How do I know a sapphire is unheated?

Gemmological certificates issued by independent laboratories provide definitive analysis of internal inclusions and crystal structures, confirming whether a stone has remained unheated. These reports document microscopic evidence that reveals the natural thermal history of the corundum.

Which periods are common for these rings?

Surviving examples originate predominantly from the Victorian, Edwardian, Art Deco and Mid-Century eras, spanning from the late nineteenth century to the nineteen-sixties. Each period imparts distinct stylistic hallmarks to the setting and the surrounding diamond work.

What is a star sapphire?

A star sapphire displays an optical phenomenon known as asterism, where light reflects across needle-like inclusions to form a six-rayed star shape. These stones are typically cut as cabochons to best exhibit the moving luminous pattern across the surface.

Can I wear an antique sapphire ring daily?

Corundum is an extremely hard mineral, rating nine on the Mohs scale, making these pieces durable for regular wear when properly maintained. Prongs and settings in older platinum or gold jewellery should be inspected periodically to ensure the stones remain secure.
