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 between 1920 and 1935, is characterised by geometric shapes, rectilinear lines, bold colour contrasts, and symmetrical patterns influenced by modern industrial architecture.

Pieces from this period were predominantly crafted in platinum or white gold to showcase white diamonds and coloured gemstones such as emeralds, sapphires, and rubies, frequently finished with fine milgrain borders.

Authentic Art Deco rings feature period-accurate gemstone cuts, hand-applied milgrain work, geometric step-cut or target settings, and hallmark stampings consistent with early 20th-century metallurgy.

A geometric Art Deco statement ring serves as an accent piece that pairs with both structured tailored clothing and minimalist modern evening wear.

Emeralds should be cleaned gently using warm water, mild soap, and a soft cloth, avoiding ultrasonic cleaners, steam, and harsh chemicals that could affect gemstone oiling treatments.
