Rings are some of the finest jewelleries to give to a loved one for a special time such as a birthday, an anniversary, a wedding proposal, or Valentines. Simple and modern engagement rings UK, diamond stud earrings, jewelled necklaces, and bracelets are a classical favourite as well as their more intricate counterparts.
Seeing the valuable gemstone, you might reflect on how incredible nature is to have the capability to form the stones; extremely detailed shape. However, in truth, raw diamonds look like rough crystals or shapeless blogs. The elaborate forms of the stones that attract the buyer are not made naturally. To make diamonds gem-worthy, special approaches in cutting and polishing the stones are needed.
1. Cleaving
This is the initial stage in carving out the gem from a diamond rock. The cutter first locates the weakest part of the diamond, normally along the rock’s tetrahedral plane. He then produces a wax or cement mold to secure the diamond to prevent the rock from shifting. After securing the diamond, he then cuts a sharp groove along the plane with either a laser or a special cleaver. He places a sharp, steel blade along the groove and forcefully strikes it. The force of the blow splits the rock in two pieces.
2. Sawing
At times, the diamond rock does not exhibit a plane of weakness, rendering the process of cleaving virtually unviable. In this case, the diamond rock needs to be laboriously sliced up with a phosphor-bronze blade that rotates at 15,000 rounds per minute. As an alternative, powerful lasers are also used to saw and slice the extremely dense and hard rock. Prior to cutting, the cutter determines which section of the rock becomes the table and which section is the girdle. He proceeds with the cutting after mapping out these locations.
3. Bruiting
Once the diamond is cleaved or sawed, it is time to give it its shape. The cutter uses small stick-like instruments, similar to small chisels, which are impregnated with abrasive diamonds. That’s right, he uses diamonds to cut diamonds. First, he secures the diamond rock in place by immersing it in a small bowl filled with cement. The diamond rock is carefully placed in the cement in such a way that only one corner is exposed. Then the cutter expertly rubs or whittles the rock with his equipment to the correct shape. In mechanical bruiting in which a machine is used to shape the diamond, the diamond is stabilized in a lathe. Another diamond is rubbed against the rock to create the basic shape of the gem.
4. Polishing
The last phase of converting a rough diamond into a gem is polishing. This is the step in which the cutter has to be extremely careful so he can produce facets of the right size and arrangement. The cutter initially holds the bruited piece on an arm above a rotating polishing wheel. The surface of the wheel is coated with an abrasive diamond powder. As the wheel is switched on, he touches the surface of the bruited diamond on the wheel to produce the facets and to fine-shape the gemstone. The diamond powder on the rock also smooths out the diamond as it is pressed against the wheel’s abrasive surface.
Finally, the gemstone is rinsed in clean water and subjected to a treatment of transparent coating to protect its surface from dust, oil, and grime. Without this coating, the gem rapidly becomes dull and lifeless.
