Rich chrome green Diopside crystal from the famous December 2007 find that produced Diopsides with a vivid, rich green color, far and away better than average Merelani Diopside. This is a fine single crystal complete all around with good luster. Undamaged.

Unusual etched chrome green Diopside crystal. This was mined in 2016 and was the only one like it I saw, or have ever seen. The color is incredible and it is fully transparent facet grade.

Unusual deep blue Tanzanite crystal with a bubbly green/brown mineral attached the sides and back. On the backside, underneath this mineral, are Prehnite crystals. Complete and undamaged.

Red cat's-eye Scapolite crystal, complete all around and undamaged. The cat's-eye shimmer can be seen when held sideways under a light. These red crystals are rare to find and this is the best one I've ever had.

Bi-color Scapolite crystal that is half red and cat's-eye and half transparent and golden. Complete all around and undamaged except for one small nick on a termination edge. The cat's-eye shimmer can be seen when held sideways under a light. These red crystals are rare to find and this is only one of 3 I've ever had the chance to buy.

Complete and undamaged double-terminated Quartz crystal with inclusions of Graphite and Tsavorite. The Graphite occurs as 3 distinct platy crystals. The Tsavorite crystals are spread out inside the Quartz with one exposed at the surface. A Merelani rarity.

An exciting new specimen of tabular blue Apatite. From the Namalulu area, which in the past has produced elongated yellow Apatite. This is only the second one like it I have seen.

Single Diopside crystal adorned with gem like crystals of Tsavorite. Good Tsavorite on front and back. A small treasure.

Gem Tsavorite crystals to 9mm with Graphite.

Chrome Tremolite and gem blue Apatite crystals on a matrix of Calcite, Zeolites, and Graphite. I have previously only seen loose single crystals of Tremolite and Apatite from Merelani. Here you have a single matrix specimen with both species combined.

Mining for Spinels in Mahenge in 2016 has turned up a handful of these unusually colored single Apatite crystals. I bought every one I could, which was only 4. The color is blue with a hint of green and it's very gemmy. Undamaged.
