Large, chunky Hematite crystal with an uncommon psuedocubic form. Great luster with parallel surface striations. This is an old specimen from a collection dating back to the 60s and 70s. It came without precise locality information, but I suspect it is from the Casa de Pedra mine in Congonhas, Minas Gerais. It's complete all around with some indentations from other crystals on top near the back, but remarkably pristine with only a couple small nicks. Even the bottom is rehealed. Weighs 2 pounds and 14 ounces!

Two interpenetrating transparent Fluorite cubes with rich purple color. In great condition with good luster. Main crystal is 6.2cm on the diagonal.

Snow-white Barite blades, with some amber colored, over a matrix coated by drusy Sphalerite.This is out of an old collection built in the 60s and 70s and no further locality information was available. Clean and undamaged, good from both sides.

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, and unfortunately there was no  locality information available. I believe it to be from an old, lost locality in Riverside Co. It occurs with Chlorite and appears to have been partially etched from carbonate rock. It rates as a significant California Spinel. Undamaged.

Small Calcite crystals atop crystalline Copper with good patina. Calcite and green Epidote on the backside.

Cluster of translucent yellow Prehnite crystals. 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, nothing but great crystals sticking out in various directions. A good one for the find.
