Aquamarine
This crystal is renowned for helping you sift through energy and information, create mental clarity, and soothe an overactive mind; it's even used to improve the intellect. It evokes the crystal blue purity of water and the peace and calm that the sea can bring to our soul. In ancient times, aquamarine was believed to be the treasure of mermaids. As the first of the Spring birthstones, this crystal represents transformation and rebirth.
