The ring head is crafted from 18-karat rose gold (750/1000) , delicately flanked by rectangular motifs in white gold , while the yellow gold band brings a beautiful harmony to the whole. This subtle contrast between the three golds lends this antique ring a unique charm, at once warm, luminous, and refined. At its center, the ring is set with a rectangular-cut blue topaz of approximately 3.02 carats . Its soft, luminous light blue beautifully captures the light. The stone is set in a millegrain bezel setting , a refined jewelry detail that emphasizes its antique appearance and highlights the precision of the craftsmanship. Note: the topaz has a slight chip on one of the edges of the table facet, discreet to the naked eye and consistent with the history of this antique jewel. This gold and topaz Tank ring is a very pretty antique-style ring with incomparable charm. It will be perfect for a woman who appreciates distinctive jewelry, creations steeped in history, and exceptional vintage pieces .
