Nose-jewels

Only mentioned in Isa. 3:21, although refered to in Gen. 24:47,
Prov. 11:22, Hos. 2:13. They were among the most valued of
ancient female ornaments. They "were made of ivory or metal, and
occasionally jewelled. They were more than an inch in diameter,
and hung upon the mouth. Eliezer gave one to Rebekah which was
of gold and weighed half a shekel...At the present day the women
in the country and in the desert wear these ornaments in one of
the sides of the nostrils, which droop like the ears in
consequence."
