The fifth, sardonyx,.... Which is partly of the sardian, and partly of the onyx stone, which resembles a man's nail, from whence it has its name; it is reddish, bordering on white; it may be thought to answer to the onyx in the breastplate, on which was written the name of Joseph.
The sixth, sardius; the same with the sardine stone, Re 4:3 of a blood colour, and what is commonly called a cornelian: it is found in Sardinia, from whence it has its name, and in Bohemia and Silesia, though those of Babylon are the best.
This was Reuben's stone.The seventh, chrysolite; a stone of a dusky green colour, with a cast of yellow; by its name it should have the colour of gold. Schroder says it is found in Bohemia, and that it is the same the moderns call the topaz.
Some think it answers to "tarshish" in the breastplate, rendered "beryl", on which was the name of Asher.The eighth, beryl; a stone of a pale green colour, thought to be the diamond of the ancients: it may answer to the "ligure" in the breastplate, which the Targum on So 5:14 calls "birla", and had the name of Dan on it.
