AF930 - Libethenite $ 200 (=~ £ 129)
Rokana Mine, Kitwe, Zambia
thumbnail - 3 x 2.2 x 1.2 cm
Three dark forest green Libethenite crystals that contrast nicely against the lighter colored matrix. This locality produced the world's best Libethenite, and this is a choice thumbnail from that find. Undamaged.
AF931 - Demantoid Garnet $ 425 (=~ £ 274)
Erongo Mountains, Namibia
thumbnail - 2.5 x 2.3 x 2.0 cm
Fine, 1.2 cm Demantoid crystal perfectly perched atop matrix. The crystals has a great green color and is translucent with lots of gemmy zones. Undamaged specimen that stands out amongst others from this locality.
A864 - Indicolite $ 1500 (=~ £ 966)
Kunar Prov., Afghanistan
thumbnail - 2.2 x 1.5 x 1.0 cm
Fine gem quality Indicolite perfectly accented with some attached Albite at the base. Undamaged.
A866 - Zoisite $ 1400 (=~ £ 901)
Alchuri, Skardu District, Pakistan
thumbnail - 2.6 x 2 x 1.1 cm
Green "Tanzanite" crystal from Pakistan. These have always been intriguing to me as only the second locality I'm aware of that produces gem quality Zoisite, however production was always very sporadic and nothing has been turning up for years. I bought this about 15 years ago and it has been in my collection ever since. The left side of the crystal has some gemmy zones with great green coloration. Complete all around.
A869 - Liddicoatite $ 100 (=~ £ 64)
Minh Tien, Luc Yen, Yen Bai Prov., Vietnam
thumbnail - 2.5 x 1.3 x 0.6 cm
Color zoned pair of Liddicoatite crystals with three distinct color bands, yellow to green with a red termination. The green band is unusually distinct. A somewhat flattened crystal which really allows the light to pass through and show off the colors. Lustrous and undamaged.
A870 - Apatite $ 75 (=~ £ 48)
thumbnail - 2.1 x 1.5 x 1 cm
Terminated, translucent orange/pink Apatite crystal on a bed of Quartz crystals.
NA213 - Pyrargyrite $ 800 (=~ £ 515)
Fresnillo, Zacatecas, Mexico
thumbnail - 2 x 1.8 x 1.8 cm
Thick, lustrous, and complete Pyrargyrite that lights up a bright cherry red with backlighting. Undamaged, acquired from the Gebhard collection.
NA214 - Calcite $ 150 (=~ £ 97)
Norrie Mine, Gogebic Co. Michigan
thumbnail - 3 x 3 x 2.5 cm
Spherical Calcite 1.9cm in diameter with a pinkish hue. The Norrie Mine is an old iron mine and the Calcite sits atop a matrix of Limonite.
NA215 - Silver $ 1600 (=~ £ 1030)
Kearsarge Mine, Houghton Co., Michigan
thumbnail - 2.5 x 1.5 x 1.4 cm
Dramatic cluster of angular Silver crystals, capped by a superb 1.2cm crystal. Tiny amounts of Copper are present on some of the crystal faces. Nothing but good, large crystals. Fine!
SA559 - Rhodochrosite $ 950 (=~ £ 612)
Uchucchacua Mine, Oyon Prov., Peru
miniature - 3.3 x 1.4 x 1.2 cm
Large single Rhodo of an unusual style, different from others I have seen from this locality. The prism faces, and even the bottom, are coated in a thin layer of quartz crystals with the termination faces exposed. The terminations are not cleavages as there are areas on the very edges of the termination faces that also have small amounts of the Quartz crystals. Undamaged and complete. One photo is backlit to show the translucency of the crystal.
AF935 - Chondrodite with Magnetite $ 3200 (=~ £ 2060)
Palabora Open Pit, Phalaborwa, Transvaal, South Africa
small cabinet - 5.5 x 4.5 x 3.5 cm
Fiery red/orange, gemmy 1cm Chondrodite on matrix with oriented Magnetite crystals. Collected by J.P. Gliddon and considered by him to be one of the finest Chondrodites to ever be found a Palabora. The color and luster of the Chondrodite is superb (no brown overtones like so many Chondrodites), and the lustrous, triangular faces of the Magnetite, all in parallel growth, create a great effect.
AF937 - Azurite $ 1000 (=~ £ 644)
Touissit Mine, Morocco
miniature - 3.5 x 3.1 x 1.9 cm
Cluster of dark blue Azurite crystals which are translucent along the edges when backlit. Complete all around and undamaged (except for one tiny 2mm ding) with alteration to Malachite in areas around the base. Excellent luster on the Azurite. Looks like Tsumeb, but it's Toussit.
A888 - Apophyllite $ 400 (=~ £ 257)
Jalgaon, Maharashtra State, India
small cabinet - 5.2 x 4.5 x 3 cm
Amazing double terminated Apophyllite crystal atop stalactitic quartz. The Apop is 4.9cm wide. I used to import hundreds of Indian minerals years ago, this was one of the very few that really stood out and was kept in my collection.
A889 - Apophyllite $ 350 (=~ £ 225)
Jalgaon, Maharashtra State, India
small cabinet - 5.2 x 4 x 3 cm
Amazing double terminated Apophyllite crystal atop stalactitic quartz. The Apop is 4cm wide. I used to import hundreds of Indian minerals years ago, and this one was one fo the select few out the many hundreds in those parcels that I kept for my collection.
A892 - Aquamarine $ 700 (=~ £ 451)
Skardu District, Pakistan
miniature - 3.2 x 1.9 x 1.8 cm
Gem quality single Aqua crystal I bought at the Tucson show around 1990. Aside from being a high quality gem crystal, it has the added appeal of having a number of unusual negative crystals included within that appear to be octahedral in shape.
