Amber is an extremely rare and precious organic gemstone with extraordinary spirituality and life. Amber is also a naturally occurring resin fossil. It is light in weight and low in hardness. It can exhibit a variety of different colors and states, but generally exhibits a yellow or brownish yellow and transparent resin luster. The color or opaque state, such as blood, beeswax, one is a charming red color, and the other is opaque and warm.
Amber is often made into jewellery, in various shapes and styles, but all are very beautiful. However, amber itself has characteristics that make all amber ornaments very fragile. They may be damaged if they are worn slightly, so the maintenance of amber It is particularly important, so what about the maintenance of amber?
1. Amber is rich in organic matter, and the general chemical substances have corrosion and erosion effects, so those commonly used cosmetics have become the focus of attention, and can not let such things touch the amber.
2. Amber is very fragile, it does not fall or touch, and it is easy to leave scratches on its surface. Therefore, do not wear it during strenuous exercise, and do not put it together with other hard jewelry.
3. Amber can not withstand the high temperature and direct sunlight, otherwise it is easy to melt and deform, usually pay attention to temperature changes and avoid direct sunlight.
4. Amber is easy to get dusty, and the cleaning work should be done properly. Just wipe the amber surface with a damp cloth. Wearing amber for a long time can give amber a brighter luster.
