Cut is one of the five most important characteristics of a gemstone. It is impactful on the gem's quality. A gemstone's true beauty lies in its beauty and the cut enhances the colour reflection of the stone adding to its appearance. Gemstones in raw crystal forms are not as stunning as those you see embedded in various jewels and other embellishments. These stones are cut well by the artisans to bring out the quality in their dazzle making them the real worth they are.
Gemstones are found in a variety of colours and each differs from the other in its natural composition which matters much to the hue and saturation and so there are no defined geometric symmetries or cuts set as standards for the gemstones, it is all the artistry of the craftsman to cut a stone well enough to bring out its real shine.
Colour is what is significant to a gemstone’s enchantment and so a stone is cut to enhance its colour grade on apparent attraction to the eye. A good cut enhances the colour reflection of the stone and simultaneously covers the inclusions, imperfections in the stone. As elaborated above there are no standardised structural shapes that are set to define a good gemstone cut. Gemstones are crystals with various elemental compositions which lend the hue and saturation to the stone. Since a gemstone’s colour is the most significant aspect of qualitative evaluations the cut is determined for each stone by the expertise of the craftsman. Commonly a deeper gemstone cut is preferred for stones with high colour saturation grade while a shallower cut is preferred for the ones with lesser colour saturation. Saturation is important since it refers to the presence of brown or grey tints as the secondary hues in any stone. A high saturation grade is inversely proportional to the amount of these hues present in a stone. A shallow gemstone cut allows more light to enter the gemstone than a deeper cut.
Some gemstones are exceptional to the case of colour enhancements in which the cuts are not made for colour refinements but to increase the stone’s size dimensions and carat weight. Ruby is one prime example of such stones. It is a precious gemstone known well for the richness of its colour and the thickness of saturation. Rubies are usually cut to maximise their size values instead of highlighting the colour of the stone.
Even though there are no standardised geometrical standards for gemstone cutting but the symmetry is very significant. A good cut is a symmetrical cut. A gemstone with a symmetrical cut has a higher quality grade than a case otherwise. Basically, colour saturation and hue evenness are vital to a gemstone's beauty and so the stone must reflect the light penetrating into it with uniformity as well. An asymmetrical cut tends to deteriorate evenness of light reflection, by basic laws of physics, and so for better light reflection and more refined appearance of a gemstone a good cut is always symmetrical. Also, a more symmetrically cut gemstone has a better and more even surface polish minimising the probabilities of chipping and surface blemishes and thus, ensuring a high-quality grade for a gemstone.
