0.56ct Diamond and 18ct White Gold Solitaire Style Ring - Antique Circa 1920

1900 - 1920
For Sale by AC Silver
Description

A stunning, fine and impressive antique 0.56 carat diamond, 18 carat white gold and platinum set solitaire style ring; part of our diverse range of diamond engagement rings.

This stunning, fine and impressive antique 1920s solitaire ring has been crafted in 18ct white gold with a platinum setting.

The pierced decorated square shaped setting displays a feature pavé set 0.40ct Old European cut diamond, encompassed with four eight cut diamonds.

The principal stetting is flanked with stepped shoulders, each incorporating three eight cut diamonds, pavé set in a tiered Art Deco formation.

The pierced decorated ring shoulders blend seamlessly with the plain, hallmarked ring shank.

This 1920s diamond ring is hallmarked to the interior of the shank with the 18ct gold mark (18CT) and the platinum mark (PT); this ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18 carat gold and platinum.

This impressive ring is supplied with an IDGL diamond grading report certificate for the feature stone, in addition to an IDGL diamond grading report card for the supporting stones.

This Old European cut Art Deco solitaire ring is best suited to occasions such as engagements, milestone anniversaries, vow renewals or meaningful personal celebrations. Its authentic Art Deco provenance and timeless design also give it outstanding heirloom appeal, making it a unique alternative to a modern engagement ring.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.

Condition

This solitaire ring is excellent quality, set with impressive diamonds displaying a fine white colour and brilliance.

The ring is an excellent gauge of gold and is in excellent condition, with clear hallmarks to the interior of the shank.

Reflections in photographs may detract from the true representation of this fine example of antique fine diamond jewellery.

Art Deco diamond rings from the 1920s are characterised by clean geometric lines, symmetry, and architectural influence. Settings from this era frequently feature stepped shoulders, platinum detailing, and central diamonds framed by linear accent stones.

During the 1920s, jewellers commonly used platinum and 18ct white gold to achieve a monochromatic look that complemented diamonds. Stones were typically hand-cut, such as old European or cushion cuts, set into claw or illusion mountings.

Authentic 1920s rings often feature period hallmarks or metal stamps, such as platinum or 18ct marks, inside the band. Hand-carved geometric details, openwork galleries, and old-cut diamonds with distinct facets also indicate period authenticity.

An antique solitaire ring pairs effectively with minimalist modern bands or delicate white gold stacking rings. The geometric architecture creates a refined contrast when worn next to clean, contemporary pieces.

Clean the ring using warm water, mild soap, and a soft-bristled brush to remove dust from behind the setting. Avoid exposure to harsh household chemicals, and schedule regular professional checks to ensure the claws remain secure.
