Product Description for Min .30ct 4.5x4.5mm Emerald Cut Emerald
The name "emerald" comes from the Greek "smaragdos" meaning "green stone." Except the rare few, emeralds have inclusions that are generally accepted as well as treatments, which are normally stated and should not be a deterrent to purchasing. Even though they have a hardness of 7.5 to 8 on Mohs' scale, emeralds are sometimes brittle. Emeralds should only be cleaned with warm soapy water and a soft brush. Avoid ultrasonic and steam cleaners, which can cause breaks in emerald jewelry.
