Description

This antique 18ct gold and platinum trilogy ring features a vivid sapphire between two bright old-cut diamonds. The central sapphire displays an excellent, rich royal blue tone that contrasts beautifully with the crisp light of the diamonds. Together, they form a harmonious trio that captures the refined simplicity of early 20th-century jewellery design.

The slim gold band and platinum settings give the gemstones a clean, classic presentation, typical of fine antique craftsmanship. This is a wonderfully balanced piece, elegant yet full of life and colour.

FAQs

A trilogy ring, also known as a three-stone ring, traditionally represents the past, present and future of a relationship, gaining significant popularity during the Victorian and Edwardian eras.

Traditional construction typically involves 18-carat yellow or white gold and platinum settings, housing natural gemstones such as mined sapphires, rubies or emeralds flanked by diamonds.

Authentication involves examining the hallmarks for metal purity, checking for hand-cut gemstone facets such as old European or mine cuts, and looking for signs of hand-craftsmanship under magnification.

A three-stone ring serves as a versatile piece that pairs seamlessly with minimalist wedding bands or can be worn as a standalone statement piece for daily wear.

Regular cleaning with warm soapy water and a soft brush, alongside professional annual checks of the claw settings, ensures the security of the stones and preserves the metal finish.
