September Birthstone: The Timeless Sapphire
Few gemstones carry the prestige, beauty, and history of the sapphire. As September’s birthstone, the sapphire has long been cherished as a symbol of wisdom, loyalty, and nobility. With its deep blue hues and exceptional durability, the sapphire continues to be one of the most sought-after gemstones in fine jewelry today.
In this blog, we’ll explore everything you need to know about sapphires, from how they form in the earth, where they are found, and their unique properties, to their history, symbolism, and modern appeal.
How Sapphires Form
Sapphires are a variety of the mineral corundum, composed primarily of aluminum oxide. When trace elements like iron and titanium are present, they create the stone’s rich blue color. Corundum crystals form deep within the earth’s crust under high pressure and heat, often in metamorphic rocks such as schist and gneiss, or in alluvial deposits where weathering has carried them downstream over thousands of years.
Interestingly, sapphires can be found in a range of colors, pink, yellow, green, purple, and even colorless, but the rich royal blue sapphire remains the most iconic. The only color corundum cannot be is red; those gems are classified as rubies.
Sources of Sapphires
Sapphires are mined in several parts of the world, each region producing stones with distinct characteristics:
Sapphires are cut into a variety of shapes, from classic rounds and ovals to fancy cuts like cushions and emeralds. The way a sapphire is cut greatly influences its brilliance, as the cutter must carefully balance depth, color zoning, and clarity.
On the Mohs scale of hardness, sapphires rank 9 out of 10, second only to diamonds. This makes them exceptionally durable and ideal for everyday wear, whether in rings, pendants, or earrings.
Healing and Symbolic Properties
Throughout history, sapphires have been associated with powerful healing and symbolic qualities:
The sapphire’s history is as rich as its color. Ancient Persians believed the earth rested on a giant sapphire, and its reflection made the sky blue. In medieval Europe, sapphires symbolized heaven, and clergy wore them to represent purity and wisdom.
Royalty has long favored sapphires as well. One of the most famous examples is Princess Diana’s sapphire engagement ring, now worn by Catherine, Princess of Wales. This iconic piece cemented sapphires as a timeless symbol of love and devotion.
