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 jewellery, prominent during the 1920s and 1930s, is characterised by geometric shapes, symmetrical patterns, clean architectural lines, and the extensive use of platinum alongside diamonds and contrasting gemstones.

Art Deco rings were predominantly crafted using platinum or white gold for strength and a bright white finish, featuring hand-cut diamonds such as old European or transitional cuts, often detailed with fine milgrain borders.

Authentic pieces display period-specific features including old European or old mine cut diamonds with hand-faceted proportions, geometric shoulder detailing, hand-drawn milgrain edges, and vintage metal fineness hallmarks.

Art Deco rings integrate easily with contemporary wardrobes, complementing either minimalist modern metal bands or vintage-inspired pave eternity rings for a layered mixed-era aesthetic.

Clean gently using warm water, mild liquid soap, and a soft-bristled brush to remove dust from behind the setting, and schedule periodic professional inspections to ensure claws and settings remain secure.
