Rubies are one of the most sought after gemstones in the world. Rubies are made from Corundum, one of the hardest stones known to man and second in hardness only to diamonds. It should be noted that the mineral corundum creates two distinct gemstones, the Ruby and Sapphire. Sapphires come in a variety of beautiful colors, however only the red Corundum is considered a Ruby. Rubies can vary in color from a pinkish orange color to a deep red color. Since natural occurring rubies are very rare and extremely rare in large sizes over 3 carats, they can demand prices higher than diamonds.


Rubies are perhaps one of the oldest known gemstones to man. They have been revered since the beginning of time and possessed for their beautiful qualities. In sanskrit, ruby is ratnaraj, meaning the king of gems. Ruby retained its importance with the birth of the western world and became one of the most sought-after gems of European royalty and the upper classes. Many medieval Europeans wore rubies to guarantee health, wealth, wisdom, and success in love.

Today, desire for ruby is just as great as it always has been. As a symbol of passion, the ruby makes an ideal romantic gift. Consumers are drawn to the lush color because it also signifies success and wealth.
