Weak emissions at 596 and 597 nm, which are specific to CVD diamond and also unstable at high temperature, were recorded overlapping with side bands of the NV 0. Clear emissions from SiV – at 736.6 and 736.9 nm were detected. Photoluminescence spectroscopy collected at liquid nitrogen temperature with 514 nm laser excitation (figure 2, left) showed emissions from NV centers with zero-phonon lines (ZPL) at 575.0 nm and 637.0 nm with moderate intensities. Except for absorptions from the diamond itself, no other defect-related absorption was detected in this region. Absorption spectroscopy in the infrared region revealed this was a typical type IIa diamond. In addition, a few tiny pinpoints were present. The strong graining distributed throughout it created a “wavy” appearance (view the video clip below). (figure 1 GIA report number 2225246686) weighed 16.41 ct and measured 13.97 × 13.87 × 9.56 mm, with G color and VVS 2 clarity. This princess-cut diamond produced by Shanghai Zhengshi Technology Co.
In this note, GIA’s New York laboratory reports on a new record for CVD laboratory-grown diamond. Records for crystal size and quality are frequently broken. In addition to many other applications, laboratory-grown diamonds have become an expanding segment of the jewelry industry. Growth technology of single-crystal diamond has advanced significantly in the last two decades, for both the high-pressure, high-temperature (HPHT) and chemical vapor deposition (CVD) methods. This is an as-grown diamond no post-growth treatment was applied for color improvement, either before or after faceting. The new record size for CVD laboratory-grown diamond-16.41 ct, with G color and VVS 2 clarity-has been achieved by Shanghai Zhengshi Technology Co.
