The pear-shaped fancy diamond cut is a polished diamond with an outline of a teardrop or a water droplet, combining features of both the classical round brilliant, and the Marquise fancy cut. This diamond cut originates from the 16th century when diamond cuts named Rosa and Briolette were in great fashion. The latter – the Briolette cut – was the predecessor of the contemporary Pear Shape.
For Pear-Shape diamonds, different proportions of length and width are admissible. Thus, in one case the diamond may be shorter and wider, in another – prolonged with more delicate fashion. The most proportionate and harmonious elongation coefficient – i.e. correlation of the basic length and width of a diamond – lies in the range of 1.5-1.75.
Pear-Shape diamond must demonstrate ideal symmetry and distinct observance of all parameters, including the geometrical facet pattern. This is the guarantee of an equable optical reflection, especially in the tapered part of the stone, and perfectly uncovers the splendor of this gem in the best way.
Pear-Shape diamonds are very popular in contemporary jewellery art. Owing to their unique degree of symmetry, they are often used in pendants and earrings as well as in classical rings – as a central element. In this case a ring with a large solitaire drop-shaped diamond visually adds artistic gracefulness and elegance to a lady’s hand.
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.
