What is Bedimming in Gemology?

Bedimmed is a term used in gemology to describe a diamond that has been treated to improve its color. The treatment involves irradiating the diamond with high-energy particles, such as electrons or X-rays, to create a more vivid color. The process can be used to enhance the color of diamonds that are naturally light in color, or to mask inclusions or imperfections in the stone.

The term "bedimmed" is derived from the word "beam," which refers to the high-energy particles used in the treatment process. It is often used interchangeably with the term "color-treated diamond." While bedimming can improve the appearance of a diamond, it is important to note that the treatment can be expensive and may not be permanent. Additionally, some consumers may be hesitant to purchase a bedimmed diamond because they may view it as less valuable or authentic than a natural diamond.
