The Princess-cut diamond is a diamond of a square (more rarely – of an orthogonal) shape with pointed angles. The Princess-cut is deemed to be of a higher-level technological stage of the development of older cut-shapes that existed in the previous century. Today, it is by all means the second the second diamond by popularity after the Round Brilliant.
By form, the Princess-cut diamond resembles a pyramid and ideally fits into a rough diamond of a regular octahedral form. Owing to this, the loss of the initial weight of the stone in the process of manufacturing is very low, and this favourably manifests itself in the diamond’s price: with comparable weight, the Princess diamond will cost substantially less than a Round Brilliant.
However, such difference in price does not mean that the brilliance of a Princess diamond is less appealing. The majority of the existing fancy cuts cannot compare with a Round Brilliant in their shine and luster. The Princess, however, specially developed in such a way, so that to maximally approach the round cut in this respect. Unlike the round cut, the bulk of the weight of a Princess-cut diamond is concentrated in the pavilion, the lower part of the diamond. That is why the brilliance of the stone comes out of the depth of the diamond creating a dazzling attractive effect. Besides, all these iridescent flashes of light and magical glimmering become more expressive and inimitable together with the increase if the weight and dimensions of the stone.
Due to their regular geometry, the Princess-cut diamonds are widely and willingly. Engagement and wedding rings, either with a single stone, or with several diamonds, along with the so-called tennis bracelets, are the most widespread jewellery pieces with Princess-cut diamonds
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
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.
