ダイヤモンド

In a store window on dark velvet under a bright electric light, all diamonds sparkle in the same way. And we are not talking about size and the number of facets. Although size matters for diamonds, you should not only look at the size, but also the color and clarity of the stone. So, you have decided to buy a gemstone or an item with it. On the tag or in the certificate it says: "3/6". What each of these numbers means, let's talk about in this article. Deciphering Let's start from the beginning. Diamond characteristics 3/6 means that the stone has color 3 (this parameter is indicated first) and clarity 6 according to the Russian diamond certification system TU 117-4.2009-2002. But, as already mentioned, size matters, and the TU takes this into account. For stones with 57 facets weighing up to 0.29 carats, there are 7 color and 9 clarity parameters. If the mass of the gem is from 0.3 carats and higher, there are 17 color grades and 13 purity grades. Fig 1. Color of a diamond …

At first glance, most colorless diamonds look like twin brothers. And this is not so much due to the unprofessionalism of the beholder as to the imperfection of human vision. Therefore, when choosing a single stone or diamond jewelry, it is necessary to carefully read the characteristics on the product tag or in the certificate. For example, they say that the color and clarity of a diamond correspond to 3/3. What do these numbers mean for the buyer? Deciphering There are several systems of diamond certification in the world. In our country, TU 117-4.2009-2002 is accepted. To evaluate a stone, jewelers use a special table. Stones weighing up to 0.29 carats have 7 grades of color and 9 grades of clarity, while stones weighing from 0.3 carats have 17 grades of color and 13 grades of clarity. There is also a difference in the grading of stones with 17, 33 and 57 facets. But below we will consider only round brilliant-cut diamonds with 57 facets, since such stones are the most com…

Fig 1. Dancing diamond They say that for the most part jewelers are conservative people and are not partial to any innovations. But when innovations in jewelry do happen, they make a sensation, make the whole world stand still in mute admiration and then rush to the stores. The "dancing diamond" produced just such an effect a few years ago. No, this is not some new kind of cut diamond. A special cut and a special mount in the cast make the stone "dance". Mounting in the setting There are four main types of stone mounting in a setting: krapanova - the mineral is held on the setting with the help of "paws"; corning - the stone is fixed directly in the metal with the help of corners; blind (rim) - the gem is fixed in the frame and crimped by it around the entire perimeter; special group. Each of these groups has many subtypes (we have discussed this issue in detail in the article "Types of stone setting in jewelry"), and the most common ones are krapanova and blind. B…

Fig 1. Diamond Heart of the Ocean Competent Hollywood screenwriters are good at making inanimate things full-fledged characters in a story. In the future, the viewer invariably associates these objects with the movie where they shone. For example, what movie brings to mind a glove with long iron claws-blades? "Wolverine," of course! Well, or "A Nightmare on Elm Street" - depending on the length of the blades. A gold ring with a glowing ligature? "Lord of the Rings," of course. The red and blue pills are from "The Matrix," and so on. And how about a pendant with a blue stone cut in a heart shape and framed by diamonds? Yes, that's right - it's the blue "Heart of the Ocean" diamond from the touching story of the love of a young aristocrat Rose and a penniless artist Jack that erupted aboard the doomed Titanic. What is true and what is fiction in this story? Does the "Heart of the Ocean" diamond really exist or is it a figment of the imagination of the authors of the picture? …

They say that an important criterion for gemologists when evaluating a diamond is the cut of the stone. And they are right. Imagine that you are looking at two stones with the same characteristics - both VVS (Very Very Slightly Included), i.e. clean, almost without defects, very small inclusions can be seen only in a microscope. And the shape of the cut is the same. But one of them shines with stellar brilliance, mesmerizes and beckons, and the second one next to it looks like an unattractive poor relative, in which there is neither strength, nor play, nor brilliance, nor, to put it bluntly, special beauty. And it seems to be smaller in size than its luxurious counterpart. What is the difference between the "twins"? It lies in the quality of cut, the notorious "ABVG" according to the Russian TU 117-4.2099-2002 and the 4th C (CUT) according to the international GIA system. Cut quality What is diamond cut quality and why is it so important? Nature creates a diamond, endowing i…
