A rare, trendy and so chic gemstone

The blue star sapphire is a stone that we see more and more set in jewelery and especially for jewelry for men. 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?

A sapphire please, but not any sapphire, a sapphire with a star, otherwise nothing !

Sapphire is a variety of Corundum that exists in almost all colors, and in addition, in two-colored and multicolored. Red Corundum is known as Ruby. The etymology of Corindon comes from the Sanskrit "Kuruvindam", while the name "Saphir" comes from the Persian word "Safir". Star Sapphire is a variety of Sapphire that is characterized by the presence of the optical phenomenon called asterism.

A variety of corundum exclusively intended to be shaped in cabochon

The stone when shaped as a cabochon (dome) presents when exposed in daylight and direct rays of the sun: a star on its surface. The occurrence of this star with 6 branches is due to the reflection of a light ray on the inclusions of Sapphire (Rutile needles). 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 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.

Provenances, availability, price and valuation of the Star Sapphire

Currently, the most productive deposits are in Ceylon and Madagascar. It is estimated that the occurrence of star sapphire samples is between 1 and 2% of Sapphires extracted from a deposit producing star sapphires. In addition to this tiny percentage, we must know that we can find a sample capable of producing a perfect star but which will have an unsightly color and conversely a beautiful color of stone, but a no star, incomplete or very little visible. These are the reasons for the rarity of genuine natural star sapphires on the market.
