Sapphire Crystals

Sapphire crystals refer to a transparent, single-crystal form of aluminum oxide (Al2O3) known as corundum. It is one of the hardest known materials, second only to diamond on the Mohs scale of mineral hardness. Due to its exceptional hardness and scratch resistance, sapphire crystal is commonly used as a durable and protective material in various applications, particularly in optical and electronic devices.
