Rose Quartz Cube: Healing Crystal for Home and Office Decor, Reiki, Meditation, and Spiritual Growth A rose quartz cube is a geometric shape carved or cut from rose quartz, which is a pink-colored variety of the mineral quartz. Rose quartz is known for its gentle, soothing energy and is often associated with love, compassion, and emotional healing. It is a popular choice for making various types of gemstone carvings, including cubes. Rose quartz cubes serve as decorative items, meditation tools, and components in crystal grids. Believed to aid matters of the heart, like love and emotional healing, their metaphysical properties are subjective and lack scientific proof. Approach crystal use with an open mind and skepticism.
