claudetite

Claudette is a rare, pink to reddish-brown variety of quartz, named after the French mineralogist, Abbé René-Just Haüy, who was also known as Claude. It is typically found in pegmatites and hydrothermal veins, often associated with other minerals such as topaz, tourmaline, and beryl. Claudette is valued for its unique color and is sometimes used in jewelry and lapidary work. Its formation is believed to be the result of the incorporation of iron and titanium impurities during the crystallization process. The term "claudette" is also used to refer to a type of French country dance, but in the context of mineralogy, it specifically denotes this variety of quartz.
