On a matrix of white masive garnet are perched two glassy and gemmy, olive to cognac-colored crystals of topazolite to 2 cm across. This is a rare and excellent size for the species. Both crystals are doubly terminated and both exhibit small regions of unusual, incipient hopper growth. Members of the garnet family, other than this find, rarely show this growth pattern. Aesthetically isolated on contrasting matrix, this is an excellent topazolite from any locality - but would be hard to find in this quality elsewhere, from previous finds. Perhaps more than the demantoids (which cost a lot more and are highly valued for sheer color pizzazz), this locale will be remembered for its topazolite.
A matrix of limestone metasomatized to massive garnet is host to a single glassy and gemmy, rich, cognac-colored crystal of topazolite. The crystal, lying flat on the matrix, is doubly terminated, 1.5 cm across, and is a rare, perfect, isolated gem crystal ! It has a few very small zones of slightly inward-hoppered growth, which is unusual and interesting. It has superb lustre, and transparency. You can look right through it to the matrix beneath! This is actually a miniature (large) when set up diagonally.
This unusual and lovely demantoid specimen hosts glassy and gemmy, light emerald-green crystals, to 1 cm across, emplaced on a sugary, massive garnet matrix. The matrix is actually sparkly, itself. Growing on the matrix and among the garnet crystals are lustrous, white crystals of stilbite, to nearly 1 cm in size. This is one of only 3 specimens in this lot that have associated stilbite. Stilbite is not only just a rarity for this deposit, it is an extreme rarity in association with garnet from ANY locale and serves to highlight the bizarre geology of this deposit. From my understanding of things, there is still not a very good explanation for how the stilbite got here. Overall this is a fine, display quality miniature with subtle unique qualities, and the contrast to the white stilbite is one of those bonuses.
This is a solid plate of glassy crystals with INTENSE color! Most garnets from here do not form in such tight carpets of fine crystals. They tend to be more dispersed across the matrix. Some people like isolated crystals, and others like "flash" and density , which is exemplified in this specimen. The glassy lustre combined with strong color pretty much blow away most other demantoid specimens from other locales, and it ranks high for this locality as well. The massive garnet matrix is slightly concave, and is completely smothered by these briliantly glssy crystals of demantoid, to 1.2 cm across. A few crystals are doubly terminated; and a few also exhibit clear evidence of hopper growth, a rarity in the garnet family of minerals. Overall this is one of the most densely covered and flashiest specimens I have been able to obtain from the finds here.
A beautiful specimen that leaps out at you, with riveting color! This is a cluster of glassy and gemmy, deep-glowing-green demantoid crystals, to 1 cm across. The garnet spread, in 3 dimensions, contrasts nicely with the whitish, massive garnet matrix. The largest crystal exhibits incipient hopper growth, rarely seen in the garnet family of minerals. Overall, this specimen has a good 3-dimensionaliy and even a bit of a curve to it, and is much more impressive in person. It is one of our favorites in the lot.
Rich, cognac colored crystals of glassy and gemmy topazolite, to 1.7 cm across, are widely scattered on a matrix of limestone, metasomatized to massive garnet. Topazolite is a rare variety of andradite garnet, and this specimen hosts what surely must be among the larger crystals of the species. Several crystals are doubly terminated and a few exhibit clear evidence of hopper growth (unusual in garnets) - what appears to be a spot of damage in the photo, on the smallet of the 4 major crystals in the top cluster, is actually this strange, inward-hopperig growth pattern. Dr. Federico Pezzotta, on obtaining the majority control of the garnet production here back in 2008, has gotten to see more than anybody of the breadth of the find. This particular specimen is the one used in his slideshow at the Tucson 2010 show, to illustrate the highest quality of the topazolite crystals from this mine. He specifically pointed out that he considers this specimen to be the top, or at least among the top few specimens, of topazolite from this mine. Since these are apparently the world's best topazolites, for overall size and quality, that is high praise indeed.
A limestone, metasomatized to massive garnet matrix, is host to sharp and isolated, glassy and gemmy, light emerald-green crystals of demantoid, to 1.2 cm across. The large crystal is also doubly terminated. For perfection of form, and gemmy crystals of high quality as a representative piece from the find, a superb example
One of my personal favorites in the lot, this is a particularly elegant clustre on matrix, isolated, and with a stunning dominant crystal atop. This appealing demantoid specimen is composed of seven glassy and gemmy, richly green crystals to 1.5 cm across. The color and form of the crystals contrasts superbly with the underlying, white, massive garnet matrix (the matrix having been metamorphosed geologically from limestone to garnet, itself). Few specimens here, even those with more garnet, leap out to the eye a smuch as this, for the stark contrast and the top color. The main crystal here is so gemmy that you can really look right through it to the underlaying matrix, clear as day!
Unusually isolated and discrete, equant, crystals of transparent greass-green demantoid, to 1 cm across, are perched high on a contrasting massive garnet matrix (the matrix having once been limestone, now itself metamorphosed to garnet). These crystals are sharp, and gemmy, though have medium lustre. They are so sharply formed , though, that they look carved in their textbook symmetries. And, overall, this is a great example from the finds for the price and size rage, trading a little bit on lustre to get the quality of form and isolation aesthetics.
Perched high on contrasting white matrix, are discrete crystals of glassy and gemmy, beautiful green demantoid. The equant crystals reach 1.5 cm across and most are superbly isolated, showing all faces. This is one of the better matrix specimens for the size and price range, with top , very green color and good crystal size. There is no damage, and all crystals are very 3-dimensional! The contrast to the stark white matrix is very appealing and dramatic on this specimen. The matrix is limestone, metamorphosed geologically to garnet (yes: garnet on garnet...)
Aesthetically nestled in vugs in the massive garnet matrix are equant, glassy and gemmy, light green demantoid crystals, to 1 cm across. There are 4 major crystals and many minor, with the large ones really popping out 3-dimensionally. The quality is outstanding - they are deeply colored, gemmy, and lustrous. However the matrix could probably use some trimming to make it more aesthetic, I admit...making it a bargain, "as is" if you like big isolated crystals on display-sized specimens. (and if it doesn't sell, there IS a miniature in here that is worth more than prepped, with a little risk in the trim job).
A ribbon effect of heavily striated, glassy and gemmy, crystals of olive-green to cognac-colored topazolite are emplaced on a metasomatized garnet matrix (limestone metamorphosed to garnet) . The crystals reach 1.5 cm across, although the huge crystal on the far left, which initially looks like it has damage, is actually crystallized in a weird manner and is nearly an inch across. This specimen is a dramatic, distinctive and major example of this rare garnet gem species!
On a thin septae of matrix,is a cluster of equant, glassy and gemmy, olive-green colored demantoid, in crystals to 1 cm. VERY gemmy, very bright, this robust thumbnail specimen has a high quality and sits nicely. It has many facets reflecting light, so shows off more nicely than you might expect at first.
Aesthetically nestled in a vug of garnet matrix are a few, discrete, nearly limpid jewel-like crystals of the highest gemminess and brightness: glassy and gemmy, richly green demantoid crystals, to 6 mm. While not the biggest crystals, this is a stunning example representing the best quality of this find in the garnets !
One of our favorites! This is like a cluster of green jewels, all linked together. It is a floater specimen where the crystals are on a strip of matrix, that is also crystallized around the back. The display face is covered with a continuous, sparkling cluster of glassy and gemmy, light emerald-colored demantoid crystals, to 1.2 cm. They have sharp form, good lustre, an dgood color...but the overall aesthetics of this is more, and it makes for a striking miniature.
