A beautiful specimen hosting sharp black babingtonite crystals with light green prehnite on Quartz points. It's a 'floater' with no apparent point of attachment and no visible damage to any of the species. This example is in pristine condition and is as superb classic from this Chinese locality.

This specimen has water-clear fluorite crystals positioned on massive white calcite. A few grey-black galena crystals and some very minor micro pyrite crystals are also in association. The calcite surfaces are smooth showing some evidence of etching. Ex. Frazier's Minerals.

Here's an old English classic that features a large 1.8cm 'ball' of tan color Siderite crystals on a contrasting darker matrix of Cookeite from Cornwall. A very clean, aesthetic old-timer with numerous provenance labels including William Severance, Carter Rich, and Arnold Fisher. An old Trinity Minerals label shows a price of $300.

A display specimen of white Calcite crystals hosting a few dark black Hematite crystal groups from this classic locality. An older example from The Charlie Key Collection disbursed a number of years ago. One old label shows a former price of $600. Lots of lustrous, clear and undamaged Calcite crystals and I can only find a couple missing along the back edge.

Milpillas has produced some of the most beautiful Azurite specimens in recent time. Here's 3-dimensional cabinet size matrix specimen with dark, highly lustrous, blue crystals. The Azurite actually covers the top of the matrix and crystals grew over the edge on one side. The opposite side shows green Malachite coverage. Only very minor contact to the Azurite crystals, most of which is natural wall contact. An excellent example.

Group of Copper crystals coated by Cuprite. The Cuprite covers most of the surface of the Copper and is crystallized in areas. There is also black Heterogenite and green Malachite present in areas. Large and colorful Copper specimen found in 2018.
