Rubies: July’s Birthstone


Rubies and sapphires are two of the most famous and coveted gemstones in the world. But did you know that they are actually different varieties of the same mineral? Both rubies and sapphires belong to the corundum family of minerals. Corundum is composed of aluminum and oxygen and is colorless in its most pure state. But when other trace elements are present, they produce colors. If titanium and iron are present, they create a deep violet blue color and the stone is a blue sapphire. If that element is chromium, it creates a red color and the stone is called a ruby.

Rubies occur in a range of colors, from dark, brownish red to a vivid, bright, true red (often referred to as “pigeon’s blood”) that is the most sought after and valuable. A large number of stones of this excellent quality have historically come from Myanmar’s Mogok mines, but rubies are also mined in large quantities in other locations including Thailand and Sri Lanka.

Its not only the beauty of rubies that makes them ideal for use in jewelry. Both sapphires and rubies are very “hard” gemstones – they are a 9 on the Mohs hardness scale. The Mohs scale measures one gem’s ability to resist being scratched by another. A diamond is the hardest at 10, therefore diamonds can scratch all other gemstones, but rubies come in at a close second. This makes them ideal for daily wear, particularly in rings, because they are less likely to become damaged.
