Maintenance is no different from ordinary gemstones The maintenance method of crystal is the same as that of general gemstones. First of all, be careful not to place it with other accessories to avoid collision and scratches. When using hot springs, housework, makeup, and swimming, the crystal should be removed to avoid chemical attack. Sexual permanent injury; because its surface is as bright as a mirror, it is tarnished from sweat and oil stains. It is recommended to wipe it with a soft cloth after each wear; color crystals should avoid long-term exposure to sunlight.

Holding the crystal in your hand for a while, the natural crystal feels cool, while the glass jewelry is generally warm, and the temperature that is rapidly changing in the hands may be non-natural crystal. 2. Price. In terms of price, the price of natural crystal is more expensive than synthetic crystal. It is said that good goods are not cheap, so when faced with crystals whose price is lower than the market price, it is necessary to leave one more heart. 3. Hardness. Natural crystals have a hardness of 7 and glass has only 5, as long as the hardness is greater than 5, the glass can be drawn. Therefore, you can use a crystal to perform a simple test on the glass to see if there are scratches. 4. Color. In terms of color, just pay attention to the green crystal. There are very few green natural crystals, so most of the green crystals on the market may be synthetic. 5. Impurities. Crystals with inner inclusions are generally not fake, because forgery of such things is costly, not only costly, but also the effect is easy to see through.
