Why It’s Special

The vast majority of sapphires on the market are heat-treated to improve their color and clarity — a practice that has been standard in the trade for centuries. An unheated sapphire, however, shows its beauty exactly as it formed in the earth, with no human intervention. Fewer than 1% of gem-quality sapphires remain untreated, making them exceptionally scarce. Collectors prize them not only for their natural color, but also for the authenticity and purity they represent.
