Pictured above is Janak and below is younger brother Uptal (computers). Below is the youngest brother, Kamal (optics), who is working on Sergey's latest OctoNus® product. Helium Rough is the newest scanner that can identify the size and location of inclusions in rough diamonds and plan for cutting around them to produce higher clarity diamonds. The machine was being tested and has the cover off. I have deliberately blurred the image unfortunately because this technology is top secret.

The shot on the right shows a diamond model (brown) on the scanning table. When the polished diamond model(s) have been planned the black circular light thing between the diamond and the screen is a high power laser that burns a small line all around the stone so the sawyer knows where to cut the stone (most diamonds are sawn and 2 polished diamonds are produced from the 2 halves).
