onyx - Easton's 1897 Bible Dictionary :

  Onyx
  a hail; claw; hoof, (Heb. shoham), a precious stone adorning the
  breast-plate of the high priest and the shoulders of the ephod
  (Ex. 28:9-12, 20; 35:27; Job 28:16; Ezek. 28:13). It was found
  in the land of Havilah (Gen. 2:12). The LXX. translates the
  Hebrew word by smaragdos, an emerald. Some think that the
  sardonyx is meant. But the onyx differs from the sardonyx in
  this, that while the latter has two layers (black and white) the
  former has three (black, white, and red).
