The first step is to study the rough diamonds in great detail, which is a rough diamond by a specialist or a marker. You can see on the rough stone and determines how the stone can be cut at its best. He takes into account the structure of the stone and the impurities that are still there. He chooses, for example, make two small stones of a large stone. It is very important that the cuts of the diamonds so that there is so little lost as possible. Finally, the specialist in rough diamonds literally mark the diamond.
The first and oldest form of diamond cutting is called cleaving. Until the Middle Ages this was the only technique. The Indians, Greeks and Romans to study their crowns and jewels with (almost) for rough diamonds. Despite this, they knew that the main support for diamond cutting diamond was ... ..!
Cleaving is the first form of diamond. The irregularities of the crystal and impurities are removed during this phase. Sometimes this means that the needs of a knife to split rocks in two or more pieces, of course taking care not to lose a stone.
Cleaving demands crafts. The diamond rod is fixed with a quick-drying cement. Then take another diamond blade, and uses it for the first nick of diamonds. (In these days often makes a laser that nick as well.) Then put the steel knife blade knife in the nick, and with a strong blow of the hammer, the stone Cleaves.
Artisans often cleaving compare diamond cleaving wood, because, as with wood, it is important to success along the grain.
A laser is confronted with the diamond its worst enemy: heat. The laser beam burns its way through the diamond. Interestingly, a laser beam is not hot in itself: only when the temperatures rise lightning strikes an object.
Diamond sawing is what the word implies: simply that the stone is divided into two parts. But of course this is not done in a disorderly manner. Studies of stone sawyer and should decide which method to use. Otherwise, you could see that the two halves appear to be useless. Could be compared to a carpenter who has to take into account the piece of furniture that will go before a board saws.
When diamonds are sawn, the first stone was placed to the needs: pasta with a special stone is placed in a dop (holder). The diamond cutter of the Declaration of Principles is mounted on a saw. The saw is a saw blade coated with a thin mixture of oil and diamond dust. The speed of rotation of the disk is on average 15,000 revolutions per minute. Sawing is a very slow process of 2 mm per hour at most. It can take days or weeks before a big stone is sawn. Imagine how slow it was in the past, when it was sawn with diamond wire, iron or copper coated with diamond dust. A job for a patient and meticulous craftsmen! In recent years, lasers are frequently used for sawing diamonds, which is actually much faster.
Before polished stones, most of them paid a visit to the Brüter. A diamond will get their first form when bruted. The belt is created - ie, the area that marks the border between the top (crown) and bottom (pavilion) of the diamonds. Brüter the belt becomes a perfect circle. Also, to get rid of the rest of the damage and at the same time limit the loss.
