High Jewelry Sapphire Jewelry

By default, the color blue is associated with sapphire, and the most sought-after shade is a true cornflower blue. However, the gem can be of all colors (except ruby red) or even colorless for leucosapphires.
Like all gemstones, the sapphire has inclusions of different natures: minerals, channels, or even liquid inclusions.
However, far from being imperfections that would devalue the stone, as is the case with diamonds, these inclusions guarantee its authenticity and natural origin since synthetic sapphires do not have them. The nature of the inclusions also allows for determining the type of deposit from which the sapphire was extracted.
Naturally, too large or too numerous inclusions affect the color and appearance of the sapphire, which generally depreciates the value of the gem, except for rutile inclusions that enhance it. Indeed, rutile needle inclusions give the sapphire, like rubies, soft reflections called "silks." Depending on their orientation within the stone, these inclusions produce either a chatoyancy, that is, a luminous phenomenon reminiscent of the slit pupil of a cat's eye (the sapphire is then called "cat's eye"), or an asterism, that is, a luminous phenomenon that forms a star or a cross on the surface of the stone (the sapphire is then called "starred").
