Rose Quartz is a gentle loving stone that helps with forgiveness, alleviating grief, and increasing empathy. It’s a go-to for increasing self-esteem and love while gently facilitating a beautiful journey of self-esteem and worth. 
The chakra stones are for rebalancing the chakras. They help you to release negativity which results in emotional release - moving those energies through and out of your body so that you don’t hold onto and store them which would result in poor health.
