How do I care for an antique sapphire ring?

Sapphires possess high hardness, yet the delicate platinum or gold settings require gentle handling during everyday wear. Avoid ultrasonic cleaners and harsh chemicals, opting instead for warm soapy water and a soft brush. Store antique rings individually in padded boxes to prevent metal friction and stone abrasion. Regular professional inspection ensures the claws securing the central blue stone and accent diamonds remain tight.

Can these rings be resized easily?

Resizing depends primarily on the band material and the extent of the shoulder design. Plain shanks in 18ct gold or platinum present straightforward adjustments for a skilled bench jeweller. Complex geometric patterns extending down the band restrict major size alterations without disrupting the pattern. Consult a specialist familiar with antique settings to preserve the structural integrity of the piece.

What defines an art deco blue ring?

Symmetry, linear motifs, and high-contrast colour combinations distinguish these designs from earlier Victorian or Edwardian styles. The integration of calibre cut stones creates flat planes of intense blue alongside sparkling diamond borders. Platinum construction permits ultra-fine settings that give the geometric shapes a lightweight yet durable architecture. This combination of structural boldness and crisp colour remains the hallmark of the aesthetic.
