Spectacular cluster of Quartz var. Citrine crystals with Scepter tipped terminations!
This is an incredible display specimen and it can be displayed in a myriad of ways due to the
positioning of the large scepter-tipped crystals. One thing I want to point out is that this is not
a small specimen. It is borderline large cabinet with the main center crystal measuring nearly
18 cm in length. The crystals are included by a green mineral, probably Chlorite, along the lower
right edge, before changing over to a beautiful deep orange along their lengths. The crystals then
terminate with colorless scepters. The surfaces of the crystals are textured by hundreds of small
faces which reflect the light and create an intense sparkle. The scepters are smooth and glassy.
This is a superb Quartz specimen from a recent find and it is in excellent condition, top to bottom.

Large, translucent Calcite crystals perched atop Quartz crystal matrix!

these detract from the specimen. The crystals are glassy and tranlucent with pearl-like brilliance.

**Tremendous plate featuring fine dendrites of Native Silver with Acanthite and Safflorite accenting! This is a wonderful display piece from the classic Cobalt Mining District and is literally covered from one end to the other with large dendritic structures of Native Silver. A peppering of grey Safflorite covers much of the dendrites as does Acanthite drusy. This is incredible rich specimen and the display is beautifully presented atop white Calcite covered surface.
