Crystallized turquise is for some reason a true rarity in nature and occurs only at a VERY few localities worldwide. This one, in Virginia, is the most famous of them. While the crystals individually are sub-mm, this piece overall has an incredibly rich and pristine coverage area that is loaded with them, making it an important specimen.


MRZ139 - Woodhouseite on Quartz - SOLD

Sharp woodhouseite crystals to 4 mm or so drape all over the quartz points here, makig nthis both a significantly rich and a beautiful specimen. I have seldom seen such good examples larger than a thumbnail, of this rare species named after the noted mineralogist Woodhouse. The mine is now close dand defunct, and this material is impossible to find easily on the market. As this is a large and somewhat showy piece, I attach value to it beyond just as a representative of the species.

Interesting specimen of "mountain leather", a decrepitated claylike mineral that has the feel and sturdiness of cardboard.

Sharp, deepest-azure-blue crystals of lazulite on quartz - the classic association from this locality! The lazulite crystals are mostly around 5-6mm.

Lustrous, transparent, GEMMY eosphorite crystals to 7mm lierally coat this elongated quartz shard. This is a very high quality specimen from famous finds of the 1980s, still the best quality if you like lustre and transparency in this species.


MRZ253 - Eosphorite and Zanazziite on Rose Quartz - SOLD

A very attractive combo specimen with sharp and GEMMY eosphorite crystals, unusually well isolated on matrix, to 1 cm in size. This is highly unusual for the habit! The small green spheres were identified as kidwellite but are more probably the species zanazziite, though I have not XRAYed to be sure.

A very sharp miniature featuring a cluster of sulfides about its center, lapping up against a gemmy quartz point. The arsenopyrite is on the left, the stannite on the right, in crystals to just over 1 cm . The quartz has a tiny ding, which is why I have lowered the price below the Zinn appraisal price of $400.

Gemmy, pastel green, datolite crystals, to 2 cm across, are associated with truly unusual quartz crystals. The quartz crystals, to 6 cm in length, exhibit what might be milky overgrowths which give way to gemmy, "poker chip" development said to result from intergrowth with calcite that i snow dissolved and gone. These are BIZARRE specimens! I have not seen one in a decade, and they seldom turn up now. The unusual form as well as the association make this specimen a special piece. Not sure why it was passed on to me in the rarities suite, but there ya have it....

A 7.0 cm tall quartz stalactite of sparkling, snow white, drusy quartz, is the host for a few crystals of pearlescent barrerite, to 3.75 cm in length, a rare member of the zeolite family. Rarer still, this was from a one time discovery in Alaska. I recall when they came out, and a single dealer had a table or two full of them at one of the hotel mineral shows run by Marty Zinn. Superb!

A colorless, transparent, and lustrous crystal of quartz is heavily included with golden, 2mm across, transparent GEM crystals of anatase. This is far more beautiful and much rarer than the rutile inclusions one regularly sees in quartz. The very tip of the quartz termination has just the smallest hint of edge wear when seen from teh side - However, it is inconsequential to this exquisite piece. It is a superb display specimen and the inclusions are readily visible.

A transparent, incredibly lustrous, quartz crystal, has grown around the thickest blades of golden rutile I have ever seen included in quartz of this size. The quartz crystal measures 6.5 cm in length and is super-gemmy and clear, with internal brightness. The blades of rutile appear to display chatoyancy and are themselves of high lustre, the best quality. On top of all this, the specimen is on matrix. The back side of the piece is contacted, but this is of no cosequence. Because of the sharp termination, the incredible lustre on both species, the high quality of both species, and the shocking combination they make, I believe this is the best specimen I have seen of this combination I have ever seen in a miniature/small cab size range. It is expensive because the guy I got it from, also knew this. But, for all that the price is higher than i would prefer to have to charge, its worth it for the superlative quality.

Two, transparent, lustrous, and colorless, quartz crystals, to 4.5 cm in length, are include by gemmy, golden anatase crystals, to .5 cm across. In fact, there is an superb, unincluded, doubly terminated, GEMMY, golden crystal of anatase at the base of the quartz crystals which measures .8 across. STUNNING and rare combination!

From the same locality of Diamantina, is another transparent, colorless, and lustrous quartz crystal, this time acting as the host for gemmy red garnet crystals, to .3 cm across. Minor edge and termination wear is evident on the quartz, but, once again takes a back seat to the rarity of this occurrence.

An incredibly rare, rich example of scheelite from this classic locality best kown for cassiterite , as long ago as 250 years. I have seen small, ugly, insignificant scheelite specimens in the past but none of this magnitude, and with such good documentation and pedigree in any case. It is much prettier in person, by the way. Note the old labels....he acquired this personally from Sir Russell who in turn acquired it from the collection of H.F. Collins (as noted on the Russell label included)

Aesthetically nestled in a bed of colorless, transparent quartz crystals, to 3.0 cm in length, are several parallelhubnerite crystals: dark red, with bright red, gemmy, highlights. I have never seen such thick AND gemmy hubnerites and the contrast with the stark white quartz is incredible. This is a VERY choice piece that came out in the 1980s and has long been in a private German collection. The lustre, color, sharpness of the crystals is superb. It is nice that they have REAL terminations instead of the usual fuzzy-terminated style from the locality where the terminations just sort of taper off. Here, we have lustrous, chisel-shaped faces. The largest hubnerite crystal measures over 5.0 cm in length. The color and crystal contrast, again, is just MUCH BETTER IN PERSON to the point i guarantee you won't even believe its the same piece when you hold it in good lighting, compared even to these nice pics.
