Sapphire is a precious gemstone, most commonly blue in color, though it can come in a variety of hues, including pink, yellow, green, and even colorless. It is a variety of the mineral corundum, with the blue color primarily resulting from trace amounts of iron and titanium. Known for its durability, sapphire ranks 9 on the Mohs scale of hardness, making it one of the hardest natural gemstones, second only to diamond.
Sapphires are often used in fine jewelry, including rings, necklaces, and earrings, and are popular choices for engagement rings due to their strength and beauty. The most prized sapphires are typically a deep, vivid blue, but the stone’s rarity and value can vary depending on its color, clarity, and size. The gem has also been historically associated with wisdom, nobility, and divine favor, and it is often worn as a symbol of loyalty and sincerity.
In addition to its use in jewelry, sapphire has industrial applications as well, including in high-durability windows, watches, and even electronic devices.
