The general methods of jade maintenance, such as frequent cleaning, avoiding violent collisions, and away from grease chemicals, many collectors may be well aware. However, in addition to this, jade of different qualities also need to have unique care and maintenance.

First, jade: jade in many jade, high hardness and good toughness, but the processed jade jewelry is not as "sturdy" as the original stone, in the process of engraving, its structure may be damaged and fragile, and, Jewelry is generally not thick enough and is easily damaged.

Emerald

Third, ruby, tourmaline, topaz, diamonds, etc.: Although the texture is hard, but it is also very brittle, can not withstand the impact, even if hard as diamonds, it is easy to crack under impact.

Fourth, amethyst: Amethyst is very sensitive to temperature, intense light or long time high temperature will make it fade.

Fifth, pearls, corals: pearls and corals are not high in hardness, they are easily worn and lose their luster. In addition, the two are highly demanding on the environment, such as human sweat, chemical smell, etc., which may damage their quality.

6. Malachite and turquoise: The chemical properties of the two are unstable, and they are easily affected by the corrosion of acid and alkali, and their hardness is not high.

Lapis Lazuli Bracelet

7. Lapis lazuli: Lapis lazuli is a granular composition. When cleaning lapis lazuli, it is especially important to avoid soaking and rinsing with water.
