Vintage Navajo Sterling Silver Black Onyx Ring — Signed NDI

A bold and beautifully constructed vintage Navajo sterling silver ring, centered with a deep black onyx cabochon and framed by flowing hand-cut leaf and feather motifs. This piece has real presence — sculptural, balanced, and unmistakably Southwestern.

The ring is stamped STERLING and bears the maker’s mark NDI, an established Navajo silversmith’s hallmark seen on quality Native American jewelry from the late 20th century. The heavy silver shank splits gracefully at the shoulders, giving the ring both strength and visual movement, while the raised setting allows the stone to command attention without overwhelming the hand.

Weighing a solid 0.5 ounces, this is not a lightweight piece. It was made to last — and to be worn.

As with all Jack Gringo offerings, this ring is sold exactly as found. We do not over-polish or remove natural age and patina, honoring the history and hands that shaped it. Once it’s yours, you’re free to polish, restore, or leave it just as time intended.
