onyx

onyx (ŏn´Ĭks), variety of cryptocrystalline quartz, differing from agate only in that the bands of which it is composed are parallel and regular. Its appearance is most striking when the bands are of sharply contrasting colors; black and white specimens are often used for cameos. Onyx was used in Roman times for the fabrications of vases and cups. Sardonyx contains onyx and carnelian or sard. "Onyx marble," "Mexican onyx," and "Oriental alabaster" are terms applied to travertine.

Onyx

Onyx

A precious stone whose properties were believed to resemble those of jasper; it was also supposed to increase saliva in boys and cause bad dreams. If applied to the eye, it was believed to remove anything noxious.

The onyx was also believed to create strife, cause melancholy, and cure epilepsy. According to the Bible, an onyx was the eleventh stone in the breastplate of the High Priest (Exod. 28:20), but it is possible that this stone (in Hebrew, shoham ) is known today as beryl.
