Assher Cut is a variation of the Emerald Cut – ideally square in form, with exact geometry of the cut angles. This king of cut was invented back in 1902, by a known artisan in the diamond industry Joseph Assher from Amsterdam.
The style of the Assher Cut combines traditional charm and state-of-the art technologies, together providing its dazzling brilliance. Providing expert calculations and accurate manufacture, the Assher Cut diamond is characterized by an excellent yield and minimal losses of the original rough diamond. Large and open facets are distinctive features of this cut. Thus, on the one hand, similar to the classical Emerald, the Assher Cut diamond is picky to its clarity grade as the most insignificant inclusions will be easily spotted. On the other hand, its facets give the diamond a solid and dignified appearance.
Jewellery with Assher Cut diamonds make their owners look respectable and even aristocratic. The peak of popularity of these diamonds fell on the 30-s, although these days they are returning back, gaining even more attractiveness, especially among men. Assher Cut diamonds are most commonly used in class rings and handcuffs. Nonetheless, owing Assher Cut diamonds are very successful with ladies – in most elegant necklaces and bracelets, as well as in high-fashion rings.
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.
