The gemstone known as the "King of Gems" is the sapphire. Esteemed for its stunning blue color, particularly in its classical form, the sapphire symbolizes nobility, truth, and wisdom. It belongs to the corundum family, with rubies being its only other color variant. Sapphires have captivated people for centuries, adorned in crowns and religious artifacts due to their perceived protective qualities. Their durability (rated 9 on the Mohs scale) makes them ideal for everyday wear, increasing their popularity in engagement rings and jewelry. Beyond blue, sapphires can also be found in a variety of colors, making them versatile and desirable.
