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.

Terminated clear Quartz crystal with a light 'dusting' of small light green Chlorite balls and several light purple Fluorite crystals. The Fluorite crystal near the top is incomplete. Still an aesthetic combination of species from the locality. Ex. A. L. McGuinness Collection.

A flat plate of pink color scalenohedral Cobaltian Calcite crystals are host to a botryoidal mound of fibrous green Malachite crystals. Damage to a few of the Calcite crystals but without it you could add another zero to the price, at least. These are rare and those with the visual pop added by the Malachite are very rare.

Rich pink color Cobaltian Calcite crystals to 15mm in size. Although there are a couple bruised crystals, this is a high quality Cobaltian Calcite with bright color and translucent to transparent crystals.

A miniature size specimen of Enargite with several well-terminated silver-black crystals from Butte, Montana, known as 'The Richest Hill on Earth'. These mines have not produced for decades.

Deep purple, satin finish octahedral Fluorite crystals are seen intermixed with an earlier generation of green Fluorite crystals. These are New Mexico classics and the shown here is an exceptional example with no damage to the main crystals. Largest purple octahedral crystal is 2.1cm on edge.

A plate of thin, dark color matrix hosts a cluster of clear, sharply terminated rhombohedral Calcite crystals and a small amount of green Duftite. An older Tsumeb classic with no damage to the Calcite crystals. Ex. Collection of Tom and Gale Parker. Excellent Tsumeb Calcite specimen.

Most of the Boleite specimens from Amelia Mine were detached from the soft clay-like matrix. This specimen a rare example of one that still has Boleite crystals intact and in stable condition on the original matrix. There are at least a dozen blue Boleite crystals with the larger ones measuring about 4mm wide.

Turquoise in matrix from historic Bisbee, Arizona. The Turquoise was located in the conglomerate rock atop the main Copper ore deposits that was removed as overburden. Most the Bisbee Turquoise was therefore recovered in the mine dumps in the 1950s and 1960s and are now uncommon. The specimen comes mounted in an old 2 inch x 2 inch plastic box with label. It has one sawn flat surface to show the sky-blue Turquoise.

It appears to have been stabilized.
