http://gia.edu/gem-encyclopedia What Attracts Us to Ruby: Properties by GIA. What are ruby gems, and how to use ruby gems? In this video, Edward Boehm explains how the unique properties of ruby, such as its famous red ruby color, create a strong desire and attraction for this gem. Ruby is the most valuable variety of the corundum mineral species, which also includes sapphire. Traces of chromium give this red variety of the mineral corundum its rich color. For better-quality material, slight differences in color can make significant differences in value. Rubies can command the highest prices of any colored gemstone. The per-carat prices of fine-quality ruby gems have been rising consistently, many times breaking auction records.
