Characteristics of gemstones
1, "beauty", gorgeous, glittering and translucent, dazzling.
If a gem is not beautiful, it can't be called a gem. This kind of beauty is either colorful, transparent and clean, or has special optical effects (such as cat's eye, color change, night light, etc.), or has special patterns (such as chrysanthemum stone, agate, plum blossom jade, etc.).
2, "long", hard and wear-resistant, can persist for a long time.
Because of its high value, people must expect it to be durable, valuable and even heritable. One of the reasons why diamond is the most expensive gem is that it is the hardest in the world and is not afraid of corrosion. Therefore, most of the high-value gems in the world are silicate minerals with high hardness and corrosion resistance (such as jadeite), a few oxides (such as rubies and sapphires) and elemental minerals (such as diamonds), while the soft and corrosive gems (such as xiuyan jade and Southern Jade) are of higher value. But there are also a few precious stones that are not included, such as opals and pearls.
3, "rare", less output
Rare things are precious. Emerald, which is extremely rare in the world, is worth tens of thousands of dollars per carat (0.2 g) because of its superior quality, while some beautiful and "enduring" gems (such as amethyst) have always been low in price because of their large output and easy mining. Some ordinary rocks, after pondering, also have the characteristics of beauty and durability, but they cannot become a member of the gem family. The reason is that things that are easy to get will be cheap.
Because precious stones are expensive, you should also pay attention to maintenance at ordinary times.
Maintenance method
1, don't wear jewelry when exercising or doing heavy work, so as to avoid irreparable damage caused by collision. Even in daily wear, we should pay attention to avoid wear and sudden blows, otherwise it will damage even the most difficult gemstones to wear.
2. When storing jewelry, store jewelry in a box or soft cloth to avoid contact with other jewelry. Most precious stones are harder than gold, silver and platinum. If they are not placed separately, they may scratch the surface of other jewelry.
3, wearing jewelry, should pay attention to check once a month, if there is any loose mosaic phenomenon, should be repaired in time.
4. Wearing jewelry after modification and makeup can prevent hair gel or cosmetics from damaging jewelry, thus maintaining its color.
Jewelry will lose its luster when it is stained with oil and sweat secreted by human body. So if you wear it often, clean it once a month.
6, professional care: normal wearing and pulling will eventually soften the metal parts such as claws of jewelry. So it's best to go to the jewelry store once every six months and ask a professional to check it. When necessary, professionals can repair claws, ring handles and buckles of necklaces, and reshape deformed rings. Professionals can also professionally clean your jewelry when handling it. If the gem is damaged in daily wear, it can also be polished according to your requirements.
