Crafted in platinum and hallmarked with the French dog’s head stamp, this antique eternity ring features 25 bright transitional cut diamonds, totalling approximately 1.75 carats. Each sparkling diamond is grain-set, encircling the 3.25mm wide band in a seamless loop of brilliance. The sides are delicately engraved, a detail that highlights the craftsmanship of this Paris-made piece.
Likely dating to the 1920s, the ring combines transitional cut diamonds, commonly used between 1920 and 1940, with a Paris platinum assay mark introduced in 1912. In very good vintage condition, with only a few minor surface nibbles to some stones, consistent with its age and wear.
A refined example of early 20th-century French jewellery design - elegant worn solo, as a substantial wedding band, or stacked with other favourites.
