Ligure. (Hebrew, leshem). A precious stone mentioned in Exodus 28:19; Exodus 39:12 as the first in the third row of the high priest's breastplate. It is impossible to say, with any certainty, what stone is denoted by the Hebrew term; but perhaps tourmaline, or more definitely the red variety known as rubellite, has better claims than any other mineral. Rubellite is a hard stone, and used as a gem, and is sometimes sold for red sapphire.
