Description

A small minature piece with beautiful cacoxenite and beraunite needles, hundreds of tiny white clusters of matulaite, and clusters of very rare pink leucophosphite crystals. Due to the very low amounts of sodium in this pegmatite leucophosphite is one of the rarest phosphates found here, only known from perhaps 6 specimens! There are also some pale pink strengite balls in one corner of the vug. Beautiful and rich piece!
