Rare Canary yellow Anglesite crystals on a Galena matrix. There are two main crystals to 2.2cm in length. The crystals are highly transparent and complete, with only a tiny nick on the top crystal. Small Cerussite crystals are present on the matrix. This color is very uncommon to find!

Beautiful Illinois Fluorite specimen with stepped cubic faces on the front and etched surfaces on the backside. Translucent deep purple color with a bright blue outer layer. Small Calcite crystals are attached to the backside.

Aesthetic cluster of large, elongated Dioptase crystals. Undamaged. This is from the Lou Schwartz collection and one of the earlier pieces found at the locality.

Large, elongated single Dioptase crystal. Undamaged, transparent to translucent with attached white Calcite around the base. Exceptional single thumbnail Dioptase.

Well isolated Dioptase crystals to 8mm on white rhombic Calcite crystals. There is a second generation of Plancheite (?) or possibly tiny Calcite atop the Dioptase crystals. The label indicates that the mineral on the Dioptase is Plancheite.

Rare blue Prehnite crystal cluster from the Merelani Tanzanite mines. The blue Prehnite from this locality is far less common than the yellow and displays a color change (two different shades of blue) in indoor versus outdoor lighting. The Prehnite is undamaged though there are some cleaves of Calcite on the left side. This is a great example I've held onto for about 10 years or so and also has small Sphalerite, Diopside, and even a bit of Tanzanite attached, along with the black Graphite.

White prisms of Calcite forming a crown atop metallic Stibnite crystals. The Calcite crystals cover the backside too. Old specimen purchased at least 20 years ago and held in my collection.

Translucent to transparent purple Fluorite cubes with attached Galena and Chalcopyrite. A beautiful, clean and undamaged specimen. The tiny Fluorite on the Galena crystal really adds to the beauty of this specimen.

Glassy blue and purple Fluorite cube with Mica and Quartz crystals combine to create a stunning miniature of high quality. This is an old specimen I've owned for 20 years or so. It's undamaged and a fine quality example from the mine, in this size range. I love the transparency of the main cube and the additional tiny Fluorite cubes attached to the matrix.

Glassy and gemmy Dioptase crystals on white rhombic Calcite crystals. There are crystals on both sides of the specimen and on the edges you can see Duftite in the matrix. There is also a partial Wulfenite crystal. Color, classic Tsumeb specimen.
