A striking vintage ring by Uncas, crafted in sterling silver with a deep black onyx cabochon framed by shimmering marcasite.
The elongated oval setting recalls classic Art Deco proportions, balancing bold geometry with delicate surface detail. A polished onyx center stone provides rich contrast against the soft sparkle of double rows of marcasite, creating depth and quiet drama without excess.
Substantial yet refined, the piece sits low and comfortably on the hand, with fine engraving at the reverse — a thoughtful detail that speaks to its quality construction. An elegant example of mid-century sterling design with timeless presence.
