Its blue color is mainly caused by trace elements of iron and titanium. Blue sapphire is famous for its beauty, durability, and strong brilliance, with a Mohs hardness of 9, making it ideal for everyday wear.

Description

Blue sapphire is highly prized for its brilliance, durability, and long-lasting color stability. It is often less included than emerald but may still contain natural inclusions. High-quality stones are usually transparent with strong color consistency. Some sapphires are heat-treated to improve clarity and color, though untreated fine sapphires are more valuable.

The most famous origin is the legendary Kashmir sapphire, known for its soft velvety blue color and extreme rarity.
