Today bruters have "super bruters' at its disposal, the machines that appear around a double. Two diamonds also set in DOPS, rotating in opposite directions and the beasts this strip. Only a couple of years ago, the diamond be placed in a traditional lathe. Brüter then the five of diamonds shpae using another bruting diamond on a stick. There winches, all this was done by hand. The two diamonds are placed on a stick and rubbed vigorously yet meticulously against one another. Brüter required to wear leather gloves to protect your hands.
Polishing is the last stage in the process of diamond cutting diamond is now the shape and brightness. Polishing is the creation of small planes on the diamond, which are called facets. This is done in two phases. First, 4 facets are polished at the top (crown) and bottom (pavilion) of the diamonds. The result is what we call the cross work. Then the diamond is brillianteered. This means that extremely accurate polishing of other facets in the work of the cross ribs. To shine your diamond, each facet to be polished at right angle to it, use a polish turns horizontal disk, with oil and diamond dust. There are special pliers adjustable DOPS that enable the position of the diamonds at different angles on the disc.
Polishers working five diamonds at a time, so they need to concentrate very hard. A diamond can lose much of its brightness value or a buff or polish too bad angle. Experts will notice immediately whether or not a diamond polished properly.
When the diamond cutting, centuries of manpower and modern technology go hand in hand. Therefore, the cutters of diamonds are experts at both levels.
As mentioned before, diamond cutters, and especially how the jewel polishers eventually look: the "cut" of the stone. The most famous is the "bright cut", which always consists of 57 facets plus the table, which is the large flat facet on top of the diamond has 32 facets on the crown and 24 in the pavilion. The shape of cut and polished diamond was given name. Other cuts are very popular: marquise, pear, oval, baguette, Emerald, Heart and Princess.
We have already seen a diamond material is rather rare. Requires great effort to mine, then there is still a large amount of work necessary to convert the raw stone a sparkling diamond. But diamond traders, how do you determine the value of a diamond? How do I know, for example, if you want to buy diamonds that are really true? And not a piece of land instead of glass? And now, you know that there are no cracks in the diamond invisible to the naked eye? The answer is the certificate. It is important that both buyers and sellers that such certification, which gives a kind of vital statistics of the diamonds. Prevents surprises.
A diamond does not obtain certification immediately. During a whole week all sorts of expert evidence and examine the stone. Tester, of course, you never know who owns a diamond you're testing. But what exactly is the value of a diamond determined? What do experts test and measurement?
First, it will be authenticity. Diamond possesses a number of properties and features. Absorbs light in a particular way, is a good conductor of heat and has a known specific gravity. All this can be measured with special equipment. Only real diamonds pass the test.
You can test if your mother is real diamond. Take a pen, draw a line on a sheet of paper and place the stone in it. If you cannot see the line in the diamond that the mother is lucky. If you still can see the line, it is likely to be ground glass or something. As a diamond reflects light so strongly, the light cannot penetrate the line and remains invisible.
