What are you buying when you buy a GIA loose diamond?

Speaking of GIA, probably people who have been in the jewelry industry should have heard of it. Most people can also speak up to two points, such as "4C", "fluorescence", "laser code", and better understand. A little person will also know "cream drill", "coffee drill", "miscellaneous green diamond". But do you think this is all GIA? of course not.

Some time ago, one of my classmates consulted with me to buy a diamond. I thought that it was also an old classmate, and I got a quote for him by the goods. However, like most of the asking guests, there is no following. About a month later, he sent me a photo of the certificate, accusing me of not being friends, saying that the price he bought at someone else was more than two thousand cheaper than my offer. It is a 1ct diamond. The insiders know that the profit of wholesale is only a few hundred. I heard that he is more than two thousand cheaper than me. I know that there is absolutely a problem. Sure enough, when I saw the certificate, I said to him, "You better go to the national inspection and check it out and tell me." A week later, he told me that the re-examination results fell two levels, and I told him clearly that his certificate was an obvious fake certificate. Because the certificate is written according to the date of the day, month, and year, and it is all figures, it is the reverse of the way we usually use the date in our country, but in fact, the way the US remembers the date is the month, day, and year. And like the date on this certificate, the month must be a word instead of a number. So I saw at the first sight of the certificate that this is definitely a fake certificate, and it is not necessary to look at the goods. Only this point is enough to judge. Then he went to contact his seller, naturally there is no news.

I can only comfort him. "You just have to deal with a few levels of shoddy. Fortunately, it is not a drill or a synthetic drill. Eat a long and smart one." Some people can't even spell out the full name of GIA. They only know about diamonds in Baidu for a few days on the Internet. They feel that they know diamonds and can go to the market. I don’t know, it’s because this mentality makes so much. The liar has a chance to be awkward.

After reading this example, are you still reading this article, do you still know that diamonds know GIA very well? The above is just a very bad way of fraud, can only lie to my friends, who barely understand diamonds. More sophisticated means in Shenzhen, where diamond prices are increasingly transparent and price wars are already hot, are everywhere. Some people sell real diamonds, which are also true certificates, but the certificates are different. This is the so-called "proof card" in the industry. Please see the following set of data (source: GIL Hong Kong Lab):

In the 4C of diamonds, cutting is the most easily overlooked, but we can see a lot through cutting. No one of the measured data of the above diamond can correspond to the certificate. Basically, it can definitely be a "certificate". When the goods are fraudulent, the seller will choose high color and high clarity. This kind of goods that can blur other factors is subtly lower than the certificate by one color level or clarity level. Subtle, not well-trained professionals are difficult to distinguish, and for diamond wholesale, the industry profit is already low enough to "a level difference can be several times the normal sales of others", this is for Oita This is especially true for diamonds. The picture below is a Rapaport quotation that everyone is familiar with (Source: Baidu Encyclopedia, we can also see the date record of "Month, Day, Year" from the map):

As we all know, Rapaport quotation is only three items of weight, color and clarity. In the industry, the goods are obtained by multiplying the reference price of the quotation by the discount. The discount is the “operable part”. Not to mention the difference between the best 3EX and "non-3EX", "milk, coffee, green" and "fluorescence" are also commonplace. Just the color and clarity of the diamond itself can be countless. "Dark pit." The effect of the diamond's internal inclusions on the clarity of the diamond is reflected in six aspects: quantity, size, position, contrast, number of images, and traits. For example, two diamonds that are also VS1, one in the middle of the table top, and the other in the upper waist are inlaid occludable range, then the latter must be more expensive than the former; for example, the two are the same SI1 diamonds have the same body position, but a strong contrast (such as the common white feather split, different from the white we say white diamond, we usually say that the white diamond should be colorless diamonds accurately) The other is just a common feather split. The former is visible to the naked eye because of the contrast, and the latter is clean. The diamond is also inevitably more expensive than the former... and so on, and all of them are A few simple grade letters can't be expressed completely, but these differences will be reflected in the price.

So, let's go back to the article title, what are you buying when you buy a GIA loose diamond? Although the 4C classification provides a quick passage for ordinary people to understand diamonds, diamonds are minerals that have naturally formed over hundreds of millions of years. It does not grow according to the rules set by human beings. There must be many contents that cannot be covered by the 4C system. That's why the jewelry industry needs so many highly trained professionals.

If you don't understand diamonds yourself and are afraid of falling into a trap, then finding a professional and responsible service provider is the best option. As mentioned above, the competition between the upstream markets of Shenzhen in the jewelry industry has already become fierce. The familiar people also know that in addition to the goods that the service providers buy themselves, the foreign supply resources are actually shared by everyone. In other words, everyone in this game is playing cards, who can play the best, it must be the most efficient and professional service, and not the lowest price. The profit of this wholesale link is not only compressed to the lowest level, but even completely transparent. In this situation, the price war is dare to be played. The author does not take the malicious speculation. I am afraid that only those who are fraudulent. On the other hand, in such an environment, we can adhere to our own principles and not give customers a "dark disease" diamond. We can tirelessly explain to customers that science and technology guides customers to establish correct diamond values. Such enterprises are worthy of admiration.
