Some people know that the physical and chemical properties of jadeite are stable, and exposure to the sun is far from reaching the melting point of jadeite, which will have no effect on jadeite. Some people think that exposure to the sun for a long time will make jadeite varieties worse and the color will fade. So which statement makes more sense?

First of all, we know that jade is a kind of jade. Looking up information on the Internet, we can know that the melting point of jade is between 1692- 1773 degrees Celsius. Although the composition of different jadeites is very different, we can be sure that high-temperature exposure is far from reaching the melting point of jadeite, which means that exposure in the sun will not change the appearance of jadeite.

Then the next question, will exposure make the variety of jadeite worse? First of all, we know that jadeite is formed at low temperature and high pressure. The tighter the molecular structure inside jadeite, the better the water head of jadeite. Exposed to strong sunlight for a long time, the intermolecular heel of jadeite will increase, making the head of jadeite worse, which is often called "dehydration".

Now, let's go to the last question. Will high temperature exposure make jadeite lighter? Take green as an example. First of all, we know that the coloring factor of green in jadeite is chromium ion. The closer the molecular structure between jadeites is, the better the water head of jadeites is, the higher the light transmittance is, and the brighter the color is from the appearance. If you are exposed to the sun for a long time, the color of jadeite will fade from the outside because of the increase of molecular spacing, although it will not lead to the decrease of chromium ions in jadeite.

Therefore, we come to the conclusion that exposure will not destroy the appearance of jadeite, but will make jadeite thicker and lighter in color. Therefore, Jade is still afraid of the sun exposure. Especially jewelry and bracelets, you must pay attention to sun protection.
