Trapiche Ruby

Trapiche ruby is a rare variety of ruby that is currently found in only 2 locations on earth: Myanmar (Burma) and India.

Trapiche rubies are named after a six-spoked cogwheel used in sugar cane mills (trapiche de cańa azucar in Spanish).  They often have sharp, hexagonal growth lines that create a fixed, 6-ray star and are often cut into slices to show off their unique appearance.
