FranckeiteThis fantastic specimen was mined in the late 1970s early 1980s and stands out as one of the best pieces of this material that I have offered from this prolific discovery. I think it goes without saying that the finest specimens of Franckeite are found at this mine. This is one of my favorite species from Bolivia, as it has an interesting chemistry, unique crystals, and it belongs to the only group of minerals that form naturally round or cylindrical

steel grey crystals of this rare lead

lustrous Brookite crystals with squared-off terminations sitting beautifully on Quartz matrix

sharpness and translucency sitting on bright and wonderfully contrasting

black cyclic twinned crystals which are associated with Quartz on matrix

as most Brookites are found lying flat on matrix

A wonderfully well-crystallized

The piece is virtually undamaged on the display side and when propped up

rich blue-green colored prismatic Amazonite crystals with unusually etched / altered reddish-brown sections on the terminations

this is one of the sharpest and most euhedral crystals I've ever had to offer from Myanmar

In all the years of mining

Along with the translucency and the fact that it’s on matrix
