Prismatic single Bastnasite crystal. Translucent to transparent with a rich golden brown color. Zagi Mountain Basnasites are by far the world's best, it's basically a one locality mineral and they won't last forever. 

Transparent blue/green double-terminated Vivianite crystal with attached radial crystals of Siderite. Complete all around and undamaged. This one has it all - great color, transparency, and double-terminated form which is uncommon.

Beautiful and glassy large magenta Roselite crystals lining a shallow vug. Robust crystals to 8mm in size that are lustrous and transparent. The color and quality of this specimen will light up and energize any mineral display.

Translucent, bright yellow Barite crystals over an earlier generation of white Barite. Well crystallized on both sides with strong, saturated yellow color and in great condition overall. These old German Barites are uncommon to find now. Comes with a number of old labels including the Lesnicks, the William Hiss collection, and Kristalle. A John Durkos label indicates it was purchased from the Lesnicks at the 1981 Franklin mineral show.

Large specimen of solid, intergrown Eosphorite crystals. The smaller terminated crystals on the front reach 2cm in size, and there are etched, partial crystals of Brazilianite on the back. These are huge crystals for the species, which are most commonly seen as tiny 1cm or so crystals on Rose Quartz. Collected by well known mineraologist Dick Gaines, likely in the late 1960s to early 1970s, a true connoisseurs specimen.

Cluster of large, scalenohedral Calcite crystals. These are beautiful, shimmering and transparent, some with the transparent crystals over a more translucent earlier generation of Calcite. Except for a tiny cleave on one tip, the entire cluster is complete all around and undamaged. Much better than photos!! A real jewel of  a specimen.

Beautiful large specimen of Dioptase on drusy Quartz over Chrysocolla and Malachite. This looks like something out of Africa rather than the USA, but it's old Arizona material with large isolated Dioptase crystals to 7mm in size. A big and colorful Arizona classic that will add pop to a mineral case.

Well defined, spikey 'spear point' Descloizite crystals covering a thin matrix. The central star cluster displays crystals sticking out in all directions and rainbow iridescence. Undamaged with much more character than most.

Deep yellow mounds of Mimetite partially covered by Calcite crystals from a lesser known Mexican Mine that produced these specimens decades ago (1950s). Some of the mounds show growth on top of more hexagonal, barrel-shaped crystals of the same color, distinctly Pyromorphite-like in form. There are also areas with black Plattnerite on the Mimetite.

Mounds of satiny pink Smithsonite from Choix. A beautiful uniform pink color with areas more purple near the top. Bi-color Smithsonite from this locality is uncommon. Undamaged with great sparkling luster.

Colorful specimen of drusy Dioptase over translucent Chrysocolla atop a black matrix. Old Arizona classic that is now hard to come by. Pristine.

Long, feathery crystal cluster of white Barite. A floater with no points of attachment. Elegant and beautiful specimen. A natural work of art.

Superb quality, lustrous Olivenite crystals grown atop the tips of milky white Quartz crystals. Individual Olivenite crystals reach 5mm in size. Rare, old time material seldom seen available for sale.
