Circa 1920 Diamond Ring
A circa 1920 diamond ring brings the geometry and fine metalwork of the Art Deco era directly to the hand.
Circa 1920 Diamond Ring
A circa 1920 diamond ring represents the height of the Art Deco style, combining geometric layouts with brilliant or old cut stones. These pieces typically take the form of solitaire engagement rings, multi-stone trilogy settings, or intricate cluster arrangements.
The versions most commonly met on this page pair central diamonds with precious surroundings of platinum or 18ct white gold. Alongside pure diamond compositions, many examples incorporate coloured gemstones such as sapphires, emeralds, rubies, and pearls.
Originating predominantly from this specific period of the early twentieth century, the rings reflect a shift towards lighter, stronger metal mountings that allowed maximum light to enter the stones. Buyers encounter both French workshop creations and domestic British or European pieces.
How they were made
Makers utilised platinum alongside 18ct white gold and yellow gold to construct lightweight yet secure settings that could support significant diamond carat weights. Platinum became the preferred metal for intricate piercing and millegrain detailing because of its strength and bright white finish.
Stones were shaped predominantly as old cuts, old European cuts, or brilliant cuts, then hand-set into bezels, claws, or cluster patterns alongside calibré cut accents. Master jewellers balanced the brilliance of the central diamond with precise geometric arrangements of smaller side stones.

Listings here feature diamonds paired with platinum, 18ct white gold, and yellow gold within distinct Art Deco engagement and dress ring forms.
What varies in quality
The standard of a piece depends heavily on the precision of the metalwork, particularly the delicacy of the pierced galleries and the crispness of any millegrain beaded borders. Superior examples maintain structural integrity without sacrificing the airy, light appearance characteristic of the period.
Stone selection and cutting style dictate the upper tiers of the collection, where symmetrical old cuts or unheated coloured gems display superior light return and depth of colour. Balance between the central diamond and any supporting sapphire, ruby, or emerald determines overall harmony.
The Circa 1920 Diamond Ring Glossary
- Old cut
- A diamond cutting style typical of earlier periods, featuring a smaller table, higher crown, and deep pavilion that produces a softer, candlelit sparkle compared to modern round brilliants.
- Millegrain
- A decorative technique consisting of a row of tiny raised metal beads along the edge of a setting, adding texture and a finished appearance to platinum or white gold mounts.
- Calibré cut
- Gemstones specifically shaped and cut to fit tightly into a geometric channel or pattern within a ring, often used for borders of sapphires or onyx.
- Trilogy ring
- A ring set with three stones, traditionally symbolising the past, present, and future, frequently featuring a larger central diamond flanked by two smaller ones.
- Solitaire
- A single gemstone mounted on its own in a ring, allowing the focus to rest entirely on the central diamond and its surrounding metalwork.
Circa 1920 Diamond Ring: Frequently Asked Questions
How do I care for a platinum setting?
Platinum is exceptionally durable and withstands daily wear well, requiring only occasional cleaning with warm soapy water and a soft brush to restore its natural lustre.
Avoid exposing the ring to harsh household chemicals or abrasive surfaces that might dull the surrounding metal or loosen delicate stone settings over time.
Are these rings suitable for daily wear?
Most pieces from this period were built for everyday use, particularly those mounted in sturdy platinum or high-carat gold frameworks.
Prudence suggests removing the ring during heavy manual labour or contact sports to protect older stone cuts and intricate claw settings from accidental impacts.
What defines the Art Deco style?
Art Deco design relies on clean geometric lines, symmetry, and stylised motifs that broke away from the flowing, organic curves of the preceding Edwardian and Art Nouveau periods.
This aesthetic appears in the sharp angles of cluster arrangements, stepped shoulders, and the precise arrangement of calibrated accent stones.
How can I tell an old cut from a modern cut?
Old cut diamonds typically feature smaller tables, higher crowns, and larger culets at the base, creating a distinct visual depth under ambient light.
Modern brilliant cuts are engineered using strict mathematical proportions designed purely to maximise optical return, producing a different pattern of facets and brilliance.
