ultramarine
Sign in to saveAlso known as ultramarine blue, dark ultramarine blue
Ultramarine is a deep blue pigment which was originally made by grinding lapis lazuli into a powder. Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from. Between the 14th and 15th centuries, it was as expensive as gold in Europe.

Ultramarine is a deep blue pigment which was originally made by grinding lapis lazuli into a powder. Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from. Between the 14th and 15th centuries, it was as expensive as gold in Europe.
The name ultramarine comes from the Latin word . The word means 'beyond the sea', as the pigment was imported by Italian traders during the 14th and 15th centuries from mines in Afghanistan. Much of the expansion of ultramarine can be attributed to Venice which historically was the port of entry for lapis lazuli in Europe.
