A couple of good ones and a bit about them. (If you want to know healing properties just ask they are long and you are just looking for the ones on love.)
Rose Quartz- love stone - chakra is the heart - aids development of forgiveness, compassion, and love.
Amethyst- Divine Love, healing, inspiration, and intuition - chakra is the third eye and crown.
Aquamarine- excellent for meditation - Inspiration, peace, calmness, and love - chakra is the throat and solar plexus.
Emerald- strong emotional balancer- Prosperity, love, kindness, tranquility, balance, healing, and patience- chakra is the heart and solar plexus.
Garnet- enhances imagination - love and compassion - chakra is the heart and root.
Jade- radiates divine, unconditional love - clarity, modesty, courage, justice, and wisdom - healing will correspond to the color of the jade.
Rhodochirosite- Red/Pink color helps to blend courage/will/passion aspects of lower chakras with loving expression of the heart- divine love, acceptance of self and life-powerful healer for those attuned to this stone- chakra is the root and heart.
Hope this helps, Blessed Be
