Natural Sapphire 2.10 ct – Cornflower Blue, Cushion Cut

Sapphire is a gemstone variety of the mineral corundum, valued for its durability, clarity, and wide range of colors. While blue sapphire is the most widely recognized, sapphire occurs naturally in many hues, including yellow, pink, green, purple, and colorless, with each color expressing a distinct visual character.
Chemically composed of aluminum oxide (Al₂O₃), sapphire crystallizes in the trigonal crystal system and belongs to the oxide mineral group. In gem-quality material, sapphire typically displays a vitreous luster with transparent to translucent clarity.
The refractive index of sapphire generally ranges from approximately 1.76 to 1.77, producing a restrained brilliance that emphasizes color depth rather than strong dispersion. Sapphires are found in numerous regions worldwide, with notable sources including Sri Lanka, Madagascar, Myanmar, Thailand, Australia, and parts of Africa, each associated with characteristic color and clarity profiles.

With a hardness of 9 on the Mohs scale, sapphire offers exceptional durability suitable for everyday jewelry when properly set and worn with standard care. Its high resistance to scratching and lack of cleavage make it one of the most reliable colored gemstones for regular wear.
Sapphire performs exceptionally well in rings, pendants, earrings, and bracelets, including designs intended for frequent use. While natural inclusions may be present, particularly in certain origins and colors, thoughtful setting design helps protect the stone and maintain its appearance over time.

Sapphires are commonly treated to enhance color and clarity, most often through heat treatment, a practice widely accepted within the gem trade when properly disclosed. Other treatments may exist in the market and are always evaluated and disclosed on an individual basis.
Any treatments or enhancements are always clearly stated for each individual gemstone. Every stone is professionally examined, and transparent disclosure is regarded as a fundamental part of responsible gemological practice, allowing clients to make informed and confident decisions.
