The range of colors of Star Sapphires varies considerably from blue to white. We will favor samples containing little or no inclusions on the surface, stones of great clarity, transparency, weight, dimensions, color of the stone, provenance. Quality and criteria of choice of star sapphires The most sought after and coveted Star Sapphires are those whose optical effect (asterism) is the most perfect, namely a complete star, well centered, thin, with branches that extend over the entire front of the cabochon. In order for the asterism to be visible on Sapphire samples containing Rutile needles, the lapidary must cut the cabochon gem so that its base is parallel to the Rutile inclusions. The occurrence of this star with 6 branches is due to the reflection of a light ray on the inclusions of Sapphire (Rutile needles). The stone when shaped as a cabochon (dome) presents when exposed in daylight and direct rays of the sun: a star on its surface. Star Sapphire is a variety of Sapphire that is characterized by the presence of the optical phenomenon called asterism.Ī variety of corundum exclusively intended to be shaped in cabochon The etymology of Corindon comes from the Sanskrit 'Kuruvindam', while the name 'Saphir' comes from the Persian word 'Safir'.

Sapphire is a variety of Corundum that exists in almost all colors, and in addition, in two-colored and multicolored. Is it pure coincidence that its level of hardness (9 on the Mohs scale) makes Sapphire one of the most enduring jewels of all time? Or, is it related to the blue color usually symbolizing the masculine color par excellence?Ī sapphire please, but not any sapphire, a sapphire with a star, otherwise nothing !
