Exodus 39:11-14

in the second there was a turquoise, a sapphire, and an emerald; in the third there was a jacinth, an agate, and an amethyst; in the fourth there was a chrysolite, an onyx, and a jasper. Gold was put around these jewels to attach them to the chest covering, and the names of the sons of Israel were carved on these twelve jewels as a person carves a seal. Each jewel had the name of one of the twelve tribes of Israel.
