Large quantities of strain were not limited to discrete lamellae, unlike in-group dos expensive diamonds. Checking Electron Microscopy (SEM) and you will Cathodoluminescence (CL) Imaging. Cathodoluminescence and secondary electron images (SEI) were collected at the NMNH using a Thermo Fisher Quattro checking electron microscope provided with a retractable genuine color RGB CL sensor (red, green, and you may bluish avenues). All of the analyses was accumulated having fun with reduced cleaner mode at the room temperature with 15 kV and you can step 1.3 nA at the a working distance from ten mm.

Earlier pink diamond research has and noticed the newest cellular dislocation networks inside the reduced-nitrogen form of IaA diamonds, enveloping grain that have yellowish environmentally friendly luminescence of H3 locations (Gaillou et al., 2010, 2012).
