Moonstones sooth stress and promote flexibility. Though you can get exciting things like chocolate or mint moonstones, my favourite is the milky, almost iridescent moonstone. Lapis Lazuli brings success in relationships. Obsidian and Apache Tears ease and release both pain and anger. They also can be used for protection.
Opals help to clarify and amplify.
But, this is a fragile stone. Do not immerse in water. They cool and soothe. Peridot promises married happiness. Pyrite promotes memories of love and friendship.
