Many merchants have eloquently said that their diamonds are cut in Belgium and cut in Israel, which is purely bragging. Even the GIA people can't tell where a gem is cut. The cut in Belgium is good, but only a large diamond of more than one carat can be cut. If it is not made, it is not cut by Belgium. Russia is also a big country, and they mainly do 30 to 1 carat. Small diamonds below 30 points are basically cut in India and China, due to the cheap labor. Diamonds are sent to the rating after being cut at the processing plant, and all diamonds are re-disrupted and subdivided according to weight and clarity. Therefore, it is purely a matter of fact that it is possible to find out which country a diamond is cutting.
Diamonds, with their hard, rare and unparalleled glare, are the best choice for engagement rings. Putting a sly diamond ring on the white fingers of the beloved bride and locking her heart for a lifetime is what many grooms dream of. But most newcomers know more about it than to slap the lotus flower of the shopping guide staff in the mall. Want to become a master in the rivers and lakes in the short term? Come learn the exclusive collection of IDOIDO!
About a country cut
To say that the origin of the diamond is South Africa, it is purely blown. After the rough stone was graded to the processing plant, it was not known at all. The composition of diamonds is C and the atomic structure is very chaotic. The diamonds produced anywhere in the world are the same, and even professional appraisers can't see the production sites. Diamonds are not like jade, and the place of production does not need to be considered.
About the place of origin
Many merchants bully everyone do not know how to say, this diamond is white, generally the color of IJ, and then give you a preferential price to lead you. In fact, IJ's diamonds are rarely sold abroad, because it can be easily seen with a color chart. But the diamonds in the country are still in the wholesale market, and most of the malls are in this color class.
About color
The most common trap is to say that the diamond is high in clarity. Merchants often advise you to buy a diamond must buy a flawless. But you really use a magnifying glass to not distinguish which VVS1, which is VS1. So the VS above is almost the same, do not have to VVS1, the clarity is slightly worse, the value does not drop much. In addition, the diamond is made into a ring. The clarity of the ring is not the same as that of the bare stone. If the inlay is just covered by the enamel, the clarity of the finished ring will rise by one level, and the price will rise a lot. So be sure to be careful about this trap. The clarity of the certificate depends on the bare stone.
About clarity
In addition, the master must also know how to prevent falling into the trap.
When you finally grow up as a master of diamonds, you can buy a diamond-made ring. With a fancy classic look, the manual fee is about 50-200. The price of the diamond support is generally charged according to the price of gold at that time.
Regarding the certificate of diamonds, the most powerful giant in the world with more than 30 points is GIA (American Gemological Institute). Each GIA International Certificate has a number that lists the various parameters of the diamond, including the indicators they have given for the cut, such as color, clarity, symmetry, polishing, scale data, and so on. And you can find this diamond on GIA's official website. The number on the international certificate corresponds to the number on the diamond. The diamond number is engraved on the diamond's waistline and can be seen with a magnifying glass 10 times. The GIA number is GIA (empty) + 8 digits. The national inspection certificate does not have such anti-counterfeiting measures, and it is easy for the business to shoddy. The national inspection certificate is generally issued by eight diamond testing agencies in Beijing, and it also has a certain power. According to IDOIDO's netizens, these institutions have a very strict judgment on the clarity, but the color is not strictly checked, and it is easy for the business to take advantage of the price. Because of the 50 points of diamonds under equal clarity, the price of D and H colors per carat can be It’s 1,500 dollars.
If you buy a diamond with a weight of 1.00-1.49 carats, a color of G, and a clarity of VS1, then the price per carat is 5900. If the diamond is 1.31, then multiply the weight of the diamond. The price is 5900*1.31=7729 US dollars. It is better to use the exchange rate for the synthesis of RMB. The price of a diamond is divided by weight. Each weight range has a table like the one above. The person who sells the diamond has one copy, and the table is one. When you buy it, you can count it yourself.
The weight basically determines the price of the diamond, the heavier the more expensive. The weight of the diamond is carat, which is the weight of a bean called Carat. This bean is also born with cows, each of which is equally heavy. One carat is 0.2 grams. Since the unit of one carat is too big, everyone divides one carat into 100 points, which is why it is often said that a diamond has 30 points and 50 points.
The fourth style of the Diamond Collection: fixed weight
Clarity refers to the various inclusions contained in the diamond, divided into FL (perfect flawless), IF (internal flawless), VVS, VS, SI, and each grade is also small, such as VVS1, VVS2, VS1, VS2. Clarity should be more than 10 times the magnification of the situation, the clarity of VS (inclusive) or above can not be seen by the naked eye, so you do not have to deliberately seek clarity when buying diamonds.
The third style of the Diamond Collection: see the clarity
Generally, everyone buys round diamonds and pays attention to the eight arrows in the mall. That is to say, with the cutting mirror, eight arrows are seen from the front, and the opposite is eight hearts. It’s just that the eight arrows and the eight hearts are just symmetrical. The most important “proportion†about the cut is not involved. A good ratio can make the diamond more dazzling, so it’s still necessary to look at the proportion of diamonds. Moreover, the so-called eight arrows and eight hearts in the mall are not really eight arrows and eight hearts. The real eight arrows and eight hearts will be marked on the international loose diamond certificate, generally called H&A.
The second style of the Diamond Collection: picking the cutter
The color grades on the international certificate are very clear. There are only DEFG, white (HIJ) and light yellow (KLMN) on the certificate. The scale of the judgment is still wide. In addition, diamonds with a score of 30 or less generally do not have an international certificate and can only be viewed at a domestic certificate.
Color is one of the most important indicators of diamonds. The difference in each color grade on the international diamond price list is much greater than the difference in the clarity grade. The American Jewelry Institute (GIA) will start with diamonds starting with D, E, F, G, H, I, J... X, Y, Z. means from colorless to pale yellow. DE is basically colorless and the price is very high. FG, partial to colorless (very white), the price is also very high (most foreign diamonds are above this color). H, I, J are white (but already yellowish), and the diamonds in the domestic market are basically this color. As for the diamonds with the following colors in K color, advise the sisters not to consider the rings.
