Special Inclusions
34.20 carats
Size: Thumbnail
2.5x1.8x1.0 cm
Location: Diamantina
Minas Gerais
Description: A colorless oval Quartz with nice clarity and a blade of an unknown mineral that has grey transparent portions and a black color zone in the middle.
My only guess to what the mineral is would be Brookite, but usually Brookite is not grey.
Under a polariscope, the color shifts to orange. Very unusual and special. It weighs 34.20 carats and comes from Brazil.
