As an accepted industry standard, sapphires are heat-treated to improve color, clarity, and overall appearance. Some sapphires are found closer to thermal venting in the earth, which produces exceptional color through natural heating. By heating sapphires that are not found in these locations, we mimic this natural process. No radiation, chemicals or health risks are involved in this process. As is common with almost all sapphires available today, the majority of Brilliant Earth sapphires are heat-treated. Brilliant Earth also carries un-heated sapphires at a premium.Avoid
