The Excelsior which means "higher" is not only one of the worlds largest diamonds it is the second largest diamond ever found. It originally weighed 995.2 carats. The diamond was cut into ten pieces, the three largest weighing 158, 147 and 130 carats. These pieces were then cut into 21 gems ranging from 70 carats to less than 1 carat. An African mine worker found the diamond as he was loading his truck, he kept the find secret until he could safely turn it over to the mine manager who rewarded him with some money, a horse and a saddle. www.valuablestones.com
