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.
