How diamond is cut

We all know that the price of diamond relates how he is cut. However, most people do not know how cutting actually happens.

How diamonds are cut (manufactured)

When a diamond is operated, it is not glittering and bright, is not in a round or square shape. A mined diamond is called a rough and is usually just, rough research and somewhat shaped egg. It passes through several stages in the process of cutting and finishing until it was ready to be placed in a beautiful piece of jewelry.

Marking and planning

Marking and the planning process is what determines what form each diamond will be cut off in. Expert Planner examines the stone and decides the form which will make the color look the brightest, will conceal the natural imperfections and him be shaped without losing too much of the stone. This planning enables a cut that maximize the value of the stone.

Cleavage and sawing

Cleavage and lumber are the two methods accepted Cup. For he cliver, the cutter discovers the nature of the "grain" of the lens Canada and decides where the stone should be cleaved. A line where it should be cleaved is cut it with an another diamond, and then a chisel and hammer are used to divide the stone. Cleavage is usually used with the greatest sketches which will be cut into several small diamonds

It can also be cut with a diamond saw, disc slim with a blade coated in diamond dust. They can only be cut with an another diamond, so that the blade is cutting the rough, it accumulates and reuses formed from diamond dust. Sawing is a much more accurate method of cutting and present a limited risk of shattering diamond, however, it is also more expensive than the cleavage. Lumber is used most often.

Lasers are sometimes used for cutting. The process is very accurate, but much more expensive. Lasers can also be used to cut letters or symbols on the facets of the diamond.

Bruting

Bruting is the process that gives the diamond shape of cone bottom. The stone is set in a tower and spun. As it is spinning, an another diamond held against his side, she smoothing cone-shaped. Bruting is also sometimes as "round", or "girdling". The particular style cut (round, Princess, etc.) will play a role on how steep girdling will be.

Faceting

Facets are aircraft that the diamond is cut with that give brilliant lustre. Facets are placed on the stone according to its form to maximize the way light is reflected by the diamond. An important facet is placed on top, called the Table, and then a variety other facets are placed everywhere in the rest of the diamond. Facets are cut by grinding of diamond at an angle against a blade covered with dust from diamond to the desired size and angle is reached. During the stage of faceting, diamond becomes a reality in the form of well known diamond.

Placing and polishing

In this last step, the diamond is placed in a clamp and polished with an another Blade coated in diamond dust. This blade does not contain the same amount of roughness than other blades. Think of the difference between a metal and glass paper coarse file fine. This gives the diamond one finished brilliant versus a striped.

The ideal cut

In 1919, mathematician Marcel Tolkowsky has used a series of mathematical equations to find the ideal cut for a round diamond that would maximize the way it reflects light. Today, classification of a diamond and how it is cut (manufactured) is generally compared to the definition of a perfect diamond certification laboratory. Although the years diamond cutters have continued to study and seek to improve the perfect cup, many of the ideal cut proportions that tolkowsky statement remain the same.

When the Cup is ideal, therefore the price of diamond.
