Complete single crystal of Spessartine with the classic mandarin orange color. Spessartine from Marienfluss are rare to find and desirable. This crystal has some contacts but is complete.

Intergrown pair of Andradite crystals to 1cm perched strikingly atop matrix with Diopside and other Andradite. The top crystals are perfect and can be viewed 360 degrees all around.

classic deep green Cuprian Adamite with a couple small Wulfenite crystals. Clean and damage free.

A real GEM of a Tsavorite crystal. Totally transparent and crystalized on all sides, even the bottom. Some Tsavorites grow perched atop the edges of Graphite crystals which allows crystal faces to form on the bottom as well as the top and sides.There are residual thin black grooves on the bottom where the Graphite crystals were, otherwise fully crystallized.

Fine quality elongated Tsavorite crystal from recent production (2017) that has been producing these stange, elongated crystals. Many of the new crystals, like this one, exhibit a faden line running up the C-axis. This is an undamaged floater cluster of two interconnected crystals. There is also a tiny blue Apatite on the very tip, and another whitish etched crystal on one side.

Bright green Chromium Grossular cluster with largest crystal 1.1cm wide. Great luster, color, and transparency. Ex. Charlie Key.

Double terminated floater crystal with purple core and green/yellow terminations. Although it has lighter purple color than most, the central area has good transparency, which is uncommon. Ex. Charlie Key.

Double terminated floater crystal with purple core and green/yellow terminations. Ex. Charlie Key.

Three interconnected, curving and lustrous Prehnite crystals. Although many other localities produce good Prehnite, they are usually in rounded clusters or platy masses, not distinct individual crystals such as this. Nowhere, to my knowledge, produces as good crystals as those found at the Jeffrey Mine, but they are not well known because there just aren't many available, in fact this is only the second one I have owned. Ex. Charlie Key.

Bright green Chromium Grossular cluster with largest crystal 1.2cm wide. The very outer layer has an orange coloration. Great luster, color, and transparency. Back side of main crystal is indented where another crystal grew, but is not damaged. Ex. Charlie Key.

Cluster of Vesuvianite crystals with purple core and green/yellow terminations. Many are double terminated. Ex. Charlie Key.

Grossular cluster with largest crystal 1.3cm in diameter and almost perfect all around (one small indentation from another crystal). Great luster and classic cinnamon orange color. Ex. Charlie Key.

Deep, richly colored orange Grossular crystals on matrix with largest crystal 1.4cm wide. There is one small nick on the main crystal, but it was so nice I bought it anyways. Great luster, color, and transparency. Ex. Charlie Key.

Floater cluster of the rare pink Grossular crystals. Undamaged and complete all around. The pinks are some the rarest that were found at the mine, and I've never seen a floater cluster like this before. Great luster, color, and transparency. Ex. Charlie Key.
