Although diamonds are the hardest things that people know, they are also damaged or dimmed. Your diamond jewelry will benefit from the following points. 1. Don't mix your diamond jewelry or confuse it with other jewelry, otherwise the diamond will scratch or scratch each other; 2. Place your diamond in a gem box made of fabric or a box with a separate layer; 3. Don't wear diamond ornaments when you are doing rough work. Even if the diamond is tough, it will be broken due to too heavy impact; 4. Regularly use a commercial jewelry cleaner - an ammonia mixture, or a mild detergent, immerse the diamond in the solution during operation, and use a soft brush to remove dust and dirt from the bottom of the diamond. 5. Do not place your gemstones in chlorine-containing bleach or other chemicals as they can cause etch pits or fading of the inlaid metal; 6. Check your jewelry at least once a month, send your diamonds to a professional, and check for loose or worn gems. stock hookah,warehouse hookah,stock shisha CHINA HOOKAH SMOKING LIMITED , http://www.chinahookah.com
