Dark and mysterious, Scorpio sun signs are intense, powerful and deep. Oftentimes tuned inwards, they can become secretive, complicated, jealous and anti-social. They are very good at keeping their emotions hidden, and have trouble letting things go. They are also passionate, creative and driven to succeed at everything they, and they strive to do it right the first time.
Amethyst is very useful for a Scorpio because it has the power to calm the mind - which sometimes a Scorpio can get stuck in. It can rid toxic thought patterns.
Aquamarine helps Scorpios communicate their true feelings.
Labradorite can clear the mind, so Scorpios can enjoy their creative side.
