Grape Agate is a botryoidal Chalcedony coloured by clay mineral impurities, native to Indonesia.  Grape Agate is usually purple, but also occurs in shades of green and a blue green.  Beautiful to look at, Grape Agate appears as sparkly spherical clusters.

Grape Agate is associated with the third eye chakra and accordingly is a useful stone for spiritual growth and transformation, as well as intuition development.  Grape Agate is also a calming stone that in deep meditative practice can help you accept difficult situations and circumstances as they are.  

Stone carved into the human skull form is a tool that can be used with meditative practice to expand your consciousness.
