [db_pics/pics/J256d.jpg]

Large and lustrous Bornite after Carrollite crystal, 3.5cm wide, on a Bornite matrix with other smaller crystals. The price would be justified simply as a Carrollite of this size and quality on matrix, but even more so as this uncommon psuedomorph, it's really special. Analyzed.


J305 - Bismuth with Fluorite $ 1500
Dolcoath Mine, Camborne, Cornwall, England
miniature - 3.8 x 3.3 x 1.0 cm


Bismuth with Fluorite from Dolcoath Mine, Camborne, Cornwall, England [db_pics/pics/J305a.jpg] Bismuth with Fluorite from Dolcoath Mine, Camborne, Cornwall, England [db_pics/pics/J305b.jpg] Bismuth with Fluorite from Dolcoath Mine, Camborne, Cornwall, England [db_pics/pics/J305c.jpg] Bismuth with Fluorite from Dolcoath Mine, Camborne, Cornwall, England [db_pics/pics/J305d.jpg]

Historic specimen of crystallized Bismuth with Fluorite. Comes with old labels from Cal Graeber, the Nick Carruth collection, and Ward's Natural Science.
