Agate

a beautifully-veined semi-transparent precious stone, a variety of quartz. Its colors are delicately arranged in stripes or bands or blended in clouds. It is mentioned four times in the text of the Authorized Version, viz., in (Exodus 28:19; 39:12; Isaiah 54:12; Ezekiel 27:16) In the two former passages; where it is represented by the Hebrew word shebo it is spoken of as forming the second stone in the third row of the high priest's breastplate; in each of the two latter places the original word is cadced, by which, no doubt, is intended a different stone. [RUBY] Our English agate derives its name from the Achates, on the banks of which it was first found.
