Happy Birthday July Babies!!! Like a perfect Red Rose, Ruby's rich color denotes Love and Passion. Ruby is the birthstone for July and is considered the king of all gems.  In ancient times, it was believed that wearing a Ruby bestowed good fortune upon the wearer.  The gem has been prized by kings and emperors throughout the ages.  The color of the stone is its most important feature.  The stone comes in hues varying from purplish to bluish-red or orange-red.  The red Ruby is the brightest and most well-known and considered the most valuable.  So, July babes go out and like your birthstone display your bright vivacious personality.
