Antique 1910s Edwardian Platinum Engagement Ring featuring a Natural Rose Cut Diamond

This authentic Edwardian-era platinum engagement ring, dating to the 1910s, showcases the delicate craftsmanship and refined elegance of early 20th-century jewelry design. Hand-fabricated in solid platinum and stamped “CT PLAT” inside the shank, this ring reflects an early platinum hallmark commonly used during the Edwardian period.

The ring features a natural rose cut diamond set at the center, chosen to complement the original character and proportions of the antique mounting. Rose cut diamonds are prized for their soft glow and romantic, understated sparkle — a striking contrast to modern brilliant cuts and a perfect match for this era’s lace-like metalwork.

The mounting displays classic Edwardian details, including fine bead-set accent diamonds, delicate milgrain edges, and an airy pierced gallery — all hallmarks of hand craftsmanship from a time before mass production. Elegant, lightweight, and timeless, this ring offers a rare opportunity to own a true antique platinum piece with enduring charm.
