Snow-white Barite blades, with some that are amber colored, over a matrix coated by drusy Sphalerite.This is out of an old collection built in the 60s and 70s and is surprisingly clean and undamaged, good from both sides. 

Large cubes of lustrous Galena crystals, to 5.2cm on the diagonal, on matrix associated with Chalcopyrite and Calcite crystals. Such specimens with good large crystals on matrix are no longer common.

Elongated Pyrite groups that have replaced a previous mineral, possibly Calcite, on a matrix covered by Sphalerite. The base of one of the Pyrite crystal groups is visible and whatever was there before is all gone now - nothing but solid Pyrite. Bright, shiny luster and undamaged.

Well formed large Ferberite crystals associated wtih transparent Quartz crystals. There are also small purple Fluorite crystals, Muscovite, and Arsenopyrite present.

Color-zoned purple/blue Fluorite cube with 5 terminated Quartz crystals grown along the sides. Two small trivial nicks otherwise pristine. Wonderful transparency and aesthetics.

Cluster of translucent yellow Prehnite crystals on Graphite. Such yellow Prehnites have come from Merelani sporadically over the years, but never before in the quality that has been found in the last year. This specimen has big chunky crystals all over in a tall mound shaped formation. There is some chipping present, but mostly nothing but great crystals sticking out 360 degrees in all directions. A good one for the find.

Exquisite jewel of a Carrollite set perfectly in rhombic white Calcite. The octahedron is 1.1cm in size, highly lustrous, and undamaged.

Single crystal of Chrome Tourmaline, a vanadium rich Uvite/Dravite. Deep emerald green color and highly transluscent to transparent when backlit. Undamaged crystal 0f superb color!!!
