A rare mineral composed of lead and tellurium that forms crystals, named after the Cesare mine in Italy.
From Italian Cesare (a proper name) plus the mineral suffix -lite meaning 'stone.' The mineral was named after the location where it was first discovered or studied.
Rare minerals like cesarolite are the geologist's version of hidden treasure—they're so scarce that finding a good specimen can be worth serious money to collectors and researchers!
