K305 - Prehnite with Calcite, Tanzanite $ 1800 (=~ € 1645) Merelani Hills, Arusha, Tanzania small cabinet - 8.5 x 5 x 4 cm Individual spheres of yellow Prehnite grown in and around flat crystals of white Calcite. This is one of the most beautiful Merelani Prehnites I've ever seen. A fibrous blue Tanzanite and small white crystals (Laumontite?) are attached to the backside. A floater with no points of attachment and little to no damage.
MM102 - Calcite $ 1600 (=~ € 1462) Hercules Mine (Negra Mine), La Negra, Mun. Sierra Mojada, Coahuila, Mexico small cabinet - 9 x 8 x 5 cm Spectacular, bright and gemmy Calcite crystals on matrix. Incredibly beautiful Calcite from a little know Mexican locality. Main crystal is 6.5cm tall and accented by numerous smaller crystals. Undamaged. Much better and brighter in person.
MM118 - Hematite with Quartz $ 2500 (=~ € 2284) Big Bertha Mine (Veta Grande Mine), Dome Rock Mts, La Paz Co., Arizona, USA small cabinet - 6 x 4.5 x 3.5 cm Stunning Hematite and Quartz specimen from the classic Arizona locality, likely from the late 1970s. Mirror lustrous tabular crystals to 1.9cm. Comes with an old Larry Conklin label that shows a price of $550 likely from decades ago. There are some small damaged crystals, still this is by far the best I've owned or seen, though admittedly I have not seen many - they are uncommon, Mindat only shows 18 specimens.
AB113 - Tanzanite $ 3000 (=~ € 2741) Merelani Hills, Arusha, Tanzania miniature - 4 x 2.2 x 0.7 cm Stunning bi-color Tanzanite crystal of yellow over vivid purple/blue. This crystal has superb luster and unusually uniform shape, retaining an even 7mm thickness all the way from the base to the termination. There are two chips, including one on the back termination, but the sheer pizzaz and dramatic coloration greatly overcomes it, it's that pretty and unique. The best bi-color Tanzanite I've ever had. Weighs 13 grams.
K965 - Rhodochrosite $ 2800 (=~ € 2558) N'Chwanning Mine, Kuruman, South Africa miniature - 3.8 x 3 x 2 cm Crystals of translucent Rhodochroiste over a small bit of Manganite matrix. Undamaged.
M379 - Dravite $ 1200 (=~ € 1096) Mwajanga, near Komolo, Tanzania cabinet - 10.5 x 3 x 2 cm Large, doubly-terminated blue-cap Dravite from a unique 2017 find. This one has so many things going for it, most importantly it's large size and good condition with only one bit of chipping along the termination. It features a dark body grading up to a translucent white zone followed by an intensly blue termination. While the dark zone in the majority of the crystals were opaque, this one is translucent, even despite it's larger size (I put a pen light behind it in one photo to show the translucency). The other end is terminated with a more pyramidal shape and has green overgrowths. There is another small Dravite intergrown in this end.
M608 - Platinum $ 1200 (=~ € 1096) Konder, Khabarovsk Region, Russia thumbnail - 0.7 x 0.7 x 0.5 cm Partial cube of Platinum with a smaller attached crystal. Platinum crystals are much more rare than the nuggets and most are much more rounded than this one, in fact it was the sharpest, most well formed by far of a small lot of crystals I examined. It has stepped faces all around, well crystallized and undamaged. I understand these are no longer being found. Weighs 1.57 grams.
M626 - Tanzanite with Diopside $ 1500 (=~ € 1370) Merelani Hills, Arusha, Tanzania thumbnail - 3 x 2.7 x 2.1 cm Uncommon, aesthetic Merelani specimen consisting of two terminated Tanzanite crystals associated with Diopside. Stands upright on it's own and is complete all around. There is a small chip on the backside of the larger 3cm crystal, otherwise perfect and undamaged all around. Unheated and natural. Really stands out from the more commonly seen single crystals.
TR103 - Stibiotantalite on Tourmaline, Topaz $ 6000 (=~ € 5482) Shengus, Skardu, Pakistan small cabinet - 5.5 x 4 x 3.5 cm Cluster of transparent green Tourmaline crystals, a 3.2cm Topaz crystal, Muscovite, and lots bright yellow Stibiotantalite. This is one of the richest Stibiotantalite specimens I've seen, which by itself would be special. But the association of the gemmy Tourmaline crystals and the Topaz makes this a real stunner. Undamaged. It has also not been professionally cleaned, which could further enhance it's beauty.
M913 - Tourmaline $ 2000 (=~ € 1827) Paprok, Kamdesh District, Nuristan, Afghanistan small cabinet - 5.5 x 2.2 x 1.5 cm Highly aesthetic cluster of 4 intergrown Tourmaline crystals with alternating colors of green and red. Interestingly, the taller crystals have more typical terminations and the shortest crystals has a more flat termination face. Undamaged.

One end shows cat's-eye growth and has an attached cluster of Lepidolite. Complete and undamaged. Weighs 76.3 grams.

Cut parallel to the C-axis, the slice reveals the colorful interior of what would have appeared to otherwise be a dark crystal. Triangular color zoning of greens, blues, and purple. Well polished on both sides, weighs 87.09 grams.
CT682 - Tetrahedrite $ 1200 (=~ € 1096) Peru miniature - 4.5 x 3.5 x 3 cm Large single Tetrahedrite, 3.5cm with some smaller attached crystals. Excellent size and undamaged with a slight coating of Chalcopyrite in areas. Ex. Chuck Trantham collection.
