Gems: A Lively Guide for the Casual Collector
“The ruby is the traditional birthstone for July, though others consider it a birthstone for December. It is used to celebrate a couple’s fifteenth and fortieth anniversaries. The ruby is considered the most powerful gem in the universe, and as such is associated with a variety of astral signs, including Cancer, Leo, Virgo, Scorpio, and Capricorn. It is often associated with the sun, though some link the ruby to the planet Mars… the star ruby is regarded by some astrologers as a stone of the sun… In ancient times, wise men were thought to carry star rubies with them wherever they traveled, as they believed the star to be the source of great wisdom. The six-pointed star is said to represent the virtues of faith, hope, and charity,”
