1.00ctw Mixed Round Irradiated Black Diamond Parcel
Description: The name "diamond" comes from the Greek word "adamas", meaning "the unconquerable." Diamond earned this named as the hardest gemstone, ranking a 10 on the Mohs' scale--the highest rank possible. Diamond's cutting resistance is 140 times greater than ruby and sapphire, the next hardest stones on the scale. Irradiation treatment is sometimes used to enhance the color of diamonds. During this treatment, the stone is exposed to high-energy sources (like electrons) to create wonderful colors.
