THE VAULT

An exquisite emerald specimen, simply "different" to my eye than so many others. It has a very castellated, complex multiple termination that to me looks like towers out of a fantasy movie made of gemmy green emerald. The color is a vivid, bright hue. Some collectors prefer darker colors, some li... Click For More Information

A spectacular tree-like, thick and robust crystallized gold from this important modern-era find from a few years ago. The first golds were actually imported as lapidary and gem material, and now it is not possible to export specimens, or to mine new ones as the zone is under control of a large go...

From old finds of the 1990s that really surprised the mineral world, these gorgeous elongated gold crystals perched on quartz plates have not been seen in ages. This is an old specimen that I handled in the late 1990s, and came back to me. It is one I always remembered for the simple elegance, as... Click For More Information

A large, and significant crystal for this very rare gemstone species, a neon pink-red Pezzottaite from the type locality in Madagascar. This is a superb, complete, tabular hexagonal Pezzottaite crystal with well-developed, broad, flat terminations modified around the edges by complex modification... Click For More Information

From the late 1970s, this is a very rare and desirable style of rhodochrosite we called "shields" in habit, that have never been found again since. The crystals feature a "flattish habit with a dominant pinacoid" according to the article in the 1978 issue of Mineralogical Record when the discover... Click For More Information

Even after all the other historical localities (Tsumeb, Russia, etc.), there is still something about these elongated dioptase crystals from modern finds in Northern Namibia by Charlie Key (keyite, ludlockite, and the Indiana Jones of mineral collecting in Southern Africa) and his mining team tha...

Scheelite from this now-diminished mine near the famous Panda Preserve in China simply is, beyond any question, the gold standard for the species. I have followed these for 20 years, since the mid-1990s, and they got better for awhile and then tapered off suddenly after the big earthquake of 2008... Click For More Information

Milpilas flowed azurite, and then flowed some more when we thought the oxidation zone would not give up more (watercourse pocket going down into the oxidized orebody), and then finally came to a crashing end for supply of the worl'ds best and most prolific azurite finds in all of history. Neverthele... Click For More Information

Pentagonite is the much more rare cousin of cavansite, technically a "dimorph" which means that it is the same chemistry but a different crystal habit, and therefore a different species. The color is equally good, but the sparkly luster on pentagonites at their best is better than most cavansite. Th... Click For More Information

The number of Colorado rhodochrosite specimens combined with fine fluorite of any quality can probably be counted on two hands. The number of cabinet sized examples, is probably half a dozen in all time. This large, fine, gorgeous plate has no repair or restoration unlike many others. It shows off a...
