The mount is finished in delicate filigree work throughout. Total weight is 3.86 grams, ring size 5.25.\u003cbr\u003e\u003cbr\u003eThe old European cut, a precursor to the modern round brilliant, features a high crown, small table, and softly rounded outline, faceted by hand to maximize brilliance under candlelight rather than the electric lighting of today, giving it a distinctive warmth and soft sparkle prized by antique jewelry collectors. Black onyx has been prized since antiquity for its deep, opaque black color, and here the diamond set directly into its center creates a striking point of contrast and brilliance against the dark, polished surface. The surrounding filigree work, an openwork metalworking technique using fine twisted wire, adds delicate, lace-like detail characteristic of earlier jewelry eras.\u003cbr\u003e\u003cbr\u003eElevate your jewelry collection with this old European cut diamond and onyx ring, a striking and historically rich addition for collectors of vintage jewelry. Its dramatic dark stone, sparkling center diamond, and intricate filigree make it a captivating conversation piece as well as a thoughtful gift for an admirer of antique design.\u003cbr\u003e\u003cbr\u003eSome of the photographs featured on this website have been enhanced or processed using artificial intelligence (AI) tools.
