Description

This specimen consists of rose-colored magnesite and green hydrotalcite. Giobertite is an old synonym for magnesite. The "Ophimagneiste" mentioned on the label means a ophicarbonate where magnesite is the predominant carbonate.

Comes with old Félix Pisani (1831-1920) label. Félix Pisani, French chemist, mineral dealer and author, was born 28 April 1831 in Constantinople. The dates are uncertain, but he first began to sell mineral specimens to the British Museum in 1869. His laboratory became a favorite meeting place of local mineralogists until the establishment of the Mineralogical Society of France in 1878, of which Pisani was one of the founders. His own papers in chemical mineralogy date from 1854 to 1915.
