Summary

Description
English: Albite, Beryl, Schorl
Locality: Urucum mine (Tim mine; Córrego do Urucum pegmatite), Galiléia, Doce valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org)
Size: large cabinet, 17 x 11 x 6.5 cm
Morganite with Albite on Schorl
This pegmatite has produced arguably the best and largest number of fine morganites in the world from any one small find, back about 30 years ago now. This is a HUGE specimen with so much color and impact, because of the size, that it seems fake at first! It masses/weighs just over a kilo. The crystal measures 10 x 8.5 cm , is 3.5 cm or 1.75 inches thick, and is complete all around. It has a minor indentation on the left side, that is crystallized in faces with attached albite blades over them. There are a few small spots of roughness in the front face that were filled with gap-fill epoxy (its there, but in context of size and overall impact minimal). The white spot at the base of the crystal is part of the matrix that grows up into the crystal or vice versa, and is albite as well, though massive and not crystallized. This specimen is translucent to transparent throughout, highly lustrous, and a rich pink-lavender color that is distinctly Urucum's own hue. Classically, you want these to be associated with schorl but not drowned out by the schorl - too many are actually so included they look gray or ugly. This one has just enough schorl on it to accent without taking away from the pink gemminess and transparency, the black on pink making for a better piece. More importantly, this crystal stands miraculously UPRIGHT on a matrix of solid intergrown schorl and albite! Ok, its not a miracle, but rather an excellent trim job by one of our friends. Because of its wonderful display aesthetics, this one whopper of a morganite, both literally and figuratively, for ANY locale. IT IS MUCH BETTER IN PERSON! Comes with custom lucite base for easy display.
