Gemstones are beautiful minerals, precious or semi-precious stones used to make jewellery. But before jewellery can be made, gemstones need to be cut and polished.
All natural gemstones are unique in their color. To understand better the terms and to be able to identify different color parameters, it is important to focus on three things when it comes to gemstones. The same type of gemstone may have different color intensities, shades, purity, saturation and tone. The main factors that determine the color of a gemstone are hue, tone and saturation.
Hue is just a primary color of the gemstone representing one of the main colors from the color palette (rainbow). Identifying the hue is as simple as stating that the gemstones are blue, red, green or yellow.
Tone determines how intense the color of the gemstone is. It can vary from light to dark; ideally, the most valuable tone would be neutral, meaning it is not too light and not too dark, but rather somewhere in the middle. Nevertheless, depending on the design and setting of the jewellery, different tones may look more appealing than others, and sometimes it is a subject of taste and personal preference.
Saturation is also referred to as the purity of color. Gemstones with excellent saturation will contain little to no brown or grey hues. Naturally, the purer the color, the more valuable the gemstone.
Gemstone’s quality is determined by one of the essential elements - cut. With years of experience in the business of jewellery and gemstones, we embrace the quality of cut to maximize the grace of each gemstone. An excellent cut will reflect on the quality of the gemstone, intensifying the color, minimizing the visible inclusions and primarily increasing the overall visual appearance. We grade cut in 4 levels: fair, good, very good and excellent.
Gemstone clarity refers to the stone’s color and clarity. The more minor inclusions it will contain, the better its grading and the more valuable the gemstone will be. The clarity of a gemstone depends on its type. The AAA clarity refers to very clean stones, while the AA clarity refers to semi clean stones. Ideally, some gemstones will be graded as AAAA quality, meaning the highest possible clarity applies. The clarity of the gemstone is always indicated in the details section of the product.
Carat refers to the measure of the gemstone. Different types of stones will possess particular densities (mass per unit amount); therefore, two gems visually looking identical in size may differ in weights. For instance, a diamond is less dense than a ruby; for this reason, a 1-carat diamond will look bigger than a 1-carat ruby.
