What Is a Sapphire?
A sapphire is a precious gemstone from the corundum family, best known for its deep blue color. While blue is the most recognized shade, sapphires naturally occur in a wide range of colors, including pink, yellow, green, and purple—commonly referred to as “fancy sapphires.”
In gemology, all corundum gemstones are classified as sapphires, except for red varieties, which are known as rubies.
How Are Sapphires Formed?
Sapphires are formed deep within the Earth under extreme heat and pressure. Trace elements such as iron and titanium are responsible for the blue coloration commonly associated with sapphires.
Due to their crystalline structure, sapphires are exceptionally hard and durable, making them one of the most practical gemstones for fine jewelry and daily wear.
Natural Sapphires vs Other Blue Gemstones
Although many gemstones appear blue, sapphires are distinguished by their superior hardness, color stability, and long-term durability.
