The shape named “Marquise” is an elegant diamond of a prolonged shuttle-like form tapering off at the ends and visually resembling a small boat. There is a legend according to which the stone got its name in honour of the beaming smile of the favourite of Louis XIV – Marquise de Pompadour. Presented to the public several centuries ago, this diamond today is regarded as classical and indeed a true royal diamond.
Marquise-cut diamonds are often made of prolonged diamond crystals, as this allows saving the weight and size of the natural mineral to the maximum. As a result, we have an elegant polished diamond visually perceived bigger than it is in reality: the Marquise cut allows to magnify the stone visually thus creating an illusion of a bigger diamond.
Marquise-cut diamonds are not as expensive as the traditional round brilliants, the loss of the original weight of the latter being much higher. However, it does not mean that the brilliance of the Marquise diamond is less appealing. Owing to the accurate arrangement of its symmetrical facets, by form resembling an elongated round brilliant, the Marquise cut possesses excellent shine and dazzling luster.
The Marquise cut tellingly appears in a diamond ring both as a single solitaire stone as well as surrounded by smaller diamonds of a round and pear-shaped forms smoothing out its tapered corners. The elongated form of the Marquise diamond confers an effect of thin and elegant fingers to the hand of its owner.
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.
