Antique 1.89ct Diamond and Platinum Three Stone Ring Circa 1925

1900 - 1920
For Sale by AC Silver
Description

A stunning, fine and impressive antique 1.89 carat diamond and platinum three stone ring; part of our collection of diamond engagement rings.

This stunning, fine and impressive diamond platinum three stone ring has been crafted in platinum.

The pierced decorated antique ring setting is embellished with a claw set 0.85ct Old European round cut diamond.

The central stone is flanked with a 0.56ct and 0.48 Old European round cut diamond, claw set in a vertical trilogy arrangement.

The elevated ring shoulders integrate with the claw setting and blend seamlessly with the plain platinum ring shank.

This platinum trilogy ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This impressive antique engagement ring is supplied with three IDGL diamond grading report certificates.

Such evenly coloured diamonds in a low swallow tip claw setting are becoming increasingly difficult to locate.

This 1920s 3 stone diamond ring in platinum is a timeless and meaningful piece. Its trilogy design, symbolising the past, present and future, makes it an exceptional choice for engagements or milestone anniversaries, as well as a refined addition to a personal jewellery collection.

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 3 stone engagement ring is excellent quality, set with impressive evenly colour matched diamonds displaying a fine white colour, brilliance and presence; although one of the diamonds is clarity graded at P1, it shows no unsightly black inclusions.

The diamond ring is an excellent gauge of platinum and is in excellent condition.

The ring has a fine and delicate shank, which is often the case with original antique rings.

Reflections in photographs may detract from the true representation of this stunning three stone engagement ring.

Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

Art Deco three-stone rings, also known as trilogy rings, feature three gemstones set side-by-side along the band, symbolizing the past, present, and future. Designed during the 1920s and 1930s, these pieces typically combine platinum mounts with precise geometric symmetry and prominent claw settings.

During the 1920s, platinum became the preferred metal for high-end jewellery due to its strength and ability to hold intricate stone settings with minimal visible metal. Diamonds were commonly cut in old European or transitional styles and set in multi-claw collets.

Authentic 1920s diamond rings often display platinum hallmarks, hand-cut old European or transitional diamond cuts with larger facets, open culets, and specialized crown settings or subtle millgrain details along the collet.

An antique trilogy ring pairs well alongside a contemporary slim platinum or white gold band. The clean profile of a 1920s setting allows it to be worn either as a central engagement piece or stacked with plain geometric bands.

Clean platinum diamond rings using warm water, mild liquid soap, and a soft-bristled brush to remove accumulation under the settings. Annual professional inspection is recommended to ensure all claws remain secure around the diamonds.
