MK173 - Sapphire $ 2000 Mahenge, Morogoro, Tanzania small cabinet - 6 x 4 x 3.5 cm ![]() ![]() ![]() ![]() ![]() Pair of large pink Sapphire crystals from Tanzania. Two hexagonal prisms that have grown side by side, the largest 6cm and doubly-terminated. Displays well from the front but backside is more rough (as shown). Glows bright red under UV light. Impressive large Sapphires!
MK176 - Austinite $ 1250 Ojuela Mine, Mapimi, Durango, Mexico cabinet - 9.5 x 6.5 x 5 cm ![]() ![]() ![]() ![]() Thick botryoidal masses of translucent yellow Austinite over a Limonite matrix. Usually found as thin crusts with crystalline surfaces or small 'gumdrop' formations, this specimen is both unusual and exceptional, easily the best I've ever owned.
MK179 - Amethyst $ 350 Las Vigas, Vera Cruz, Mexico cabinet - 10 x 9 x 2.5 cm ![]() ![]() ![]() Three large, doubly-terminated Amethyst crystals. The crystals are glassy and gemmy with the largest crystal crossing across the top and 9.2cm wide. All the large crystals are complete all around and undamaged. There is a tiny crystal growing off the largest crystal that has an indentation from another crystal, but even this one is perfect with a thin, small undamaged termination.
MK180 - Olivenite $ 250 992 Level, Milpillas Mine, Cuitaca, Sonora, Mexico thumbnail - 1.4 x 0.7 x 0.3 cm ![]() ![]() ![]() ![]() Cluster of well terminated Olivenite crystals from the Milpillas Mine. Like many other minerals found at this mine, these rank among the world's best for species. Slender flattened prisms with glossy luster. Complete all around and undamaged.
MK183 - Cerussite (R) Ojuela Mine, Mapimi, Durango, Mexico miniature - 4 x 1.8 x 1.3 cm ![]() ![]() ![]() Thick, transparent colorless Cerussite crystals, shocking in size and quality for the locality. This is from a recent find and look more like something you would see from Tsumeb than any I've ever seen from the Ojuela Mine. The specimen is composed of a large single crystal with a smaller V-twin attached. Unfortunately while photographing, the small V-twin detached from the main crystal and I had to therefore reattach it (the smaller crystal fits perfectly into an angular groove on the larger crystal like a puzzle piece).
