Diamond enhancements are certain peculiar treatments performed on natural or synthetic diamonds, usually those already cut and polished into a gem, which are designed to better the gemological characteristics of the stone in one or more ways.
These techniques generally include laser drilling to remove inclusions, application of sealants to fill cracks, treatments to improve a white diamond's color grade, and treatments to give fancy color to a white diamond.
In addition, coatings are increasingly used to give a diamond simulant such as cubic zirconia a more "diamond-like" appearance. One such substance is carbon-an amorphous carbonaceous material, which looks like a diamond that has some physical properties similar to those of the diamond. Advertising suggests that such kind of coating would transfer some of these diamond-like properties to the coated stone, hence enhancing the diamond simulant. Techniques such as Raman spectroscopy should easily identify such type of treatment.
