Diamonds of this shape have been cut and polished for many centuries, although the contemporary cut is associated with a scientist of Russian origins - Marcel Tolkowsky. Back in 1919, relying on mathematical calculations he put forward ideal geometrical parameters which reveal the optical features of a diamond to their best advantage. Since that time, the diamond has been regarded as a classical standard of a polished diamond.

Today, round brilliants are not only the most widespread cut, but also the most expensive, as in the process of cutting and polishing the irrecoverable losses are rather high, and reach more than half of the stone’s original weight. At present the bulk of round brilliants are manufactured according to a special technology so that at the output the stone could get a Triple Excellent grade- for its ideal proportions, symmetry of the facets, and polish. Not every manufacturer of polished diamonds is able to maintain such high quality, that is why products that do not conform to these criteria are called “commercial”, whereas the best, the excellent make is called “ideal” or “Smolensk”.

Owing to its ideal parameters and visual splendor, round brilliant diamonds are in high demand among customers, and are used by jewellery makers most frequently. These stones are excellent almost in any jewellery piece, be it a classical engagement ring with one or several diamonds, or earrings, a pendant or a bracelet.

Diamonds colour

The colour of a diamond is the degree of its colourlessness, the less hue possesses the stone – the better it is perceived by the viewer, the more expensive it is valued.

Polished diamonds – from colourless to yellowish or yellowish brown – are grouped into categories briefly described below. Well-trained professionals perform the colour grading procedure – by way of comparing a specific diamond to master stones.

Fancy coloured diamonds (blue, red, pink, and others) are very rarely found, and require an entirely different grading system – from Faint and Very Light to Fancy Deep and Fancy Vivid. Higher grade fancy diamonds have a greater monetary value.

At Kristall a unique and proprietary patented system of diamond grading is employed. It’s corresponding to the

Diamonds clarity

For diamonds, as well as for the majority of other natural minerals, inclusions, imperfections or blemishes are quite common. Depending on their character, location and degree of manifestation, polished diamonds are categorized by clarity grades.

In the process of the expert grading, the quantity, size and location of the inclusions and their appearance (colourless, coloured, garish, and dark), their nature (blisters, crystals, fractures) and type (dotted, diffused, large) are to be determined. The less inclusions a stone has – the more valuable it is.

However, one must bear in mind, that the presence of characteristic inclusions has one very important positive aspect: they are an unambiguous indication of the natural origin of the stone. It is no secret, that today, enormous amounts of synthetic diamonds are being grown, part of them getting but and polished, and is used in the jewellery industry. The absence of characteristic inclusions is one of the signs assuming that the diamond has an artificial origin.

Moreover, a huge number of diamond treatment techniques have been developed and are actively used: colour enhancement, inclusion elimination, and fracture filling.

Smolensk Kristall guarantees that all the polished diamonds it manufactures are neither synthetic, nor treated.
