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 rings from the 1920s are recognised for geometric shapes, clean lines, and symmetrical patterns. They frequently feature old cut diamonds mounted in yellow gold or platinum, reflecting a design shift towards structured, modern forms.

Rings of this period were predominantly crafted from yellow gold, platinum, or palladium, holding hand-cut gemstones like old European or cushion cuts. These diamonds feature deeper proportions, larger facets, and open culets engineered to maximize shimmer under soft light.

Authentic period rings display hand-finished metalwork, historical hallmarks inside the shank, and hand-cut facets that differ slightly from precise modern laser cuts. Microscopic inspection often reveals subtle wear patterns consistent with genuine age.

A classic antique diamond solitaire can be stacked with a modern plain gold wedding band or paired with minimalist contemporary bangles. The clean geometric profile complements both refined traditional and current everyday wardrobes.

Clean the ring gently using warm soapy water and a soft brush to clear buildup behind the stone setting. Avoid contact with abrasive cleaning chemicals and schedule regular professional checkups to ensure claw settings remain secure.
