Sturmanite and Brucite
stock #Alec 14-266
N'chwaning Mine, Kalahari Fields, Kuruman
Kuruman, South Africa
14 x 6.8 x 7.6 CM (cabinet)
price: $1250
Spring 2014

A exceptional cabinet sized combo specimen hat presents well these two relatively rare species. Gemmy yellow Sturmanite in flattened blade habit crystals reach 1.8 CM scattered on a sparkling matrix of micro Manganites which is also the host for the spheres of blue green to white Brucite. The Brucite has the most desirable "wet" luster and shows good color gradations across the piece. In excellent condition and quite pretty for a "rarities mix". This piece almost certainly originated at the N'Chwanning mine (perhaps the only place this combo is noted) but the labeling we have for it is not that specific.
Olmiite with Calcite
stock #14-14-260
N'chwaning Mine, Kalahari Fields, Kuruman
Kuruman, South Africa
9 x 6.8 x 6 CM (cabinet)
price: $1250
Spring 2014

A large and esthetic 3-D cluster of Olmiite in "wet look" aggregates with a pinkish color. Far better that the average, this is an even more special specimen due to the well placed clear clusters of Calcites in parallel growth. The calcite is in doubly terminated prisms that look very much like quartz and have similar glassy luster. Olmiite was unknown as a mineral until 2006, it is only found at this one location worldwide. This piece displays well, is undamaged and presents from several angles.
Quartz V. Amethyst with scepters
stock #Alec 24-122
Cerro de Concordia, Piedra Parada
Veracruz, Mexico
4.8 x 4.5 x 1.8 CM (miniature)
price: $240
Spring 2014

From the newest find at Cerro de Concordia, a pretty spray with distinct sceptering of the main crystal. Bright, colorful and undamaged with attractive form. There are some tiny orange flake-like inclusions as well.
Gratonite (rare Lead-As Sufosalt)
stock #13.1-379
Excelsior Mine, Cerro de Pasco, Pasco Province
Pasco Department, Peru
5.4 x 3.2 x 2 CM (small cabinet/large miniature)
price: $400
Spring 2014

Gratonite when available is usually in thumbnail sized pieces. This is a more sizable piece and well crystallized. The best were found over 50 years ago and Pasco is the only source for fine specimens. Branching crystal aggregates to 2.5 CM cover most of a sulfide matrix, composed of 3-5mm sized individuals. The Gratonite has the dull to slightly lustrous lead-silver color that is classic for these.
Cerussite (gemmy V twins)
stock #Alec 12-072
Tsumeb
Otavi-Bergland district, Oshikoto, Namibia
5.2 x 4 x 2.1 CM (small cabinet/ large miniature)
price: $540
Spring 2014

Tsumeb Cerussite can be incredible, but its usually very damaged or crazy expensive. This is a far better than average piece (but not perfect with inspection) with glassy luster, elegant striations, and is formed by 2 "V" twins that abut each other. The main large crystals are in good undamaged condition, there is chipping on the bottom and end of the small crystals that is seen. The chipping is not glaring, only noted if you look carefully. The clarity is gem grade and very sharp, with a warm smokey color. Not perfect, but not 8,000.00$ either!
Realgar in and on Calcite
stock #4.2-107.1
Shimen (Jiepiayu) Mine, Shimen County, Changde Prefecture
Hunan, China
7 x 5.5 x 4.8 CM (cabinet)
price: $145
Spring 2014

A very attractive bright specimen that has become sort of a modern classic from the Realgar mine at Shimen. The calcite is milky white to clear yellow and glassy, while the Realgar is brilliant red. This is clearly seen inside the Calcites and extending to the surface in sharp form. In good condition with some bruising that is not distracting, specimen like this one are a great value for building collections with attractive pieces that are fine yet affordable.
Andradite with Calcite
stock #Alec-14-385
N'chwaning Mine, Kalahari Fields, Kuruman
Northern Cape Province, South Africa
2.8 x 2.5 x 1.4 CM (thumbnail)
price: $330
Spring 2014

An unusually good, sizable crystal aggregate of Kalihari Andradite Garnet. The great NChwaning mine is famous for its red colored minerals, especially the Rhodochrosites. Many other less colorful species from here are dusted with tiny bright red Andradites, typically micro crystals. This piece shows well formed distinct and colorful crystals very sizable not like what is usually seen. In excellent condition.
Malachite psudo after Azurite (huge crystal)
stock #Alec3-408
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
8.5 x 5.7 x 3.2 CM (cabinet)
price: $1400
Spring 2014

An extremely large (over 3-1/2 inches) single compound crystal of Azurite is partly altered to a silky green Malachite, yet still has large areas of deep blue. Somewhat blocky and crude but with strong and clear form this is an impressive piece and one of the largest single crystal psudos that have come from this prolific location. Esthetic and with strong display presence, this was mined in 2011. A very good value.
