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