Leo's astrological gem is the RUBY.

The red Ruby is actually a type of red sapphire. It is an extremeley hard and durable gemstone, well-suited for all types of jewelry, from necklaces and earrings to bracelets and rings. Top quality rubies are highly prized, and in larger sizes are frequently valued above other gemstones, including diamonds. Rubies over two carats are especially rare and valuable.

Just like the sign of Leo, Ruby symbolizes the sun, freedom and power. It is a sacred gem to the Buddhists, and rubies are called "tears of Buddha". When a Leo person wears a ruby, it increases their energy levels. This gem also stimulates love if worn close to the heart. If you're a Leo with a sensitive nature, wearing rubies can protect you from feeling the emotions of others too strongly. It can also calm sleep, improve circulation, and take away sadness and nightmares. In the past, the ruby was said to ward off evil spirits, protect against poisons and act as an antidote to a snakebite.

Rubies in Legend:
Rubies have been highly prized gemstones throughout history. During the Middle Ages, the ruby was believed to have an inner fire that could not be concealed. By the time of the Renaissance, only the wealthiest individuals could dream of owning a ruby. Ruby was said to be the most precious of the twelve stones God created when he created all things. In the Bible, a Ruby was placed on Aaron's neck by God's command. In the ancient language of Sanskrit, Ruby is called Ratnaraj, or king of precious stones.
