Sapphires are a precious stone that is known for its deep blue color and durability. In this article, we will explore the history, properties, and uses of sapphires.


Sapphires have been treasured for thousands of years. They were first discovered in ancient Persia, where they were believed to have protective properties and were often used in talismans and amulets. The ancient Greeks and Romans also prized sapphires, and they were often used in jewelry and other adornments.

Sapphires have been mined in many parts of the world, including Sri Lanka, Myanmar, and Madagascar. The Kashmir region of India is particularly famous for producing some of the most beautiful and valuable sapphires in the world.


Sapphires are a variety of the mineral corundum, which is an aluminum oxide. Their blue color is caused by the presence of iron and titanium within the crystal structure. Sapphires can also be found in other colors, such as yellow, pink, and green, depending on the trace elements present.

Sapphires are a relatively hard stone, with a Mohs hardness rating of 9 out of 10. They are not as hard as diamonds, but they are still very durable and resistant to scratches and damage. Sapphires also have a high refractive index, which gives them a beautiful sparkle and shine.


The most common use of sapphires is in jewelry. They are often used in necklaces, earrings, and bracelets, and are particularly popular in engagement rings. Sapphires are often paired with diamonds and other gemstones, as their blue color complements many other colors well.

In addition to their use in jewelry, sapphires are also used in industry. They are used as abrasives and in cutting tools, as their hardness and durability make them ideal for these applications. They are also used in electronics, as they can be used to create sensors and other components.
