A pearl is referred to as the queen of the sea and in many cultures symbolizes a long life. Wearing a pearl is supposed to bring calm, peace and connection. It is therefore not surprising that a friendship or marriage of 30 years is referred to as a Pearl Anniversary. These earrings are therefore the ultimate gift for someone you have been friends with for 30 years or someone with whom you would like to be friends with for at least 30 more years. The Neptune hoops are available in a gold plated and a silver plated version.
