knowledge and the correct identification of cuts of gems is often relegated to the expertise of gemologists or industry experts. We try to make things clear signs, synthetic, so enabling them to express those words correctly.
There are four main types of cuts: brilliant cuts, step, briolette and cabochon, latter being used strictly for colored stones .
The diamond can be cut in an incredible variety of shapes, thanks to its physical characteristics. It 's the hardest gem be the number 10, which is the highest in the Mohs scale, so that to be scratched using powder diamond itself.
The term " brilliant " wrongly used to indicate a round brilliant cut diamond is the most common example. Diamond indicates the material, and indicates a round brilliant cut round shape that has 57 facets +1, ie the apex. The table below, or apex, has ideal size when it is barely visible under 10x magnification.
The first attempts to cut the diamond, which comes in a raw form of an octahedron, were simple polishing. When the experience and resources Technical permitted, they progressed to the sanding of corners and edges, so as to obtain the first form of cutting known as "old cut" or "Peruzzi," named after the inventor. This cut will be held in any account, however, the effects of light reflection and the ultimate goal was just to give the object that looks good. We
the birth of a brilliant cut Marcel Tolkovsky that, in 1919, pointed out the ideal proportions related to diameter , distance pavilion crown and table and belt , to obtain the phenomenon of total reflection of light, ie, the sparkle that you see looking at the table of the stone.

not forget also that the gemology is a recent science and optical instruments available for analysis have been developed in parallel with the discoveries of the last century. It is then very easy to find inclusions veils and carbon obvious since the table in the buds cut in earlier studies Tolkovsky.
These are the most common cuts that emit flashes of the most unique and enhance the effects of brilliance.
The cuts include the step emerald cut (rectangular with rounded edges), loin (square), baguette (rectangle), taper (trapezoidal) tet de veau (or head bull, given the typical trapezoidal shape with the two upper edges rounded) triangle .
Unlike earlier, these cuts bring out the best "color" stone, hold it, with games of reflection, the dye inside the walls themselves, and hint at some tables beamlines.

is not unusual for the same purpose, they should use both types of cutting. One enhances the effect of the other and, together, these optical toys focus attention on jewelry design.
The briolette cut part of a three-dimensional teardrop or oval shape to which we apply a series of faccettature to increase the brilliance of the gem. In the past it was used for large carat diamonds also, but it can also be applied to colored gems.
The cabochon in the shape round, oval, heart, and shuttle drop, with a rounded top surface and a lens in the lower . It is intended to exhaustively gems of color because the color holds. Typically, you select for this rough cut is not particularly valuable.
There are also mix of cuts like bufftop , which presents the table cabochon and faceted pavilion, or ; fire rose , which has a hexagonal base designed by brilliant cut Gabriel Tolkosky , the grandson of the inventor of the brilliant cut. There are many more but, in principle, those above are the most common.
