But over the years he learnt how to inspect diamonds and now he grades their quality, using specialist equipment. "The natural diamonds and lab-grown diamonds are so similar that once, even after a lab test there was a confusion about the origin of a diamond. The diamond had to be tested twice to make sure that it was a lab-grown," he says.
The second process is called Chemical Vapour Deposition and involves putting the seed in a sealed chamber filled with carbon-rich gas and heating to around 800C. The gas sticks to the seed, building up a diamond atom by atom. These days, a one carat diamond - a popular size and common in engagement rings - made in a lab would be around 20% cheaper than its naturally-formed equivalent.Snehal Dungarni is the chief executive of Bhanderi Lab Grown Diamonds, which he started in 2013. It uses the CVD process to make diamonds."Comparatively they are cost and time-effective and save mining and extraction costs - making them human and environmentally kind," he says.
