Diamonds of an oval cut are a distinctive example of the so-called brilliant cut and they got their name thanks to their specific ideally oval outline. This diamond cut appeared not so long ago – at the beginning of the 60-s – and since that time, has won wide popularity among the connoisseur of gemstones of unusual (or fancy) shapes. In the making of this diamond cut, they use the same principles as in the making of a round brilliant, usually with the same number of facets possessing similar geometrical form.
The Oval cut diamonds have excellent characteristics of fire and luster, close to those of the round brilliant. However, with an absolutely the same weight, the Oval visually looks more advantageously that the round brilliant – owing to its elongated form and a bigger table – creating an illusion of bigger dimensions. In addition, Oval-cut diamonds cost less than similar round diamonds as this illusion helps to substantially save the budget of their buyers.
The Oval cut has firmly established itself in the jewellery world. Owing to their good symmetry, the Oval-cut diamonds may be used in various jewellery pieces of different styles. In the best way possible they are appropriate as single stones in rings, earrings, pendants, they also look harmoniously when surrounded by smaller diamonds. In a ring, the Oval diamond visually makes the fingers look longer – more delicate and graceful.
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.
