Used as an ornament to decorate the fingers, arms, wrists, and also the ears and the nose. Rings were used as a signet (Gen. 38:18). They were given as a token of investment with authority (Gen. 41:42; Esther 3:8-10; 8:2), and of favour and dignity (Luke 15:22). They were generally worn by rich men (James 2:2). They are mentioned by Isiah (3:21) among the adornments of Hebrew women.
Ring
A ring could carry a king’s authority. In Esther 3, the king takes the ring from his hand and gives it to Haman, and the decree is “sealed with the king’s ring.” Elsewhere rings are simply treasure. In Exodus 35, men and women bring “rings, and tablets, all jewels of gold” as willing gifts, and in Numbers 31 the men bring rings, chains and bracelets “to make an atonement for our souls.” Proverbs gives a sharp proverb of the opposite kind: “a jewel of gold in a swine’s snout” is the picture of beauty without good sense. The ring stands for what a person is trusted with or gives away.

As a jewel of gold in a swine's snout, so is a fair woman which is without discretion.
