Cold Mountain Agate is sometimes also called Thunder Egg Agate; this is a beautiful and colorful stone with a lot of depth that can show nearly every color of the spectrum! These spherical geodes are found in flows of rhyolite lava. They form in the lava from the action of water percolating through the porous rock carrying silica in solution. The deposits line and fill the cavity, first with a darker matrix material, then an inner core of agate or chalcedony. They say the name thunderegg was derived from Native Americans, they believed that these were the eggs of thunderbirds said to occupy Mount Hood, and Mount Jefferson in Oregon. These stones can be found globally where conditions allow them to form. This stone is great for grounding and allowing balance in physical, emotional, and intellectual health. It helps to center and stabilize energy, by harmonizing yin and yang.
