From time to time, the human body excretes sweat and grease on the skin surface, and the hand is the most accessible part of the body, so the grease on the skin often pollutes the surface of the hand. When you touch a gem with your hand, the grease on your hand can easily stay on the gem, which affects the luster and brightness of the gem. In particular, diamonds are lipophilic gems, and their surfaces are easily contaminated with grease, which greatly affects their luster.
Diamonds also need holidays.
Diamond jewelry also needs a holiday! It is best to take off the diamond ring when washing your hands, because the soap in the soap is also easy to get stuck in the gap of the ring, which greatly affects the luster and brightness of the gem. Other diamond jewelry must also be taken off when bathing, doing housework and swimming, because diamonds are easy to collide or even fall off in these cases. After all, there are only 8 claws when diamonds are set!
Don't be impatient when wearing diamonds.
There are many kinds of diamonds. The safest inlays for clothes that don't hook are inlays, but the inlays cover the whole waistline, so that light can't enter. And because the K-gold part is used more, the visual effect is not as beautiful and charming as the pointed inlay. Therefore, pointed inlay is still the most popular in the jewelry market, but pay attention to the order of wearing. Generally speaking, the order of wearing diamonds and jewelry is to wear clothes before wearing jewelry. Imagine wearing a single diamond ring finger on your hand and prong setting stockings. Is it a very dangerous thing for clothes, stockings and gems?

Diamonds pay attention to detail.
The selection of diamonds is based on "4C" to judge the price and value of diamonds. The so-called "4C" is the abbreviation of four English words beginning with C, which refers to the carat weight, clarity, color and cut of diamonds. As long as you simply appreciate the four points of "4C", you can easily understand the value and quality of a diamond. Diamond price = weight+color+clarity+cut.
Carat weight
The weight of diamonds is measured in carats (also called cards). 1 carat = 200mg = 0.2g A carat is divided into one hundred parts, and each part is called one point. 0.75 carat is also called 75 minutes, and 0.0 1 carat is 1 minute. Other things being similar, the value of a new diamond increases geometrically with the increase of diamond weight. Diamonds with the same weight will have different values due to different colors, cleanliness and cutting.
Clarity (clarity)
Diamonds are crystallized from mantle magma deep in the earth, with complex environment, diverse components and extremely high temperature and pressure. After hundreds of millions of years of geological changes, it is inevitable that there are all kinds of sundries or defects in it. The color, quantity, size and location distribution of these inclusions have different degrees of influence on the clarity of diamonds.
The clarity of a diamond is usually classified by using a magnifying glass with a magnification of 10 to classify the internal and surface defects of the diamond and their influence on the luster. According to the standard, it is divided into LC, VVS 1, VVS2, VS 1, VS2, SI 1, SI2, P 1 and P2. Diamonds are divided into five grades: excellent, very good, good and relatively good. P-class drill is also called I-class drill.
Color (color)
Diamonds have many natural colors, from precious colorless (white after cutting), rare light blue and pink to common light yellow. The more transparent and colorless, the more white can penetrate, and the richer the color after refraction and dispersion.
The grading of diamond color is determined by technicians repeatedly comparing the diamond to be graded with the standard color colorimetric stone in the grading environment of professional laboratories.
The whitest diamond is set to D (that is, starting from the first letter of the diamond). The color of diamonds is divided into 1 1 grades, which are D, E, F, G, H, I, J, K, L, M and N in turn.
Cut (cut)
Cutting refers to the angle at which the technician cuts the valve surface and the proportion of each part of the diamond after cutting. In the 4c standard of diamond value measurement, only lathe workers are directly affected by human activities. Although diamonds can be processed into different shapes (fancy) to meet different tastes, the fineness of cutting directly affects the fire and sparkle of diamonds. Rough diamonds have no luster. Only through the precise design and ingenious carving of well-trained masters can the veil of diamonds be uncovered, and the nature of light can be fully utilized, showing a rainbow-like "luster" with flashing characteristics. The scale of cutting depends on whether the brightness and color of diamonds can be perfectly expressed. The perfect cut diamond should reflect the light entering the diamond through different facets, and finally condense on the top of the diamond, blooming with brilliance and flame. Therefore, the value of diamonds with appropriate cutting ratio is naturally higher.
1, ideal cut: represents the standard that only 3% of first-class quality diamonds can reach. This cutting makes the diamond reflect almost all the light that enters the diamond. Elegant and excellent cutting. 2, very good cutting: represents about 15% diamond cutting. It can make diamonds reflect the light of standard grade cutting, but the price is slightly lower. 3, good cutting: representing about 25% of diamond cutting. It is the diamond that reflects most of the light entering the drill bit. Much cheaper than VG. 4. General cutting: It means that diamonds with a roughness of 35% are still high-quality diamonds, but diamonds processed by general cutting reflect 5. Poor cutting quality: This includes all diamonds that do not meet the general cutting standards. These diamonds are cut deep and narrow or shallow and wide, which is convenient for light to escape from the edge or bottom.
