Personally I love the energy of the rose quartz crystal. It feels very different to the other crystals when working with it internally. Very soothing, gentle and caring.  A nice way to start connecting your Yoni and heart energies. This stone is often called the Love Stone as it communicates with the Heart chakra. When you are ready to dissolve your emotional blocks, when you want to give and receive the energy of love to yourself and others, this is a beautiful stone to use.
