GIA scientists examined the gemstone which is a D color .53 carat round brilliant cut diamond with a unique cloud inclusion that looks like the profile of a faceted round brilliant diamond. It seriously looks like someone typed a gemstone emoji inside the gem.
In their blog post, GIA said the diamond-shaped cloud appeared to be completely natural when it was examined in the microscope. GIA stated, "In this diamond, the cloud’s presence adds beauty, value, and distinction. Thanks to an observant and skillful polisher, we get to see another “brilliant” example of an intriguing cloud inclusion in diamond."
Scientists used photomicrography to determine the depth of the cloud and found that not only was it three-dimensional, but part of the center reached the diamond's surface.
They also compiled photoluminescence maps from thousands of spectra--each with pixels that are 10 microns in size. This shows the peak intensity of the gemstone and showed that the diamond cloud had a lower intensity than the surrounding diamond yet a portion of the girdle section in the cloud had a higher H3 intensity.
I'll include the link to the blog post in the podcast description for you to check out.
