FAQs

Rings from the 1920s typically feature geometric motifs, intricate milgrain detailing, and the prominent use of platinum paired with yellow gold, reflecting the transition from Edwardian grace to early Art Deco boldness.

Jewellers of this era frequently combined durable platinum settings with 18-carat yellow gold bands, allowing white metals to enhance the brilliance of diamonds while maintaining a warm gold shank.

Authentic pieces often display hand-cut diamonds such as old European or single cuts, genuine hand-carved milgrain edges, traditional makers marks, and period-specific gold and platinum hallmarks.

A vintage ring pairs effectively with contemporary minimalist bands to create a mixed-metal stacked look, contrasting modern clean lines with historical intricacy.

Preserve the integrity of antique rings by having settings and prongs professionally inspected annually, avoiding harsh ultrasonic cleaners on delicate older stones, and storing the piece in a soft-lined box.
