What is Coral?

Coral is the skeleton of marine animals which together form reefs. Coral reefs are the largest biological structures on earth. From a natural perspective, reefs provide an important ecosystem for underwater life. From a human perspective, reefs protect coastal areas by lessening the power of waves hitting the coastline, and provide income through fishing and tourism.

Uses & Applications

On land, coral is a decorative item found in homes and beachfront establishments. It's also used in jewelry alongside actual stones or by itself in rings or beaded necklaces. In its natural state in the water, coral is a critical sea-life habitat. Major reefs become tourist draws for divers and snorkelers.

Healing Properties

Coral is often referred to as the stone of transformation. It helps one to move forward in life and accept change and progress. The positive energy force of the stone is believed to help its user release the negativity of unhealthy thoughts. It may be used to motivate and inspire positive actions and improve self-control issues.
