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

Art Deco trilogy rings feature three central gemstones representing past, present, and future, crafted with geometric precision, platinum settings, and gem-cutting techniques prominent during the 1920s.

Jewellers during the Art Deco era primarily utilised platinum or white gold for strength and colour neutrality, setting natural sapphires alongside hand-cut diamonds such as old European or old cut diamonds.

Authentic pieces from this era often display hand-carved galleries, platinum metal hallmarks, claw settings, and hand-cut facets on diamonds rather than modern machine precision cuts.

An antique trilogy ring functions as an engagement ring or statement dress ring, pairing with plain metal bands or modern tailored attire for a understated aesthetic.

Clean the ring using warm water, mild soap, and a soft brush, avoiding harsh chemicals or ultrasonic cleaners to protect the claws and gemstone settings.
