A billion years ago, when the diamond formed, other minerals, crystals and gases were trapped inside the diamond. After the diamond is cut and polished, any minerals and crystals remaining inside the diamond are referred to as "inclusions". The Clarity of a diamond refers to the size and positioning of these natural inclusions.
All David Keefe diamonds are natural, we do not offer treated diamonds such as diamonds which have been clarity enhanced or changed by hire pressure treatment. Our customers can purchase with assurance, knowing that all of our diamonds have been created by mother nature, without any human influence other than cutting and polishing.
