It only makes sense that many of the 'love' stones are also 'communication' stones as they help you to clearly communicate what's in your heart without becoming over emotional.
Rose Quartz: Considered the ultimate love stone. Cultivates love and invites love into your life.
Malachite: Cleans painful heartache to make way for new love.
Rhodochrosite: Love yourself first. By loving yourself you can invite other's to love you too. Release the past. It's also known to initiate playful, flirtatious energy--whisper a love's name three times into the stone and ask to be brought into your life. I love this stone in conjunction with Rhodonite.
Green Aventurine: Luck and love. Also increases confidence to attracts people to you.
Citrine: Stone of success. Help you to feel empowered, confident, joyful, and sure of self.
Hematite: Grounding. Helps to prevent emotional upset if you're feeling overly sensitive.
Rhodonite: Realistic expectations with the ones we love. Helps with healing your heart by letting go of past wrongdoings. Balances emotions when going through a hard time.
Lapis: Helps with clear communication. Brings harmony in relationships.
Apache Tear: Help to recover from grief. Holds your hand while you get back on your feet.
Amazonite: Aids in communicating true thoughts and feelings without being overly emotional. (Also good luck in gambling--which love always is!)
