Communication
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!)
