This can be any crystal cut into a traditional heart shape. Crystal hearts represent love (no surprises there) and connect with the energy of our heart chakra. A heart crystal can be placed over this chakra in healing work. Focus your energy and attention on your heart and imagine it filling with pure loving light.
Crystal hearts are powerful allies in helping to attract love from others, as well as nourishing yourself with love from within.
In crystal form they help “bring down” the celestial energies to us when we do healing and energy work. “As above, so below” is a good phrase to describe stones cut into stars.
