Gemological Institute of America (GIA) scientists discovered a “never-before-seen” cloud feature in a lab-grown diamond that was submitted for testing. The feature resembled text from an old manuscript.
As stated by the writers in Gems & Gemology, the scholarly publication of the Gemological Institute of America, “The dichotomy of a thoroughly modern diamond with a cloud feature that evoked an ancient text provided an interesting submission,” published in spring 2024.
Sally Eaton-Magaña, senior manager of diamond identification at GIA in Carlsbad; Manisha Bhoir, manager of analytics at GIA in Mumbai; and Girish Dodiya, associate diamond grader at GIA in Surat, noted that they had never observed the “lines” of clouds previously.
The 1.67-carat, pear-shaped, D-color, SI1 chemical vapor deposition (CVD) diamond was sent for analysis to the GIA‘s Surat lab.
