Vintage Sterling Silver Graduated Stamped Navajo Pearl Necklace

Heavy and impressive Native American handmade sterling silver necklace is unmarked and tests as sterling silver, and features graduated saucer beads ranging from 1/2 inch to 1 full inch.  The necklace measures 25 1/2 inches in length and it weighs 125.7 grams.  It is in great vintage condition.  I did not polish this necklace.
