A proper execution and close examination of each gemstone is done by the specialists to verify an even color with minimal color zoning or spotting. An even color and crystal clear appearance is the most esteemed feature in a sapphire. These unique attributes affects the overall beauty of the stone. These rarities make sapphire more attractive and elegant. The color of sapphire is evaluated on three different characters: tone, hue, and saturation.
‘Tone’ is the word used to illustrate the depth of the color present in the gemstone. For instance, to compare a sky blue sapphire to a midnight blue sapphire, it would be appropriate to say that they are same but the tone is dissimilar. The hue or color of the midnight blue sapphire has dark tone whereas the sky blue sapphire has light tone. There are different varieties of sapphires available in the market, and the range of tone is available from light to dark. The standard blue sapphires are present in the medium deep blue range.
Machining sapphire process is difficult for the stones having higher saturation values. Sapphires with the highest levels of saturation display the crystal clear and true colors. These are also known to have a vivid saturation.
