Yellow diamond blank preparation method based on irradiation technology

Abstract

The invention belongs to the technical field of material science and gemstone processing, and particularly relates to a yellow diamond blank preparation method based on an irradiation technology, which comprises the following steps: selecting a colorless diamond blank synthesized by high temperature and high pressure (HPHT) without obvious impurities except a seed crystal surface, putting the colorless diamond blank into high-energy electron beam equipment, and irradiating according to a certain dose, and then taking out the irradiated diamond blank, and enabling the diamond blank to be yellow through a heat treatment technology. The method is easy and convenient to operate, has high flexibility and controllability, is expected to provide a new way for manually preparing the high-quality yellow diamond blank, and improves the product quality and the economic value.
