Perfectly clear quartz catches light and sparkles in the sun. This clear crystal is often called a “master healer" because it's believed to help amplify the energy of any other stones and whatever energy is in the immediate environment. Carrying a hand-carved miniature phallus in your pocket is sure to bring a strong boost of energy! Clear quartz is popular for meditation, concentration, and enhancing memory and is a go-to stone for nurturing growth.
