Engagement Rings How Diamonds are Cut
Rings are some of the most excellent jewelleries to offer to a special someone for a special event such as a birthday, an anniversary, a wedding proposal, or Valentines. Simple and new different engagement rings, diamond stud earrings, jewelled necklaces, and bracelets are a traditional favourite in addition to their more expensive counterparts.
Looking at the valuable diamond, you might reflect on how marvelous nature is to be able to form the stones; extremely detailed shape. However, in truth, raw diamonds look like irregular crystals or shapeless blogs. The elaborate forms of the jewels that appeal to the buyer are not made naturally. To make diamonds prized gems, a set of unique techniques 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 identifies the weakest part of the diamond, typically along the rock’s tetrahedral plane. He then creates a wax or cement mold to hold the diamond in place. After holding the rock, he then cuts a sharp groove along the plane with either a laser or a cutting tool. He places a steel blade along the groove and strikes it with great force. The force of the blow splits apart the rock in two pieces.
2. Sawing
At times, the diamond rock does not exhibit a plane of weakness, making the process of cleaving virtually impossible. In this case, the diamond has to be laboriously sliced up with a phosphor-bronze blade that rotates at 15,000 rounds per minute. Alternatively, powerful lasers are also utilized to saw and slice the extremely dense and hard rock. Prior to cutting, the cutter determines which section of the diamond becomes the table and which section is the girdle. He proceeds with the cutting after choosing out these sections.
3. Bruiting
After the diamond is cleaved or sawed, the cutter is ready to give it its shape. The cutter uses small stick-like instruments, somewhat akin to small chisels, which are impregnated with abrasive diamonds. That’s right, he uses diamonds to cut diamonds. First, he holds the diamond rock in place by placing it in a small bowl that is filled with cement. The diamond rock is carefully placed in the cement so that only one corner is exposed. Then the cutter carefully rubs or whittles the rock with his equipment to the right shape. In mechanical bruiting in which a machine is utilized to shape the diamond, the diamond is placed in a lathe. Another diamond is rubbed against it to make the rough shape of the gem.
4. Polishing
The final step of converting a rough diamond into a gem is polishing. This is where the cutter has to be very careful so he can make facets of the right size and position. The cutter initially holds the bruited piece on an arm on top of 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 make 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.
Lastly, the gemstone is washed in clean water and subjected to a treatment of transparent coating to shield its surface from dust, oil, and grime. Without this coating, the diamond easily becomes lifeless.
The diamond on diamond earrings, rings, and other jewellery came a really long way from its raw form.
