These dazzling gems have not mined like this from the earth, but created in a Russian facility.
This research facility in Novosibirsk, Russia is run by Tairus, a synthetic gemstone manufacturer.
The facility develops synthetic emeralds like these, and the idea is to achieve an appearance that is as close to natural emeralds as possible.
......
No other manufacturer in the world has managed to achieve such transparency claim the developers.
......
This method currently used is based on what was first developed in the Soviet Union by the scientists of the Institute of Geology and Geophysics in the 1970s and early 1980s
......
It became a real revolution in its field.
It was so quickly spread that developing artificial emeralds was no longer a problem, the only problem was growing high-quality ones.
......
"It turned out a unique method because the emeralds grew in an autoclave made of heat-resistant steel, there was no need to make any lining of noble metals, it included very little iron, which spoils the colour very much, therefore, I believe that this was one of the outstanding developments in the field crystal growth in the Soviet Union," says scientist-geologist and geochemist Vladislav Shatskiy.
In 1989, on the basis of the Institute, the Tairus enterprise was created, which continued to improve the technologies, and at the moment is the world leader in the research and production of hydro thermally grown emerald crystals.
It takes about one month to develop a stone weighing from 600 to 1,000 grams.
......
According to the company, the quality achieved can mislead even professional gemmologists.
In the early stages, the company even received expert opinions that their stones were natural emeralds from an unknown deposit.
"Some inexperienced gemmologists simply issue a certificate that this is a natural material, they cannot find differences, but we are not proud of this, we say that we have come so close to nature that all the differences have already been erased, although, of course, we sell everything only as (synthetically) grown stones, but their characteristics are very close to nature," says General Director of the Tairus company, Oleg Kholdeev.
