It is also the happiest moment to witness a girl, and there are many details to pay attention to when buying a diamond ring. It is a challenging thing for boys, so for some common problems in buying diamond rings, today we will answer questions for everyone!
1. Which of the 4C diamonds is more important?
The value of diamonds is determined by 4C, so 4C is very important. From the perspective of cost performance, the selection of diamonds is still focused. In the case of certain size, it is first recommended to consider the cut of C. The degree of excellence of cutting directly affects The fire of diamonds, so we often say that cutting is the second life of diamonds, secondly consider the color of C, the color from DZ, the closer to D color, the whiter the diamond, it is recommended to consider the clarity of C, to VS or above. Well, because the clarity is not as obvious as the naked eye, there is almost no difference from the outside. If there is a high demand for the purity of the diamond, then it is another matter.
2. Is it the carat to protect the value?
For us, diamonds of any size are preserved, but whether your diamonds are valued or not depends mainly on the purchase price of the diamonds. In the general market, diamonds are mostly 30 points, 50 points, 70 points, and 1 carat. It is generally believed that as long as one carat or more of diamonds can preserve the value of collection, this actually ignores the 4C knowledge points we introduced earlier and measures the value of diamonds. C is indispensable, each one is very important, such as a 1 carat color M color, clarity P1, cut 3G and a 50 minute color D color, clarity VVS1, cut 3EX diamond, comprehensive consideration Of course, 50 points is more valuable.

3. Is there a laser laser code for a bare diamond greater than or equal to one carat?
In order to maintain its perfection, diamonds of 1 carat and above will not be laser coded unless specifically requested. However, the diamond certificate of one carat and above has a sketch of the clarity. The type and location of the icon marked with the 是 is the only one corresponding to the diamond, and the identity of the diamond can be determined. If you are not at ease, you can ask the professional to help you check whether the 净 of the clarity sketch corresponds to the 瑕疵 of the diamond.
4. Where is the origin of the diamond? Is it a South African drill?
In fact, the original origin of diamonds is difficult to trace. The reason why South Africa is famous is because South Africa has produced several large diamonds, such as "South African Star" and "Cullinan". At present, the main producing countries are Australia and Russia. 70% of the world's diamond embryos are controlled by De Beers (DTC), so the origin of the embryo is difficult to define, and DTC distributes the embryos to several world's largest cutters. Belgium, Israel has the best cutting process.
5. What is diamond fluorescence? Does fluorescence have any effect on the value and aesthetics of diamonds?
Diamond emits visible light under ultraviolet light. This property is called ultraviolet fluorescence, or fluorescence. About 35% of the diamonds are fluorescent. The most common fluorescent color is blue-white, with a ratio of up to 97%. In addition, there are other rare fluorescent colors such as orange and red. That is to say, under natural light, the fluorescence is almost imperceptible, and unless there is a strong fluorescent diamond in the strong summer sun, the naked eye can feel the presence of fluorescence. Except for this case, fluorescence has no effect on wearing. Not all diamonds have fluorescence. According to the ratio of three fluorescence intensities, the fluorescence intensity of the sample is divided into strong, medium, weak and no. Although fluorescence is a natural indicator, it is only an auxiliary parameter, which has little effect on the value and aesthetics of diamonds.
6. Which kind of precious metal material is better for diamond ring? Why is the 18k gold diamond ring discolored?
A: At present, the most common diamond ring materials on the market are generally 18K gold and platinum (Pt) materials. 18K gold contains 75% gold, which combines 25% of other metals. Therefore, 18K gold still has strong gold ductility and is easy to shape. It is characterized by various shapes, and its hardness is greatly enhanced and it is not easy to be deformed. It is very suitable for inlaid jewelry, and it can more flexibly shape the diamond ornaments of different shapes and styles.
However, the color of 18K gold jewelry mainly depends on the ratio of 25% of other metals. It is generally yellowish white. For the beauty and durability of jewelry, it is often plated on the outer surface of the jewelry, so we see the bright white appearance of the ring. It is actually a coating. Some behaviors in daily life will cause the coating to wear out. When the coating is worn, the true color of the metal will be exposed. This is a normal phenomenon. As long as it is a product that has passed the quality inspection by the quality inspection center, the jewelry content should be no problem.
Platinum (Pt) materials are generally not easy to change color, but the material is softer inlaid diamonds may have the risk of falling diamonds. In short, precious metal materials have their own strengths. If it is inlaid jewelry, it is recommended to choose 18K gold material to be relatively strong.
