Mined from the remote mountains of Afghanistan and Chile, this celestial blue gemstone created the most coveted pigment in Renaissance art.

This early pigment proved exceptionally stable at extreme temperatures, making it invaluable for creating lasting blues in pottery and stained glass. Zaffre’s discovery marked a crucial step in humanity’s quest to capture the sky’s perfect blue.
