star sapphires for saleRare characteristics
Synthetic star sapphire exhibits the optical phenomenon known as asterism, a star-like pattern formed on the surface of a gemstone when light interacts with parallel fibrous or needle-like inclusions within its crystal structure. Light that moves across the inclusions reflects off them, generating a narrow band of light. When two or more intersecting bands appear, a film star pattern is typically observed. star sapphires available for purchase.
Treatment star sapphires in the marketplace
The flame fusion method for producing gemstones, often referred to as the Verneuil technique, is the most cost-effective and commonly used synthesis method for star sapphire stones. Powders of chemicals (the building blocks of the gem) are deposited through a high-temperature flame. The molten powder continuously falls from the flame onto a rotating pedestal, creating a synthetic crystal known as a boule, which can later be faceted into a gemstone. Synthetic gemstones possess the same chemical, optical, and physical properties as their natural counterparts but provide a more affordable alternative to a natural gem.
