As soon as I heard the gems heating up, I felt as if I was as arrogant as the beauty of the beauty. Isn't this a deception? Smecta? In fact, the gem heating is another mystery, don't worry, let's make it clear.
Heating only for more eye-catching
Gemstones are also "to face". Because most of the people who love gems are "members of the Appearance Association", the gemstones with bright colors and pure and transparent inside are more popular among buyers. In order to meet the needs of the market, scientists use various methods to improve their appearance, making the gem look more beautiful and purer. Heating is one of the most common ways.
Heating only changes the appearance
At a certain temperature, after several hours of heating, the gemstone often has two improvement results - the color of the gem changes, and the effect of the inner inclusion on the appearance of the gemstone is changed.
There are two effects of heating on the color of the gemstone.
It can make the color of the gem become richer, such as the ruby ​​becomes more delicate after heating; it can also change the color of the gem, such as the amethyst turns yellow after heating.
Heating can also dissolve the unpleasant inclusions in the gemstone, such as the milky white translucent "stone" heated to become a bright and transparent sapphire; or the very pleasing inclusions, such as heating with a small number of needles The sapphire of the inclusions causes the inclusions to precipitate and exhibits a very beautiful starlight effect.
Which gems are heated more
Crystal is more common in the list of heated stones, amethyst can be transformed into citrine, green crystal after heating; smoky crystal can also get citrine or yellow-brown crystal.
Heating is optimized for non-treatment
Gemstone treatment refers to the beauty of the gemstone by pickling, injection molding, etc., changing the elemental composition inside the gemstone and adding other substances.
Heating did not add other elements to the interior of the gem, just physically changing the appearance of the gem.
According to Chinese national standards, heating (ie heat treatment) is a kind of gemstone optimization method, and it is not clearly marked on the ordinary national inspection certificate.
