Pretty Art Deco Platinum Diamond three stone Ring 0.45ct total. This superb quality ring has a very bright old cut diamond of 4mm x 4mm diamond of 0.25ct to the centre, either side of which are two further bright old cut diamonds of 0.10ct each. Total diamond weight is 0.45ct and diamonds set in a very pretty and protective collette setting. Really pretty and classical three stone ring in a lovely setting, diamonds have a really bright sparkle and are excellent quality. There are no hallmarks on the shank but almost certainly dates to the early 20th century and has been tested as platinum. This ring would make a wonderful engagement ring with plenty of wow factor and a timeless feel of antique cuts. The stones are all set in a strong and protective platinum setting. The ring is in excellent condition for its age, with some minor thinning to the shank. There are no chips, nibbles or cracks to the stone. Size UK Q and U.S Size 8 the total weight is 2.9g.

FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric precision, sleek lines, and a strong architectural influence, moving away from the flowing curves of the preceding Edwardian and Art Nouveau periods.

Platinum became the dominant metal of the Art Deco era due to its strength and ability to hold delicate settings securely with minimal metal visibility, frequently paired with diamonds and calibrated precious gemstones.

Authentic pieces typically feature period-specific gemstone cuts such as old European or single cuts, hand-crafted platinum construction, and often bear period hallmarks or makers marks consistent with 1920s and 1930s manufacturing techniques.

An antique ring pairs effectively with modern minimalist clothing to create a striking contrast, or it can be stacked alongside contemporary bands for a curated, mixed-era aesthetic.

Platinum and diamonds should be cleaned periodically using warm soapy water and a soft brush, and stored individually in fabric-lined boxes to prevent scratching against other pieces.
