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.

An Edwardian diamond trilogy ring features three gemstones traditionally symbolising the past, present, and future of a relationship. Created during the early 20th century, these designs frequently incorporated fluid twist mounts and delicate platinum detailing.

Edwardian rings were typically constructed using an 18ct yellow gold band topped with platinum setting claws to emphasise the whiteness of the diamonds. Hand-cut diamonds, such as old European cuts, were standard for fine jewellery of this era.

Authentic Edwardian pieces feature fine milgrain graining along the metal edges, platinum-faced mountings over gold shanks, and hand-cut diamonds with distinct faceting. Historical hallmark stamps inside the band provide further evidence of date and origin.

An antique trilogy twist ring can be worn as a standalone statement piece or stacked alongside slim modern platinum bands. The fluid diagonally-set mount complements contemporary linear jewellery designs.

Clean the ring gently using warm water, mild soap, and a soft-bristled brush to clear residue from beneath the claw settings. Store the piece individually in a fabric-lined box to avoid contact with other jewellery.
