Just for fun, this is what I found on the internet-

The ruby is considered to be the most powerful gem in the universe, and is associated with many astral signs. To own a ruby is said to have contentment and peace. Placed under a pillow the ruby may ward off bad dreams. Ruby rings should be worn on the left hand so as to receive the life force and have protection. Given as a gift, the ruby is a symbol of friendship and love. The ruby is also the symbol of vitality and royalty.

 

Love stone

The Ruby is filled with love. It also helps sexual love to be more passionate. Persons lacking in self-love should have and mediate on the Ruby. It also gives the courage to be best potential that a person has.
