Natural Blue Sapphire Cabochon

Blue sapphire is a precious gemstone that belongs to the mineral corundum, which is a crystalline form of aluminum oxide. It is one of the most sought-after and valuable gemstones in the world, valued for its stunning blue color and exceptional hardness. The only other gemstone with the same mineral composition as sapphire is ruby; the only difference is the color.

Here are some key characteristics of blue sapphire:

Color: Blue sapphires can vary in color, ranging from pale blue to deep blue, with different tones and saturations. The most prized and valuable sapphires usually exhibit a rich, velvety blue hue, known as "cornflower blue."

Hardness: Sapphire is a remarkably durable gemstone, scoring 9 on the Mohs scale of hardness. This makes it one of the hardest gemstones, second only to diamond. Due to its hardness, sapphire is an excellent choice for jewelry that is subject to everyday wear, such as engagement rings and pendants.

Origin: Sapphires can be found in various regions around the world, including Sri Lanka, Myanmar (Burma), Madagascar, Australia, Thailand, and East Africa. Each region can produce sapphires with distinct color variations and characteristics.

Uses: Blue sapphires are most commonly used in jewelry, such as rings, necklaces, earrings, and bracelets. Their beauty and durability make them a popular choice for engagement rings and other special occasion pieces.

It's important to note that, like any gemstone, the value and quality of a blue sapphire depend on factors like color, clarity, cut, carat weight, and origin. A certified gemologist or reputable jeweler can help you assess the quality of a blue sapphire if you're considering purchasing one.
