These natural Madagascar clear quartz crystals are most amazing. They have heavy coatings of creamy white limonite or red/orange hematite, but are extremely clear inside. These crystals can also be included with many other minerals. Almost all of these crystals have some natural runs and dings. Finding one in perfect condition is next to impossible. While these crystals are not as bright and shiny as Arkansas quartz crystals they vibrate at a higher frequency and are preferred by most healers.
