thebrainscoop:“Life cycle of Axis,” carved green beryl, aka beryllium aluminum cyclosilicate, aka emerald. Obtained by Marshall Field on his expedition to Madagascar in 1912, although it is unclear if the carving was added at a later time. I like to imagine the world when Field returned with this specimen, the massive undertaking of a worldly expedition, the delight and wonder of an unexpected natural treasure in hand. -- source link
