Description

French blue

1) Commercial name used for synthetic ultramarine blue originating from the early 19th century when the pigment was first imported from France (Mayer 1969).

2) The rough cut stone from which the Hope diamond was cut. The 'French Blue' or 'Tavernier Blue' stone was mined from the Kollur mine in Golconda, India. It was purchased by Jean-Baptiste Tavernier in 1660 who then sold it to King Louis XIV of France. It was stolen in 1792 during the French Revolution. The Hope Diamond, cut from the French blue stone, appeared on the market in 1812. The sotne now resides in the Smithsonian Institution's National Museum of Natural History.
