Appearance Dark, blackish gray, nontransparent an, with a metallic luster, hematite is faceted, cut into cabcchons, or engraved; it lends itself well to the marl of signet rings. Other pieces are fashioned into necklac• beads or pendants.


Distinctive features The metallic luster and color ar• highly characteristic; still more so is the red streak it leaveif drawn across a piece of unglazed porcelain. Occurrence Now used comparatively rarely, the typ from Great Britain, Switzerland, Germany, and the island c' Elba is suitable for ornamental purposes.


Value Very low. Skillfully engraved items are worth more.
