Blue sapphire properties

The blue sapphire, a prized gemstone, is a variety of corundum displaying an enchanting hue due to the harmonious presence of iron and titanium in its crystalline structure. This subtle combination gives each stone a unique shade, ranging from deep blue to sky blue, with intermediate variations such as royal blue or velvety blue.

When one simply mentions "sapphire," it is generally the blue sapphire that comes to mind, as its renown and brilliance have left a lasting mark on the history of jewelry and gemology. Its prestige dates back to antiquity, where it was already considered an exceptional gemstone, associated with deities and royalty.

With a hardness of 9 on the Mohs scale, the blue sapphire is one of the most durable stones after diamond, making it a preferred choice for jewelry and precious ornaments. Its crystalline structure, belonging to the trigonal system, appears in the form of hexagonal prisms that may contain natural inclusions, such as rutile needles responsible for the asterism effect observed in some star sapphires.

The color of blue sapphire is influenced by the quantity and distribution of iron and titanium within the crystal lattice. Kashmir sapphires are renowned for their deep, velvety blue hue, while those from Sri Lanka exhibit lighter shades, often described as "sky blue." Other deposits, such as those in Madagascar, Thailand, and Australia, offer sapphires in a range of tones, from dark blue to slightly violet-blue.

Optically, blue sapphire can exhibit fluorescence under ultraviolet light, though this effect varies depending on the stone’s origin and chemical composition. Some gemstones also display the phenomenon of dichroism, revealing blue-green or blue-violet reflections depending on the angle of observation.

Finally, blue sapphire is a stable and chemically resistant stone, unaffected by prolonged sun exposure or temperature variations. However, like all gemstones, it can be altered by heat treatments designed to enhance its color— a common practice in the gemstone trade.
