The corundum family of gemstones consists of ruby and sapphire. Corundum is very compact, dense, and lacks gemstone cleavage. It’s also the second hardest natural mineral after diamond. Gem-quality corundum is also quite rare. These factors make both varieties of corundum some of the most highly desired jewelry stones. Ruby is the red variety of corundum. All other colors of corundum, including colorless, are called sapphires.
Rubies and sapphires are some of the most valuable and popular of all gemstones. Despite the enormous size of these stones in museums and royal collections, most corundum gems available for sale are usually of more modest size. A 3-4 carat ruby of fine quality would be a rare and very expensive gem in today’s market. Sapphires over 5 carats, clean and with good blue color, are similarly rare and also valuable. Relatively speaking, there is an abundance of good quality small sapphires but not rubies. Very few known ruby deposits can be actively worked, while there are many more sapphire deposits being actively mined.
