This is sterling and marked 'S' on back (see photos).
Beautiful vintage Southwestern / Native American–style bolo tie clasp featuring a large oval green malachite cabochon set in hand-stamped sterling silver.
The clasp showcases classic Navajo design elements including a scalloped outer edge, triangular and line stamp work, and a substantial bezel-set stone with vivid natural green banding. The back features a traditional bolo slide clasp designed to grip a leather cord securely.
This piece is unsigned, which is common for authentic mid-century Native American jewelry made for trading posts and regional sale. A striking statement clasp that works well as a replacement slide or as the centerpiece of a custom bolo tie.
