The holy grail of mineral collecting is also a high sought after collector's gem! And this is one of the largest gems of this rare species that we have seen on the market, with certainly only a few larger in institutional and major private collections. It shows the unique light, bluish green color and saturation, that only phosphophyllites from the old finds of the 1940s-1950s have. A small amount of modern material from new find shere, cannot compete. These are spectacular stones for the species and are highly recommended for top collections both for the beauty and for their proven investment ppotential over time. That said, clean and gemmy stones tend to be very small. This is why our two gems are important standouts. This is a huge, light bluish-green gem that is super brilliant and lustrous, and nearly clean except for only a few tiny veils that our hyper-sensitive camera picks up much more readily than the human eye. A museum piece to be sure! It is an old stone, cut decades ago and long stashed away with the specimens in a prominent mineral collection. This is an IMPORTANT collector piece and , without a doubt, an investment-grade gem. It is as nearly clean as you can ask for in such large stone of a rare species, and it was recut to modern standards by Spectrum-Award winner Mark Kaufman for me. THERE IS NO COLOR IN MINERALS OR GEMS LIKE THAT OF A PHOSPHO!!! Smaller stones cut from the same old hoard recently sold out, at Tucson a few years ago, at $2500 per carat. Wholesale.

We feel there is strong upside for these gems, as the few remaining great crystals out there will tend to be preserved at the prices they currently command, making large stones like these very rare commodities. In the past, surviving crystals were readily cut as the gems were worth more, before the modern mineral specimen market. These are absolutely stunning in person! I am not normally into faceted gems, but when they get this rare and this gorgeous, and merge with mineralogical rarity, how could i say no? I am told confidently by two well known gem trade experts that this is the biggest and best phospho cut gem on the market in years and is certainly among the top cut phosphos known to exist.

This intensely grape-juice purple amathyst cluster is from the famous finds of 1991, a find which combined the famous color of the locality with both size AND lustre. Most pockets had 1 or 2 of these qualities, but not all three in the same specimen. Still to this day, this is remembered as one of the best pockets ever from the locale, and I would argue it ranks among the best pockets of amethyst, period. The piece is complete all around, showing wonderful 3-dimensionality in volume. It looks as if the two major crystals are "curled" around each other, points going different directions and making the piece more space-filling than most such clusters - where the terminations come to a single common center, with mass concentrated more around the lower-base. There is some contacting and minor damage around the bottom periphery only; and i will mention a very trivial, eye-unseen ding atop that you can spot only on close examination - but the major crystals are pristine where it matters, and you have this wonderful 3-dimensionality that i think makes this piece more dramatic than most such. The piece was purchased in 1991 by Hubert de Monmonier , after the find. It was never cleaned until I obtained in in an deal with the University of Arizona Museum, where his collection was bequeathed. Hefty , at approx 600 grams. Never cleaned, and never trimmed to stand well, and hence never shown on display in the museum.
