Sapphire is a precious gemstone known for its stunning brilliance, exceptional hardness (second only to diamond), and vibrant colors most famously deep blue. Composed of the mineral corundum, sapphire is highly valued in jewelry and also prized for its industrial applications, including scratch resistant glass, high-durability watch faces, and infrared optics. Its rarity, durability, and aesthetic appeal make sapphire both a luxury asset and a high-tech material of strategic importance.
