A variety of garnet that is transparent and commonly deep crimson with tinges of purple. Its colour may resemble that of ruby. It is cut in several forms; when cut en cabochon (usually as hollow cabochon to lighten the colour), it is called carbuncle. Some stones are shaped in India by tumbling, and sometimes now are faceted.
The main sources are Sri Lanka (formerly Ceylon), Fort Wrangel in Alaska, and India. An alternative name is ‘almandite’. A sub-variety has inclusions of needles) of foreign substances, which sometimes form a weak 4-pointed or 6-pointed star such stones are called ‘star almandine’.
