Crystal dont come much more super than this. Aso known as the Melody Stone or Sacred Stone.
These amazing crystals are found in only one place in the world – the Minas Gerais region of Brazil which is also called “Espirito Santo” meaning “'Holy Spirit”.  They have a very high energy and an absolutely amazing healing vibration.
Super Seven Crystals are supposed to represent the universal brother & sisterhood of humanity.  Although all of the 7 minerals it contains are not always visible (sometimes they’re just small particles), a piece of Super Seven still retains all of the properties of its combined components:
Amethyst - Clear Quartz - Smoky Quartz – Cacoxenite –Rutile - Geothite - Lepidocrocite
This is part of what makes Super Seven Crystals so powerful.  It is also one of the few crystals that retains all of the energy & healing properties of each mineral & it never needs cleaning or energizing.
