From time immemorial people strived to enhance their beauty with the help of different articles of jewelry and precious gemstones. But at the early stages of human civilization people were certainly not spoilt for choice in terms of the selection of gemstones. As far as diamonds are concerned, it took people a very significant deal of time to learn the ropes of diamonds mining and diamonds cutting.

Certainly there was then no extensive knowledge in terms of diamonds manufacturing and the means to reach the ultimately pure diamond color and clarity. Besides, the primitive equipment and undeveloped processing methods employed earlier did not create the conditions necessary for efficient diamonds manufacturing and the elaboration of a multitude of methods of diamond cut and refinement. At early times a few simplest types of diamond cut prevailed and they were generally rather uniform.

Lucky for diamond fans the branch of industry of diamond manufacturing is very highly developed nowadays and this fact creates grounds for the production of a staggering diversity diamond cuts, assuring perfect diamond color and clarity. The color range is quite spectacular indeed.

In the sphere of diamonds manufacturing the universally accepted carat scale is used for weighing diamonds. Generally, diamond carat weight is measured with the help of a rather complicated formula, the component parts of which are average diamond diameter squared and depth (both expressed in mm), cross multiplied with the conventionally accepted size-weight conversion factor which is 0.0061.

Speaking of diamond color and clarity, it seems necessary to point out that the latter it judged in reference to the presence of blemishes and the level of inclusion. These factors are different from one crystal to another. Such inclusions and blemishes that are invariably present in diamond, it being a natural material, don't bear, however, any negative connotation, being perceived as identifying characteristic features. It stands to reason that fewer and smaller inclusions are desirable, so that the diamond color and clarity remains untarnished.

The next diamond characteristic to speak of is diamond cut. It is actually the ratio of the diamond depth to its diameter. If the diamond is properly cut and well proportioned, it becomes a fascinating sight to the eye. In this case the beam of light does not escape through the sides or the bottom of the diamond, but it rather reflected directly to the eye and accounts for the dazzling brilliance.

Modern materials and equipment are now used in diamond manufacturing in order to contribute to the production of high quality diamonds that would meet the dictates of popular tastes. Curiously, extensive research into the matter of perfect diamond parameters is still being carried out in the specialized laboratories. The effect certain peculiarities of diamond cut have on diamond brilliance is still being widely studied.

One of the most shocking results that have been obtained in the course of this intensive scientific research is the fact of the absence of the so-called "ideal cut". This notion has been widely used in diamonds manufacturing in reference to the perfectly calculated diamond proportions that would guarantee ultimate brilliance.

But the fact of the mater has appeared to be that different combinations of proportions can possess equal brilliance and not surpass each other in this aspect.
