FAQs

Art Deco sapphire cluster rings typically feature a prominent central sapphire encircled by a halo of diamonds, showcasing geometric balance, precision metalwork, and strong visual contrast characteristic of early 20th-century jewellery design.

Rings from this era were frequently crafted using yellow gold or platinum mounts, featuring natural sapphiresoften sourced from Sri Lanka (Ceylon)and accented with old European or brilliant-cut diamonds.

Ceylon sapphires are recognised by their medium-to-vibrant blue hue and natural crystal inclusions, while authentic mid-century settings feature hand-finished claw work, period hallmarks, and characteristic wear on the underside of the setting.

A substantial gemstone cluster ring acts as a standalone statement piece that complements streamlined modern tailoring or minimalist formalwear, allowing the colour contrast of the gemstones to take center stage.

Clean the ring using warm water, a small amount of mild dish soap, and a soft brush, taking care around claw settings. Store the piece individually in a lined box to avoid contact with other jewellery.
