Description
This specimen features uvite tourmaline crystals to 2.0 cm on magnesite. The uvite crystals are sharp, lustrous and glassy. They are in excellent condition – no damage. The superb main uvite crystal has a dark purplish hue, contrasting well with the magnesite. The magnesite crystals are also very fine and in excellent condition.
The uvites on this piece have a predominantly darkish purple hue – it is not bright or vivid deep purple. The uvites from this particular find are pleochroic, and this phenomenon is visible upon careful examination of this specimen – as one views the crystals closely from different angles, subtle dark greenish hues (typical of Brumado uvites) are discernable from certain directions. The greenish hues are visible when looking through certain prism faces.
A super display piece of pleochroic uvite.
