Diamonds: PROCESSING BEFORE IT GETS TO JEWELLARY STORE
« on: March 09, 2015, 09:15:17 AM »


Th­ere are special techniques that are used to cut and shape a diamond before it gets to the jewelry store. Diamond cutters use these four basic techniques:

1. Cleaving - To cut a rough diamond down to a manageable size, the cutter must cleave it along the diamond's tetrahedral plane, where it is the weakest

2. Sawing - Sometimes, diamonds have to be cut where there is no plane of weakness, which cannot be done with cleaving.

3. Bruiting/Cutting - This technique gives diamonds their shape. When diamonds are cut by hand, the technique is called bruiting -- cutting refers to bruiting by machine.

4. Poli­shing - To create the diamond's finished look, the cutter places it onto the arm above a rotating polishing wheel. The wheel is coated with an abrasive diamond powder that smoothes the diamond as it is pressed against the wheel.

Be gentle and you can be bold but also let people feel, the steadiness of your resentment;
be frugal and you can be liberal;
avoid putting yourself before others and you can become a leader among men.
