Carbuncle. One of the gems in the high priest's breast-plate, Exodus 28:17; Exodus 39:10; it is also mentioned in Ezekiel 28:13. It must, from the derivation of the Hebrew word, have been a bright flashing gem. Some have supposed it the emerald. Carbuncle occurs again as the rendering of another term in Isaiah 54:12. The original words here may mean "sparkling stones;" perhaps the Oriental garnet is intended.
