Diamonds are a girl’s best friend, and emeralds are more than appropriate, such as the Bahia Emerald discovered in Brazil. At 840 lbs. (380 kg), this massive raw gemstone is estimated to be worth $370 million.
The emerald itself is embedded within stone, with protruding spikes that are noted as being the size of a human arm. Though there has been growing dispute regarding the ownership of the Bahia Emerald, one thing is for sure -- this emerald is certainly one-of-a-kind, and I would love to get my hands on it as well.
