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 from the 1920s through the 1930s, is defined by geometric shapes, bold gemstone combinations, symmetrical layouts, and intricate metalwork such as millegrain borders.

Fine jewellery from the 1930s frequently utilised platinum or white gold settings, accented with diamonds and high-grade coloured gemstones including sapphires, emeralds, and rubies.

Authentic pieces usually feature hand-applied millegrain detailing, period-appropriate gem cuts such as cabochons or single-cut diamonds, and vintage precious metal hallmarks along the inner shank.

An Art Deco sapphire ring serves as a statement dress piece that pairs effectively with minimalist contemporary tailoring or formal evening attire.

Clean gently using warm water, mild soap, and a soft-bristled brush. Store separately in a fabric-lined box to prevent harder gemstones from scratching adjacent metals or stones.
