Dragon Stone is a type of Epidote with red Piemontite grown throughout. Piemontite itself is a member of the Epidote family

Dragon Stone is a stone that activates and unlocks the heart. Piemontite has been known to strengthen and rejuvenate the heart and heal the emotional body. Its red rays pulsating off a chunk of Epidote enhances the rate at which the heart heals, and aids in a reconnection between the mind, heart, and soul. This important reconnection allows you to speak and feel as one being, and not just scattered feelings and disconnected emotions.
