Montana Agate is the name given to the translucent agate found in Yellowstone River's alluvial gavels. It can be used to stimulate the crown chakra while providing grounding to the earth plane and can also enhance the meditative state. 

   Montana Agate can be used to clear and to energize all chakras and to cleanse and activate other minerals. It’s has a “sponge” like quality, which “soaks” the energies into itself. Likewise, the energies are as easily cleared away. It also has been shown to initiate the movement of the kundalini while providing grounding. Specimen measures: 40x26x3mm and weighs 7.7 grams.
