Brazil is famous for producing fine quality cat's eye tourmaline, but Africa and the USA (Maine and California) are also well-known for high quality crystals. Most of the tourmaline available today is mined from either Mozambique, Nigeria, Sri Lanka (Ceylon), Madagascar or Tanzania. Cat's eye tourmaline typically occurs in either green or pink and can exhibit strong pleochroism. Depending on the angle from which it is viewed, a single stone can exhibit different colors, or depths of color. Larger stones tend to exhibit deeper and richer colors. Cat's eye tourmaline is typically cut en cabochon to maximize the desirable chatoyancy. The orientation of cut is very important for cat's eye gemstones. Most cat's eye tourmaline is typically cut into oval or pear shapes, because these shapes tend to mimic the shape of the rough, which maximizes the preservation of carat weight.
