Vein of white Calcite loaded with crytalline Silver with lots of exposed Silver crystals on top. The Silver is present all throughout the Calcite, top to bottom. Out of an old collection from the 1970s.

Old specimen of red Inesite in radial crystals groups on matrix of Xonotlite, with minor amounts of Calcite. Free of damage, fine specimen.

Deep purple blue Tanzanite crystal perched atop a matrix of Tanzanite, Calcite, and Graphite. The Tanzanite is translucent with a jagged termination, and is undamaged. A fine, showy matrix Tanzanite that won't break the bank.

Along with many other 'world's best of species', Merelani produces the world's best Prehnites (in my opinion). This fantastic specimen is a complete undamaged floater that looks like it was constructed by dropping little grains of Prehnite atop each other until they formed this tall stack of crystals. The rear bottom is black from inclusions of Graphite, and there are Laumontite crystals included on one side near the base. One of the best Merelani yellow Prehnites I've owned.

Orange Wulfenite crystals on Calcite coated by Desclosite. The Wulfenite reach 2cm in size and have great color and luster. There are two broken off crystals, but all the remaining crystals are undamaged. Highly showy display specimen.

A fossil bivalve shell that has been completely replaced by pink Rhodochrosite. The shell is wonderfully preserved with both sides present and in perfect condition. One end has been cut to reveal the bubbly pink Rhodochrosite inside.

The beautiful Fluorites produced by The Elmwood Mine are American Classics. Here is a wonderful example with a group of light purple Fluorite crystals topped with white Barite and several double terminated clear Calcite crystals. The bottom matrix consists of amber color Sphalerite.

The beautiful Sphalerite crystals produced by The Elmwood Mine in Tennessee are American Classics. Here is a wonderful example with a cluster of gemmy Sphalerite crystals on a druzy Quartz and Calcite covered matrix. Contact to one crystal, otherwise near perfect.
