Dragonstone is a unique Bastite Amygdale mineral with Green Epidote and Red Piedmontite. Piemontite is a rare, red epidote group silicate. These specimens of Dragonstone have striking red markings and patterns running through several shades of solid and orbicular patterned green Epidote. It has been named Dragonstone because of its location; Tshipise Hotsprings is below a Dragon shaped humped hill in Limpopo province of South Africa. This material has been mined, in very limited amounts, at the mouth of the old spring millions of years ago.
