Diamonds 'transformations' are extremely toxic

Russian scientists have found a way to "color" a range of colors for ordinary diamond jewelry.

Their work like magic tricks. From the familiar transparent diamonds in reality right before the eyes turn into colors. Without any paint here. Only pure knowledge and modern technology.

The most important factor is the stone itself. The color change is only suitable for low-nitrogen rocks - the main compound in diamonds. To determine the composition, diamonds are tested in infrared spectrophotometers. After such a test , the stone was sent to the laboratory.

There, under the pressure of diamond structure changes, add the mixture. That is, people try to reproduce the same process of diamond discoloration in nature. Only if the diamond itself changed color, the process took millions of years, in the laboratory - only 3 days and nights.

In order to change the color of the diamond, it is heated to a temperature of 1500 degrees Celsius. And necessarily in the vacuum compartment - Mikhail Sorokin, senior researcher of Moscow Steel and Alloy Institute (MISA), clicked. strong.

Diamonds can now "color"

'Diamond is considered an unstable thermodynamic object. If you don't use a vacuum compartment to burn it, the stone will simply burn in such a high temperature. '

A diamond can be 'painted' with different colors. For example, to make it green - it should be extracted from the stone of carbon atoms. If you want a shiny yellow diamond - add a nitrogen mixture. The diamond will turn blue, if using hydrogen atoms. Each such stone costs thousands of dollars. However, it is still much cheaper if compared to the colored diamonds that nature has made, - said NikolaiPolushin, head of the MISA superhard alloy lab.

Several years ago, blue crystal diamonds weighing just over 1 carat were sold at a Southeast Asian exchange for $ 10 million.

The color change does not affect the durability and quality of the diamond. Even an experienced jeweler without special equipment does not distinguish whether a sparkling stone is a work of nature or human. You can 'paint' the diamond to make the precious stone the color of the national flag. Because scientists are saying that sooner or later people will learn to make every diamond bring its own soul.
