Rubies are one of the most valuable gemstones in the world. Rubies are a gemstone that comes from the mineral Corundum. Corundum is responsible for two popular gemstones, Sapphires and Rubies. Sapphires are known to include a wide variety of colors from whites to blues; however, only red Corundum gemstones are allowed the privilege of being called Rubies.
Rubies are used primarily for ornamental jewelry. The Ruby has wonderful qualities such as an incredible deep rich red color. However, it does come in a pinkish red as well. Rubies, which are made from Corundum are extremely hard and rate a 9 on the Moh’s hardness scales. They are the second hardest substance known to man, second only to the Diamond. Rubies are made from aluminum, iron and can include chromium and titanium.
Rubies are usually the perfect gemstone to create wonderful high quality jewelry out of. They are extremely strong, resistant to scratches, their color which is usually created by chromium is very stable and won’t fade and the crystal structure is extremely beautiful, shiny and transparent to translucent, making it perfect for rings, bracelets, earrings and charms.
While Rubies only are used for jewelry, Corundum has many uses being that it is extremely hard and usually a common mineral. It can be found mainly as an abrasive and you might know it as emery, as in emery boards that file down finger and toe nails. Besides being an exceptionally good abrasive, Corundum is used for several other types of industrial applications.
