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 engagement rings from the 1920s are characterised by geometric designs, streamlined platinum settings, and the widespread use of old European cut diamonds. The era introduced rub-over bezel settings, millegrain borders, and intricate shoulder details.

During the 1920s, platinum became the premier metal choice for fine jewellery due to its strength, allowing for delicate filigree work without compromising durability. White gold was also introduced during this decade as a more accessible alternative to platinum.

Authentic old cut diamonds feature a smaller table, higher crown, open culet, and slightly asymmetrical facets created by hand cutting. Settings from the period often display hand-engraved details, millegrain edge work, and period hallmarks.

An antique engagement ring pairs effectively with a plain platinum or slender pave wedding band to keep the focus on the central stone. Stacking with minimalist contemporary bands creates a balanced contrast between historical craftsmanship and modern design.

Clean the ring using warm water, mild detergent, and a soft-bristled brush to remove built-up oils around the setting. Professional annual checks are recommended to ensure the bezel and accent prongs remain secure.
