This process can dissolve certain inclusions and enhance the gem’s color, making it more visually appealing.

“No heat” sapphires, in contrast, are prized for their untouched, natural state. They have not been subjected to the artificial enhancement of heat treatment, allowing their inherent beauty to shine through without any external modification.
