The knot, the link.

A piece of jewelry given to someone who is important to you. This piece of jewelry illustrates that strong, inseparable bond. A bond of the heart, a bond of blood, a bond of friendship. What is a coral knot? It's created by marine life: a fish might swim too fast past a coral branch and break it. The branch continues to grow with the help of its neighbor, hence this closed and unique shape.

A powerful image that will express your love or friendship to someone who matters to you.
