This bangle is approx. 2.5 inside inside dimension, 3 in outside, approx. 3/4 inch deep. Hand carved from a single piece of Ruby zoisite.
Ruby-zoisite is the natural combination of both ruby and zoisite crystals in a single specimen. Ruby-zoisite was discovered in northeast Tanzania by Tom Blevins, an English prospector. To this day, Tanzania remains the only source for ruby-zoisite. He thought that he had found vast ruby deposits but it turned out to be a green zoisite matrix with large inclusions of mostly opaque ruby. Ruby-zoisite is also heavily included with black hornblende minerals.
