Exodus 28:20

Exodus 39:13

39:13 and the fourth row, a chrysolite, an onyx, and a jasper. They were enclosed in gold filigree settings.

sn U. Cassuto (Exodus, 375-76) points out that these are the same precious stones mentioned in Ezek 28:13 that were to be found in Eden, the garden of God. So the priest, when making atonement, was to wear the precious gems that were there and symbolized the garden of Eden when man was free from sin.
