1. What is coral?
Coral is a marine organism that forms colonies of calcareous skeletons. The corals used in jewelry are fossilized or hard remains of these skeletons, extracted primarily from the Mediterranean, Pacific, and Indian Oceans.

• Red coral (Corallium rubrum): Highly prized for its deep red or orange-red color. Traditional to the Mediterranean.
• White coral: Creamy or pure white. Rarer and more delicate.
• Bamboo coral: With natural bands reminiscent of bamboo, widely used in Asian crafts.
• Black coral: Dark tones, less common, valued for its rarity.
3. Physical properties
• Composed mainly of calcium carbonate.
• Light and relatively soft (hardness 3-4 on the Mohs scale).
• Porous, sensitive to acids and heat.
4. Energy properties and traditional uses
