Light purple color Fluorite crystals are embedded in a matrix covered with white druze Calcite crystals. Multiple zones of color can seen in the Fluorite cystals ranging from internal light yellow to purple at the outermost edges. No damage to the two main Fluorite crystals.

A cluster of light purple color-zoned Fluorite crystals in white matrix. The internal pale yellow color transitions to purple at the outermost edges. No damage to the main Fluorite crystals.

A beautiful combination of large amber color Fluorite crystals with a few lighter purple color-zoned crystals and translucent white Calcite crystals. The specimen is in superb condition with a cleavage on one corner, otherwise no damage to any of the main crystals. An American Classic specimen.

Flattened rhombic crystals of white Calcite cover the main faces of a large purple Fluorite crystal measuring 8cm on edge in very clean condition. Only minor chipping to some of the Calcite crystals.

Shimmering gray botryoidal mounds of Smithsonite in typical brown, gossan-like matrix from the famous Magdalena District. Kelly Mine is most well known for producing high quality 'Kelly Blue' Smithsonite specimens, but the Graphic Mine in the same complex also produced stellar specimens in both colors. A beautiful specimen with no damage and an old collection number painted on bottom.

Transparent light purple cubes of Fluorite on white Baryte crystal blades. A classic and desirable combination that is now hard to find. All of the Fluorite crystals have razon-sharp edges and are damage-free.

Benitoite crystals were occasionally found as 'floaters' that had weathered out of the host crossite amphibole rock matrix. This is an example of a single large crystal with blue-gray color and a rough surface caused by the amphibole inclusions. Even though it's not dark blue in color, it does have the same 'cornflower blue' fluorescent color when seen under shortwave UV lighting.

Some of the finest known examples of Pyromorphite come from The Bunker Hill Mine. Specimens were collected in a multitude of colors, mainly within the orange, yellow, and green spectrum. This example shows elongated crystals with greenish-yellow color and high lustre.

Some of the finest known examples of Pyromorphite come from The Bunker Hill Mine. Specimens were collected in a multitude of colors, mainly within the orange, yellow, and green spectrum. This example shows crystals with orange and tan color and high lustre. Contact to some of the crystals on the backside.

A fan-shaped group of dark blue color Indicolite crystals (variety of Tourmaline) with two small clear Quartz crystals. A couple of the Indicolite crystals broke off naturally in the pocket during formation (as evidenced by the Quartz crystal grown atop one of these breaks). Great color.

A 4mm transparent white Diamond crystal in a typical rounded Kimberlite matrix. These matrix pieces are very rare now (there never were many of the matrix pieces available). Comes with an old Al McGuinness label.

Dioptase crystals to 11mm on white Calcite crystals. Slight damage to the upper left crystal, otherwise undamaged specimen. Showy specimen with sharp terminated crystals which highlight the color contrast between the Dioptase and Calcite.

A beautiful combination of white Baryte crystal rosettes evenly distributed on dark purple cube-shaped Fluorite crystals over yellow Fluorite. The specimen is in superb condition with no damage to any of the main crystals of either species. An American classic specimen.

A gemmy, complex Cassiterite crystal with glassy faces and overall smoky black color. A small bit of white matrix remains on the bottom, otherwise a floater. Excellent Chinese specimen, slight edge chipping otherwise undamaged. Good transparency. Ex. Debbie Meng's Minerals.

Blue Azurite crystals in the center of a crystal rosette with green Malachite pseudomorphs after Azurite in the outer portion of a cluster. Floater specimen of fan-shaped crystals of good quality. Excellent all around with no damage.
