Vintage 18ct Gold and Platinum 0.5ct Diamond Solitaire Engagement Ring

1940 - 1960
For Sale by Corvidae Antique
Description

Beautifully simple and understated but undoubtedly impressive, this tall sparkling diamond solitaire reeks of old-time glamour and would make the perfect vintage engagement ring.

The brilliant-cut gemstone (5mm, 0.50 carats) appears dazzlingly white on the finger, with a fantastic bright white fire. The open-back cathedral setting lets the light shine through and the stone has a lively sparkle with no obvious inclusions to the naked eye.

Dating from around the 1940s-50s, the ring is in excellent vintage condition.

Marked 18CT PLAT.

Size: O (UK), approx 7.25 (US). The shank is approximately 2mm wide and the top of the diamond sits around 7mm above the finger. Can be resized.

Weight: 2g.

FREE INTERNATIONAL SHIPPING!

Why Sellingantiques dated this piece to THE 1950s:
Internal stamp reading 18CT PLAT: standard British workshop marking from the mid-twentieth century.
Geometric pierced shoulders: transitional styling between late Art Deco and early post-war jewellery.
Coronet claw head: setting style favoured during the 1940s and 1950s.
Softening along the outer edges of the band: wear from regular handling over decades.

This vintage Art Deco ring dates from the 1950 period and functions as an engagement ring. The mixed-metal design combines a yellow gold band with a platinum mount holding a single round diamond in a claw setting. The shoulders display geometric openwork decoration and milgrain bead detailing flanking the central stone. The setting measures 0.5 cm high, 0.5 cm wide, and 0.5 cm deep. Suitable for modern daily wear, the ring slides onto the finger to add a touch of period glamour to any outfit. The mixed yellow gold and silver-toned metals provide a contrasting two-tone appearance, while the tall mount lifts the brilliant-cut gemstone above the band. The interior shank bears clear hallmarks marking the piece as eighteen-carat gold and platinum. The open-back gallery allows light to pass directly through the diamond from underneath.

FAQs

A diamond solitaire ring features a single central diamond set on a metal band. In vintage design, particularly from the early-to-mid 20th century, solitaire rings often feature platinum heads to securely hold the stone and emphasise its clarity, contrasted against a yellow gold band.

Platinum provides exceptional strength and a neutral white tone that enhances the optical brilliance of diamonds, whereas yellow gold offers durability and traditional warmth for the shank. Combining both metals allowed jewellers to reduce wear on intricate settings while maintaining a classic yellow gold appearance.

Authentic vintage rings typically feature hallmarks indicating metal purity, such as 18CT or PLAT, stamped inside the band. Additional markers include period-specific design details like hand-cut diamonds, geometric shoulder settings, or illusion mounts characteristic of Art Deco and mid-century metalwork.

A vintage diamond solitaire pairs easily with modern minimalist bands, slim diamond eternity rings, or mixed-metal stacking bands. The simple silhouette of a solitaire allows it to complement both historic heirlooms and contemporary pieces.

Clean the ring periodically using warm water, mild liquid soap, and a soft-bristled brush to remove accumulated oil from behind the setting. Have a professional jeweller inspect the claws periodically to ensure the diamond remains securely held.
