Vintage Navajo Sterling Silver Coral Ring

This ring is new old stock from the 1970's/1980's so it is unworn and unused.  It is Native American handmade and it is unmarked and tests as sterling.  It measures a ring size 5 3/4 and the face of the ring measures 7/8 inch long.  It weighs 5.3 grams and it is in great vintage condition.
