Sapphire is a precious gemstone, typically known for its stunning blue hues, though it can come in a variety of colors, including pink, yellow, green, and even colorless. The most iconic and sought-after sapphires are deep blue, often referred to as "royal blue." These stones are part of the corundum mineral family, which is also home to rubies, and they score 9 on the Mohs scale of hardness, making them incredibly durable and suitable for daily wear in jewelry.

Sapphires are prized for their brilliance and vibrant colors, which are a result of trace elements like iron and titanium. The gemstone is often transparent, but some may have natural inclusions or "silk," which can affect their appearance and value. The most famous source of sapphires is Kashmir, though they are also found in Sri Lanka, Myanmar (Burma), Thailand, and Madagascar.

In addition to their beauty, sapphires have been historically associated with wisdom, loyalty, and nobility, and they are a popular choice for engagement rings and heirloom pieces. The gemstone’s durability, vibrant color, and rich history make it one of the most beloved and timeless gemstones in the world.
