• Precious Stones

When precious stones are found in mines, they don't look half as dazzling as they should look. Gems are finely cut, shaped and polished to give it that mesmerizing stunning and impressive look. The method of cutting the stone is known as gem cutting or lapidary. This process was started in the early 1300s in Venice. Later in the 1400s this method was used in Paris and Bruges. 800-434-0257

• Four Basic Styles

There are four basic styles of gem cutting, namely tumbling, faceting and carving. The precious stones should be cut so well that they mirror and reflect the light that falls on them. If the gem has not been cut or polished well, it destroys the beauty and the shine of the stone. For example, an alluring diamond, if not polished and cut well, will not be as valuable, rich or worthy compared to a well polished diamond.

• Lapidary By Sawing

The gem cutter or a lapidary, also known as lapidarist begins the process of lapidary by sawing the gem. The gem from the mine is first cleaned with oil or water, to remove the residues present on the stone. The stone is then sawed with a thin circular blade. One can use different sizes of blades, depending on the size of the stone. Sawing helps remove all the debris and chunks of mud stuck to the stone. The second step is grinding the stone.
