The knot, the bond.
A piece of jewelry to give to someone who is important to you.
This piece of jewelry illustrates this strong, inseparable bond. A bond of the heart, a bond of blood, a bond of friendship.

What is a coral knot? This closed shape forms naturally underwater. It's marine life that does it: a fish might swim too fast past a coral branch and break it. That same branch continues to grow with the help of its neighbor, hence this unique closed shape.
A perfect image to express your love or friendship for someone who is important to you!
