Latest Patents
Among his notable contributions, Cheng's latest patents include a groundbreaking "Gemstone Colour Grading Process and Grading System." This invention involves a systematic approach to assigning a color grade to diamonds. The process includes determining the N3 and C-center content of a diamond, which is then compared to a previously acquired data set from a range of diamonds. By correlating the N3 and C-center content with color grades from prior data, diamonds can be accurately graded.
Another significant patent encompasses a "Method of Marking a Diamond, Markings Formed from Such Methods and Diamonds Marked According to Such Method." This process focuses on applying a non-optically detectable authentication marking on diamonds using a focused ion beam (FIB) writing process. The alteration in the optical characteristics of the diamond's surface results in a marked portion that remains invisible to the naked eye but can be detected through imaging methods. This invention helps prevent counterfeiting and assists in recovering stolen precious articles.
