Bright, irridescent blue Covellite associated with Pyrite, Enargite crystals and Quartz. Beautiful specimen from a lesser known Butte Mine, the last and largest underground mine in the district.

Single transparent Quartz crystal with unusual form from the Mondo Mine. This recently discovered mine shot to fame for two reasons: 1) Quartz crystals of exceptional transparency and 2) a large variety of highly complex crystal forms including uncommon crystal faces, edge serations, and etched forms. This crystal is likely the result of etching followed by recrystallization resulting multiple angular indentions up and down the prism faces. Some of the original termination faces remain intact. Well crystallized all around, even the bottom, a real stunner! A strange one for a Quartz crystal collector.

Single transparent Quartz crystal with tapering form from the Mondo Mine. This recently discovered mine shot to fame for two reasons: 1) Quartz crystals of exceptional transparency and 2) a large variety of highly complex crystal forms including uncommon crystal faces, edge serations, and etched forms. Water-clear crystal with etching on most prism faces.

Glassy and gemmy pink Beryl crystal (Morganite) with an attached Tourmaline crystal. The Morganite crystal is undamaged and has a core of translucent Morganite with an outer zone of highly transparent Morganite. The change in clarity, somewhat like a phantom, is discernable in the first photo.

Colorful, vuggy specimen of Azurite on Limonite. The Lilyama Mine is an old Copper and Gold mine in California's Gold country, in fact it's close to Coloma, where Gold was first discovered in California. This mine has produced what is among the best Azurite found in California. Collected by Jay Buscio in the 1990s.

Specimen of solid fibrous, chatoyant Sugilite. Usually found as massive material, this is an uncommon example of solid fibrous, chatoyant Sugilite that displays a cats-eye effect when turned under light. Weighs 12.72 grams.

Cluster of large color-zoned purple/blue Fluorite crystals from Illinois. The cubic crystals are blue with an outer zone of purple and reach 5cm on edge. From old stock originally purchased from Ross Lillie decades ago.

Cluster of large color-zoned purple and blue Fluorite crystals from Illinois. A floater cluster well crystallized all around with attached red Sphalerite and Chalcopyrite. From old stock originally purchased from Ross Lillie decades ago. Two photos are backlit.

Cluster of stout, transparent Rose Quartz crystals from Brazil. This are unusually large, robust crystals with exceptional transparency. The main crystal is 3.5 x 2.5 cm in size and you can see straight through it!

Water-clear, highly complex etched Heliodor crystal. The surface is a mixture of sharp angular forms and smoother areas that show the interanl transparency. Complete all around an undamaged crystal that weighs 3.8 grams.
