Quartz crystal/agate cylinder / There are two main groups of quartz: chert and chalcedony. Agates form in cavities left by gas bubbles in cooling lava. Silica-rich groundwater builds layers of crystals on the cavity walls.
One of my favorite stones.Malachite is a stone of transformation that works to clear and cleanse your chakras. It is a powerful heart chakra crystal that helps to open your heart to all types of love. It also protects you from negative energy.
