One fascinating fact about blue sapphire is its remarkable hardness. Blue sapphire belongs to the corundum mineral family, which is one of the hardest mineral families on Earth, ranking 9 on the Mohs scale of mineral hardness. This exceptional hardness makes blue sapphire highly resistant to scratching and abrasion, making it an ideal gemstone for everyday wear in jewelry pieces such as rings, bracelets, and necklaces. In addition to its durability, the hardness of blue sapphire contributes to its enduring beauty and longevity, allowing it to retain its luster and brilliance for generations.
