Vintage French 18k Yellow Gold Rose Cut Diamond Domed Band Ring

18k yellow gold rose cut diamond wide band ring, circa 1980s, designed with a polished domed profile and a ribbed gadroon style pattern that frames the center stone. The ring features a raised bezel set rose cut diamond with an irregular hand cut outline, giving the piece an antique inspired character while maintaining a substantial, sculptural form. The wide yellow gold band has a smooth rounded interior and a softly raised exterior, with carved vertical grooves that create dimension across the front of the ring. A worn French eagle head hallmark is visible, indicating 18k gold, consistent with French assay marking. This ring weighs 9.2 grams, measures 3/8 inch wide, and is a ring size 9. The piece shows light surface wear and minor marks consistent with age and prior use. Its combination of French 18k gold, a raised rose cut diamond, and a bold wide band silhouette gives the ring a distinctive balance of vintage design and everyday wearability.
