What exactly does clarity mean as it relates to a diamond?
Few diamonds are perfect. Given their enormously violent birthing process in volcanoes millions of years ago, most diamonds have tiny remnants of their beginning or intruder minerals inside them. Thankfully, most of these inclusions, as they’re called, are hidden from sight. It takes magnification to see them. A clarity grade is an evaluation of the degree to which a diamond is free of blemishes and inclusions. Inclusions can be thought of as natural birthmarks on a diamond. Since no two diamonds have exactly the same inclusions, this property can also be described as an identifying characteristic.
