Black onyx is a stone of protection and grounding. It repels negative energy, or energies that might seek to leech off of you. Herkimer diamonds are a special variety of clear quartz that is naturally double terminated and have a very strong vibration. They often have beautiful inclusions within the stone (in this case, inclusions of carbon) giving them more character. Herkimers have a clearing and healing energy, and also amplify the energy of the other stones that they are with. These earrings help to create a forcefield around you so that you can stay safe as you do your work in the world.
