Rules for buying diamond necklaces
1. Tangent: Tangent classification is an objective measure of the refractive properties of diamonds (that is, we generally think it is bright). When the diamond is cut in a proper proportion, the light will be refracted and reflected from the top of the diamond to the greatest extent. In 4C, cutting can be said to be the most important feature, because it directly determines the brightness of a diamond, and the cutting of a diamond will affect how big a diamond with the same carat weight looks. The higher the cut grade, the bigger the diamond looks. Cutting is divided into five grades, from high to low: excellent > very good > good > average (average) > poor (poor).
2. Color: The main component of diamond is C, and when it contains a small amount of N (nitrogen), it will produce yellow (this yellow mainly tends to dark tones, similar to brown; Distinguished from bright yellow, such as gold diamonds belong to colored diamond). Therefore, the less N element content, the colorless color and the more expensive it is. GIA classifies diamonds as D-F (colorless) > G-H (almost colorless) > I-J (almost colorless) > K-Z (perceptible color), and the values decrease from left to right.
Maintenance points of diamond necklace
1, when doing housework, don't get oil or bleach on the diamond ornaments. Oil will affect the luster of diamond ornaments. Bleach will not damage the diamond, but it will make the inlaid metal fade or produce spots, which will make the diamond ornaments lose their luster.
2. Diamonds have strong adsorption, that is, they are easier to blend with oil than other gems, so it is difficult to remove fingerprints or sweat stains after a long time. Almost all lotions and cosmetics contain oil, so it is absolutely necessary to wear diamond ornaments after wearing perfume.
3. Always check whether the inlay foot is firm and reliable, and whether there is any knock-on phenomenon. When wearing sweaters or knitted clothes, pay attention to whether the diamond ornaments worn on your body have been torn off. After all, diamonds are not cheap. When not in use, keep it properly and put it in a fixed center for easy access.
