Cluster of double-terminated Quartz crystals known as 'Herkimer Diamonds'. Bright and glassy crystals that are complete and undamaged all around.

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.

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

Large 3cm black Spinel crystal on matrix with other smaller Spinel crystals. This is an old specimen from a collection from the 1960s and 70s. It occurs with Chlorite and appears to have been partially etched from carbonate rock. It rates as a significant California Spinel. Undamaged.

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.
