The Cushion diamonds may be square with even proportions of length and width, but more often they are slightly elongated. The cushion diamond has been well-known and popular for already several centuries. Diamonds of this shape gained the widest spread in the Baroque epoch, however, in recent years, they again started to grow in popularity. They are also called “candle-light diamonds”, thus rendering tribute to those bygone times of dim candle illumination in which the brilliance of Cushion diamonds was especially dazzling.

The Cushion cut is an interesting alternative to the accustomed shapes of the Oval and “Princess cuts. By means of the diamond’s special parameters and geometry, it possesses a unique ability to retain and enlighten its colour. That is why this is the shape as a rule used for fancy colour diamonds. Owing to their rarity, diamonds of this cut may be an ideal choice for people who want to be in possession of an individual product.

Cushion-cut diamonds look perfectly in rings and earrings as self-consistent elements, however, they make a harmonious combination with polished diamonds of other cuts – for example with Round Brilliants of Pear-shapes.

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.

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.
