'Rosettes' in the Bible

With the work of a jeweler, like the engravings of a signet, you shall engrave the two stones according to the names of the sons of Israel. You shall have them set in filigree [settings] of gold.

You shall make filigree [settings] of gold,

The other two ends of the two cords you shall fasten in the two filigree settings in front, putting them on the shoulder pieces of the ephod.
