This unusual combination specimen features clusters of 1-cm crystals of white calcite and colorless quartz contrasting with several splendent, black, ilvaite crystals to about 1 inch. All of this sits on a matrix of massive hedenbergite (sawed flat on the bottom to stand). All of the upright, major ilvaite crystals are fully and magnificently terminated, with the only damage confined to the periphery and thus to the less significant sideways-pointing crystals at the base. Ilvaites of this quality came out richly in the late 80s and the 90s but have since completely evaporated from teh market. Now a Russian classic!

Looking very much like cactus growth, this ELEGANT calcite specimen features translucent, hematite included crystals to 7 cm in length. In addition, the piece exhibits chocolate brown color and the high luster that make the find unique. Old material, from the late 1980s - I remember as i owned one when i was a kid and they were coming out.

Herringbone-style silver from Batopilas is one of the classic examples of crystallized silver in collections. They form from intergrown, sharply elongated spinel twins, connected together. When these silver specimen were plentiful in the late 1970’s, this would still have been a quality piece with unique aesthetics. Today, they are much harder to find and large specimens in particular are uncommon on the market though little cheapies still trickle in from time to time. The specimen is capped off by two 8 cm vertical crystals - that is 3 inches of crysatllized, spinel-twinned silver!
Only a very few specimens in this pocket seem to have caught the nearby hematite crystals, and come out in association. This piece is dramatic! It features a doubly-terminated 4.4-cm crystal, inset with a small cluster of glistening jet black hausmannite, ON the hematite-covered plate. On the other side, it is covered by soft white oyelite, so either side offers great contrast for the display of the specimen. The hematites, to 1.7 cm, are mirror-bright, so shiny and reflective you can shave in them. This is a unique piece from a unique pocket, with singular aesthetics.

A really dramatic large piece of classic Tsumeb stacked rhombohedra! They ar elightly speckled with a black mineral I forget the name of, but it occurs often with this habit. The complex, stacked visual effect of the crystals is classic for Tsumeb!

We call this the "ice cream" pocket for obvious reasons. This is a VERY choice specimen from this one famous pocket of calcite with included copper, that gives it a wonderful pastel green hue unique to my knowledge. The surface looks like sugar, brilliant and sparkly ! This is not a true species per se, but rather a varietal of calcite. Nevertheless, it is unusual stuff from a one-time find , and extremely attractive in any case. They glitter like you won't believe. This is a large one! I am told these came out in the mid-1980s

This oddball is a cast formed as a thin layer of (sturdy!) cobaltian dolomite coated an existing plate of rhombohedral calcite crystals. The calcites then dissolved away, leaving this cast plate with both positive and negative sides showing!

A gorgeous radial cluster of traditional Tsumeby-style rhombohedra, that are almost curved with extra faces, and attractively dusted by included specks of red hematite grains. Good lustre, excellent transparency into the crystals, and overall just VERY PRETTY! and, unique to Tsumeb

A supremely aesthetic and unusual Tsumeb piece with a perfect rosette of calcite, complete, perched nicely on primary malachite crystals! In person, the deep green of the malachite is more readily apparent

A gorgeous miniature dioptas,e that doesn't break the bank: this specimen features a main crystal 1.7 cm long and 1 cm thick! It has TOP color, lustre, and is just much better in person than it appears, as with all dioptase in photos.

A really beautiful calcite because of the clarity of the water-clear calcite on top of the green mottramite-coated matrix. It is stunning! The smaller calcite, in front, is 3 cm across. It has minor edge wear on the bottom but this does not detract at all , visually. The upper crystal shooting up from teh top of the piece is to 3 cm on edge, or 4.5 cm across longways. It is complete on the front and all around the sides, contacted slightly on the backside only. This piece is in incredible display piece and shows off dramatically - MUCH better in person.

A very cute toenail-sized specimen featuring a perfect, sharp, gemmy, lustrous dioptase perched atop a complete calcite rhomb! Stunning contrast!
A beautiful combo piece of bright white calcite covered with a second generation of sparklier , minutely-crystallized calcite, perched on bright jet-black sphalerite crystals. VERY sparkly and colorful overall for a black-and-white piece. Small, gemmy, transparent cuboctohedral fluorites sprinkle the calcite at its tip and are scattered about the matrix as well. I am told that not many of these came out with the main pocket of fluorites.
This unusual Naica piece is more starkly octohedral than others you normally see from the locale. It is actually the only OLDER specimen slipped into this update of newer material. It dates from , probably, the early 1980s. The piece has two large octos in the middle, coated in front by a blanket of dogtooth calcites. The contrast is very nice! The octos have SLIGHT cubic modifications, you can see, at their very tips. But they are still more octo than cube by far and as such are the exception at Naica.
This is an elegant cluster of floating calcites with incredibly glassy lustre, from the mid-to-late 1800s mining at Egremont for iron. It is complete all around and has very sculptural aesthetics, making this among my favorites for the size and price range that I have seen for the material. This has long been in the collection of my friend here in Dallas, Wally Mann. It look slike a smaller version to the famous example from the same region that Bill Larson has used in advertising for his business, for decades. I traded this from Wally for my own collection some years ago.
