Rarer than almost anything else, this species is probably the most sought after mineral species to collectors (and among the most expensive). Crystals like this were found almost 70 years ago, and not in this quality since. This phospho displays fish-tail twinning, high luster, transparency, and an exquisite pastel green color. Admittedly, the crystal has been contacted on the back side, but this does not, in any way, affect the beauty and rarity of this specimen. As well, it is the most desirable fishtail twin habit and has a substantial amount of cutting rough material within! You need to see these in person to understand what a uniquely surreal, glowing color this presents!
