Exodus 28:21-23

Amplified Bible

²¹ The [engraved] stones shall be twelve, according to the names of [the twelve tribes of] the sons of Israel; they shall be like the engravings of a signet, each with its name for the twelve tribes. ²² You shall make for the breastpiece chains of pure gold twisted like cords. ²³ You shall make on the breastpiece two rings of gold, and shall put the two rings on the two ends of the breastpiece.
