What defines a geometric sapphire ring?

These rings are defined by their reliance on straight lines, symmetry, and architectural motifs, most commonly associated with Art Deco design. Stones are cut and set to form deliberate patterns such as squares, panels, and target shapes. Sapphires in these pieces are frequently paired with diamonds in platinum or gold settings, creating a strong visual contrast between the deep blue stones and the bright metalwork.

How can I tell a 1920s ring from a 1960s revival?

Original 1920s and 1930s pieces often exhibit specific fabrication details like hand-cut calibre stones, delicate millegrain edges, and platinum construction designed to hold stones securely in thin mounts. Revival pieces from the 1960s may use different casting techniques or alloys, though they replicate the earlier styles. Examining the wear, hallmarks, and stone cutting styles helps clarify the date of manufacture.

How do I care for an antique sapphire ring?

Antique sapphire rings require gentle handling due to their delicate settings, particularly pieces featuring fine platinum millegrain or intricate openwork galleries. Regular professional checks ensure the small claws holding calibre or baguette stones remain secure. Cleaning should be done with warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners that can dislodge stones in older mountings.
