FAQs

An unheated Ceylon sapphire originates from Sri Lanka and has not undergone any thermal enhancement to improve its colour or clarity, making it a scarcer and more desirable gemstone.

Antique rings frequently utilise platinum, yellow gold, or white gold, often featuring hand-carved settings, millegrain detailing, and hand-cut diamonds alongside the central gemstone.

Authentication involves examining the metal hallmarks, assessing the cut and polish of the gemstones for period-specific tool marks, and obtaining certification from a reputable gemmological laboratory.

An antique ring can be worn as a standalone statement piece or paired with minimalist wedding bands to highlight the historic design without visual competition.

Antique jewellery should be cleaned gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners, and stored separately in a lined box to prevent scratching.
