This is a beautiful Blue Sapphire Boulder with Golden, White, and Black Mica compliments. The Blue Sapphire is a lovely sky blue. There are books of Golden and White Mica and veins of Black Mica, and several green patches of what looks to be Peridot. The whole boulder sparkles in the light. I’m not sure what the matrix rock is … possibly Quartzite (a metamorphic rock composed of quartz that has been metamorphosed by the same processes that created the sapphire). Sapphire is associated with the Third Eye Chakra and enhances creative expression and intuition.
