Probably in such issues as national economic growth or standard of living India is far from being in top, but when it concerns diamonds precisely diamond mining, cutting, polishing and anything else associated with diamonds India has no worthy competitor in this field. Indeed, it is believed that first diamond was found in the ‘Country of Gods and Monkeys’ and a great number of all world-known diamonds come from there, too: Koh-i-Nor diamond, Regent (Pitt) diamond, The Orlov, the Hope diamond are just to name a few.
Being so to say the ‘diamond-oriented’ country, India is however not the first to learn about synthetic diamonds, which are now serious competitors to mined stones. But now it’s time for India to get to know more about real diamonds which are not yet mined.
Diamonds can be grown from a hydrocarbon gas mixture using the chemical vapour deposition (CVD) method, which can pave way for an exciting future for gemmologists in India.
A presentation on how CVD synthetic diamonds could be produced in large quantities in India was given by gemmologist Jayshree Panjikar at a seminar during the second annual convocation of Panjikar Gem Research and Tech Institute (PANGEMTECH), held recently on the institute’s Pune campus.
“In the recent months, synthetic CVD diamonds have been encountered in gem testing laboratories worldwide. It will not be long before synthetically grown CVD diamonds become rampant in India. The time has come for us to know what are synthetic CVD diamonds,” said Panjikar.
The methane gas is a regular by-product of biogas plants, said Panjikar, “Which through a few hours of processing , can be converted into chemical vapour deposition (CVD) synthetic diamond. These diamonds are now used for a wide range of high technology industrial applications and for jewellery, “ informed Panjikar.
About the CVD grown synthetic diamond scenario in India, Panjikar said, “We have to accept the fact that CVD grown synthetic diamonds are going to increase and instead of seeing this as a threat, one should see it as an opportunity. There are many biogas plants that produce methane gas as a by-product, which can be utilised using proper technology to create synthetic diamonds.” She further said that these diamonds have great potential in developing as a cottage industry in the country and in turn increase employment opportunities.
At the second annual convocation of PANGEMTECH, students received their certificates for completing course in basic gemmology, advance gemmology, diamond grading and professional gemmologist. The chief guest on the occasion, Herr Guenter Lorenz, proprietor, So!lutions (Germany), gave away the certificates. He advised students to take advantage of the rich Indian culture and use the variety of colours and designs available in the country, which is rarely seen elsewhere in the world.
The convocation began with a seminar organised by PANGEMTECH alumni association on crystal healing by Meghana Thite, an expert on crystal therapy. She demonstrated on the healing powers of crystals like red garnet, aquamarine, citrine, carnelian, aventurine, lapis lazuli, rose-quartz, amethyst and clear rock crystal.
