The Sustainable Choice

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.

FAQs

A trilogy ring features three gemstones set horizontally in a row, traditionally symbolising the past, present, and future of a relationship. Popularised during the Victorian and Edwardian eras, these designs frequently feature diamonds set in precious metals.

Antique trilogy rings commonly combine 18ct yellow gold shanks with platinum or silver settings to emphasize the brilliance of the diamonds. The gemstones themselves are typically hand-cut, such as old European or mine cuts.

Authentic pieces often feature official hallmarks stamped inside the band indicating metal purity and assay locations. Hand-cut diamonds display unique facets, open culets, and slight subtle asymmetries alongside decorative details like milgrain edging.

An antique trilogy ring can be worn individually as a focal piece or paired with understated contemporary gold bands. Mixing modern minimalist jewellery with detailed antique metalwork creates an eclectic look.

Clean the ring using warm water, mild soap, and a soft-bristled brush to remove debris behind the settings. Avoid aggressive chemical cleaners or ultrasonic baths to preserve older claw settings and detailed milgrain work.
