The Sustainable Choice

FAQs

Art Deco engagement rings from the 1930s typically feature geometric design accents, structured shoulders, and hand-cut diamonds such as Old European or transitional cuts, reflecting the architectural movement of the era.

During the 1930s, jewellers predominantly used platinum or white gold to construct settings, allowing for intricate shoulder work, geometric piercing, and secure claw settings.

Authentic period rings display hand-cut diamonds with smaller table facets, steep crowns, and open culets, paired with period hallmark stamps and hand-finished metal settings rather than modern uniform castings.

A vintage diamond solitaire can be styled alongside plain platinum bands or delicate micro-pave rings, combining historical geometric detail with contemporary minimalist design.

Clean the ring gently using warm water, mild soap, and a soft brush, and schedule periodic professional inspections to verify claw tension and overall setting security.
