Exodus 28:17-21

And you shall mount on it four rows of stones; the first row shall be a row of ruby, topaz, and emerald;

and the second row a turquoise, a sapphire, and a diamond;

and the third row a jacinth, an agate, and an amethyst;

and the fourth row a beryl, and an onyx, and a jasper; they shall be set in gold filigree.

The stones shall be engraved according to the names of the sons of Israel: twelve, according to their names; they shall be like the engravings of a signet, each according to his name for the twelve tribes.
