It is characterized by its vibrant and diverse colors such as red, pink, white, and orange, which give it a distinctive presence among natural gemstones. It is often smooth to the touch with a waxy luster after polishing. Its valuable types are extracted from warm seas, especially the Mediterranean Sea and the Pacific Ocean. The rarity of some colors, especially deep red, has made coral a distinguished organic stone in the world of gemstones.
