Crystals
Crystals benetti - a union of art and modern technology, traditions and scientific achievements, experience and commitment to excellence - a precise calculation and luxurious shine to each face.
The secret of the unique crystal benetti their perfect transparency, to get that is only possible under certain physical and chemical conditions (composition, they contain from 30% PBO, resulting in crystal optically pure) in conjunction with the special methods of cut corresponding to the level of processing of precious stones.
According to experts, the glass can be called the word "crystal" if it contains from 6% to 36% lead oxide.
The modern production of crystal used in addition to lead oxide and oxides of other elements of the periodic table, - oxides of barium and zinc, which have similar properties.
In accordance with the European standards regarding the chemical composition of the crystal mass LABELS "Crystalline" ("crystallin") - corresponds to the content of 1-15% lead oxide, the inscription "Crystall" ("Crystal") - is a more expensive item, as in this Product is present 16 - 23% lead oxide, but there are also more concentrated crystal products - "Full Lead Crystall" ("lead crystal"), where the composition of lead oxide already reaches 24 to 30%.
32% - this is the optimal amount of lead that can be entered into the formula of glass without the risk of losing its luster, strength and reflection properties.
Original crystals benetti different facets of perfection. The height, width and angles of the faces always the same - they are found strictly in one point.
All benetti bounding the crystals and polished machines extreme precision prismatic comparable with diamond cut and then processed manually. All this creates a product with the highest light performance. Each crystal is flat and smooth polished, has no chips, turbidity and bubbles over each vnutri.Rabota crystal assumes preliminary computer 3D-design and optimization models to determine the most effective number, size and shape of faces.


Symmetry is one of the most important aspects of cut crystal. Perfect symmetry is verified with mathematical precision provides the best display of brilliance. Internal luster crystal - is the percentage of incident light that comes back. Objective diamond cut is to achieve maximum internal reflection. When the light beam enters the crystal, it should withdraw from it properly, and not down, or in any one furthest point.
Crystals benetti have strictly established forms cut.

In the design of cut crystals adhere to two main factors. One of them is the refractive index of diamond (RI) is equal to 2,417, is quite high compared to other precious stones. The refractive index influences the amount of gloss, the amount of light that returns reflected from the faces. Another factor important in the design of the cut - a variance, or the ability of a material to the division of the color spectrum that a diamond is quite high 0.044. Flash dispersion create brilliance, visible only after cutting.
