There at least three tiny crystals of this rare beryllium phosphate on red Roscherite. Impossible to get, this came off of "larger" specimen which was previously sold.

There are three small pieces each maybe 1mm and less and each piece has great abundance of tiny white rice-shaped crystals of extremely rare Parafransoletite. This was really a one-time find from the 1980's when the Tip Top was mined for beryllium and the the rare beryllium phosphates were found. The red is Montgomeryite. You can buy these and sell two.

This is indeed one of the richest Parafransoletites around. The thing is overdosed in little white bladed, elongated Parafransoletite crystals with blunt terminations. The terminations are inclined on one side and some are kind of hackly. Many of the crystals are colorless at the center becoming white at the terminations. Most of the crystals are singles, but there are good examples of groups of two or three maybe four or five in divergent habits. The crystals measure about 0.3-0.4mm. The bright red groups are Montgomeryite, but most of the dark red to purplish red is Roscherite.
Don't pass this one up.
