The Emerald cut is a step-like orthogonal form with truncated corners. The Emerald is commonly used by jewellers and is regarded as a rather popular classical fancy cut.
This cut is applied to larger rough diamonds, with the best characteristics of colour and clarity as owing to large, open facets it is practically impossible to hide even the smallest inclusions.
The Emerald-cut diamond possesses unique optical properties. Although to some extent it gives way to the Round Brilliant or Princess cuts in light refraction and sparkle, thanks to its shape this diamond leaves them behind as far as the power and brilliance of the returned light flux are concerned. All the light falling onto the stone is reflected back – in wide and bright flashes.
The exquisite and elegant shape of the Emerald-cut diamond is always a symbol of superior taste, wealth and high social status. This is precisely why jewellery pieces with these diamonds are regarded chosen not only by delicate ladies but also by successful men of all ages.
Emerald-cut diamonds are frequently encountered in large class rings, which emphasize the size and clarity of these stones. They are also often encrusted into rings and earrings, in many cases in combination with other diamond shapes.
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.
