What Are the Uses for the Gemstone Ruby?

Rubies are red gemstones formed from corundum, which is made up of aluminum, iron, and small bits of chromium and titanium. Sapphires are also formed from corundum and come in a variety of colors and sizes. Only red sapphires are referred to as rubies, however, which gives them a unique classification all their own. Rubies are also extremely hard, in second place behind diamonds as the hardest gemstone that occurs in nature.

The first and most popular use for rubies is as decoration, in rings, earrings, bracelets, and necklaces. Because of their rarity, value, and color, rubies are often prominently displayed in the crown jewels of royalty. Even artificial rubies, which are formed in a laboratory, are often in demand due to the association of the stone with wealth.

Some of the first laser technology used artificial ruby crystals as the focusing source for the light. This is still the case, though many other gems, including the ruby's cousin sapphire, are now used to focus lasers. The use of rubies is likely the reason that lasers are associated with the color red in popular media and fiction.

Rubies, according to many new age schools of thought, can be used for a variety of healing purposes as well as for personal protection. Rubies supposedly make it easier for people to reflect on their thoughts and actions. Rubies also help people achieve their desires, and to move forward with plans. Rubies shield the wearer from negative energy and can help in negotiations. They are also considered to bring good luck.

Though not as popular a use in the modern era, rubies were at one time accepted almost as freely as currency. This was especially true in Asia, where the ruby was a mark of status and nobility. Scabbards, saddles, armor, and other symbols of rank in India, China, and other countries in Asia are often found to bear rubies for decoration, and early records show that rubies were brought along the Silk Road from the East to the West for use in trade.
