Gemstone colour is one of the five essential aspects of qualitative evaluation of a gemstone which include clarity, cut, size and enhancements as well. Undoubtedly the colour is the most significant of all the stated characteristics for it defines the lustrous beauty of any gemstone. Gemstones vary largely in their colour schemes even if they are of the same kind. It is because these are crystals made out of various elemental and mineral compositions and not every stone possess the same substance density. These minerals enrich the colour of these stones found in numerous enchanting shades ranging from transparent crystals with slight coloured reflections to deeply coloured gems. On the qualitative basis, there are three different aspects of a gemstone's colour that need to be examined for a quality judgement and colour grading of the stone.
These aspects are
A basic understanding of these three aspects assists in evaluating a gemstone's colour quality and thus, the overall appearance as the colour of the gemstone is the essence of its beauty. Nothing makes a gemstone more stunning than its very colour nurtured from the environmental conditionals and the basic chemical compositions. Here we elucidate the above mentioned aspects briefly, for basic understanding.
The top most quality gemstones have a pure colour in them complimented by secondary hues present in them which reflection in a blend with the rich original colour of the stone itself. Hue adds much to the overall reflections shades of the gemstone and differentiates all gemstones. A simple example could be that the sapphires are primarily blue stones. However, these stones are ranged from pink to purplish shades because of the hues in them. In the modern day, a variant of sapphires is known as the pink sapphire. A pink sapphire is a sapphire stone in its chemical composition but with strong pink hue, it is shaded in pink instead of the conventional blue. Usually, the description for the hue of the stone is given in the colour section of the production details.
Some gemstones are shaded in light tint while others are darker even if they are the same kind of stones. For instance, amethyst stones range from the lighter mauve like tones to the darker violet or purplish shades. These different shades are determined by the strength of the original stone colour and this strength or richness of the gemstone's primary colour is technically termed as the tone. Tone description of stones made available for jewellery embedding is written in the product descriptions of these stones.
The tone categories of gemstones are typical as follows:
Every gemstone carries secondary hues even with the purest compositions and the top most quality colour grades. It is due to the blend of mineral and elemental compositions which actually form the stone and are influenced by the environment as well. The secondary hues in brown or grey tint are referred to inclusions in gemstones. The stones with the lowest density of brown or grey hues present in them are graded the highest on saturation scale and conventionally termed as vivid or strong colour grade stones.
