Per GM Persida: A rare opaque gem found in shades of red from bright crimson to a rich wine hue, erythraean displays brilliant chatoyancy (aka: 'cat's eye') effects, with shimmering fibrous inclusions that have been likened to the sheen off a spool of silk. Luminous streaks of reflected light occur across the center of the gem, always perpendicular to the direction of the fibers. The best finished specimens show a single sharply defined band of light that moves across the stone when it is rotated. Cut almost exclusively into cabochons, as this cut best enhances this gem's reflective qualities. Erythraean is found mainly in the mineral-rich mines of the Turmar noble family of Zoluren."
