Iridescent blue Covellite crystals on Pyrite crystals with a transparent Quartz crystal to add ever more flair. The Covellite form thin, bladed crystals and the color combination between the Covellite and Pyrite make this one heck of a showy Butte specimen. Ex. Randy Parnagian collection.

Single, gemmy fancy-colored Tanzanite crystal. This is an unusual color in my experience, with the front face showing a colorless center with pink edges and blue near the base. When viewed from the side, it's almost colorless. It's pink to yellow down the top (C-axis). Undamaged and water-clear.

Cluster of gemmy cherry-red Rhodochrosite crystals. An uncommon pineapple-shaped cluster that is circular in form when looking down on it from the top.

Scepter-like Quartz with an unusual spotted appearance. The outer layer of Quartz is colored red by Hematite and the lower portions were etched away leaving a red termination and scepter-like appearance. The red area is part dull maroon with lustrous lighter red spots. I got this from Marshall Sussman back in 2013 when most of the red and orange Hematite-included Quartz crystals were being found, and only a couple had this spotted appearance. Complete all around and undamaged.

Large, complete single Azurite crystal from the Milpillas Mine. This crystal appears to be from a small 2014 find where Azurite was found associated with Chalcocite (see my specimen M130). One side shows attached or included dark Chalcocite (?) along with small areas of vivid iridescent light blue. The whole crystal is complete and shows the bright 'electric' blue that is more common with some of the Milpillas Azurite. There is a bit of attached Quartz along the top edge, but otherwise this is well crystallized all around with good faces everywhere except the thin bottom side where it was attached. Undamaged, large crystal.

Fine quality tabular Azurite crystal on matrix of glassy colorless Barite crystals with spherical Malachite, which is characteristic of specimens from the Volborthite zone or pocket. The crystal glows translucent blue when backlit. A highly aesthetic full thumbnail that I've owned for many years, selected from hundreds of specimens after the April 2015 Volborthite find. Complete all around and undamaged.
