A Brief History of the Sapphire

Sapphires were prized as early as 800 BC in ancient Persia, where people believed the sky’s color was a reflection of sapphire stones. The gemstone later became a favorite among royalty and the Church, often set into crowns and ecclesiastical rings.

The British royal family continues this tradition—Princess Diana’s (now Kate Middleton’s) iconic engagement ring features a 12-carat Ceylon sapphire.
