Why Sellingantiques dated this piece to THE 1940s:
Notched transverse collars on the tapering shoulders: late Art Deco geometric design.
Large culet visible through the diamond table: transitional European cutting technique.
Platinum coronet claw setting joined to a gold shank: classic mid-century two-tone construction.
Subtle softening along the shank edges: natural handling over decades.

This Independent Date Guide was compiled by Sellingantiques using its own proprietary system. It works only from the photographs shown on this page and is never told the date the dealer has declared. It is a guide, not a guarantee of age, and occasional errors can occur.

This 1940s Retro engagement ring is made from 18k yellow gold and platinum with a diamond. The design includes a solitaire setting with a round central stone held in a six-claw platinum head, complemented by stepped shoulders on a slim tapering shank. The yellow gold has a polished metallic finish with contrasting white metal around the setting. Visible details include a sparkling faceted cut stone, double notch detailing on the shoulders, and a clean metallic band with smooth curves. Today, a ring of this style is worn daily on the hand as a traditional engagement symbol, suitable for pairing with a wedding band or wearing alone. It works well for formal occasions or everyday wear, complementing both vintage and modern attire.

FAQs

Engagement rings from the 1940s often feature transitional or old European cut diamonds set in mixed metals, combining yellow gold bands with white gold or platinum claw settings. The design era bridges late Art Deco geometric elements with classical, streamlined solitaire styling.

During the 1940s, jewellers typically crafted engagement rings using 18ct yellow gold for the shank paired with platinum or white gold setting heads to enhance the white appearance of the diamond.

Authentic pieces from this period feature hand-cut facet patterns typical of old European or transitional cuts, alongside period hallmark stamps inside the band and hand-finished claw collets.

A classic mid-century diamond solitaire can be effortlessly paired with modern minimalist gold bands or stacked alongside textured vintage wedding rings for a multi-tonal aesthetic.

To preserve a vintage diamond ring, clean it gently using warm water, mild soap, and a soft-bristled brush, while scheduling regular professional inspections to check claw integrity.
