Sandstone is composed of sand sized Quartz or Feldspar minerals. Sandstone comes in many colors, but is mostly found in brown, yellow, red, gray, pink, white and black. Sandstone builds up in layers and creates beautiful landscape-like patterns when polished into healing crystals. In crystal healing, Sandstone is used for grounding with our current reality. It is also used to strengthen our emotional center, promoting love and acceptance.
