How to Identify Genuine Coral: Spot Real Coral from Imitations Easily
Coral jewelry has captivated admirers for centuries with its vibrant hues and organic charm.
In short: Genuine precious coral (Corallium rubrum) is calcium carbonate from Mediterranean reefs, Mohs 3-4 hardness, with a fine wood-grain pattern visible under magnification and a distinctive pinkish-red color. It reacts to dilute acid by fizzing; plastic and dyed-bone imitations do not. Fine 1.00ct+ Sardinian beads run $50-$300 per carat. CITES paperwork is required for cross-border sales.
However, with the market awash with imitations, distinguishing genuine coral from fakes is more crucial than ever.
Whether you're a collector, jeweler, or simply someone enchanted by coral's beauty, understanding how to identify authentic pieces is essential.

Let's look at the world of coral and uncover the secrets to spotting the real deal.
Understanding Genuine Coral
Genuine coral is the skeletal remains of marine polyps, tiny sea creatures that form colonies in warm ocean waters.
Over time, their accumulated skeletons create the coral structures we admire.
The most sought-after varieties in jewelry include:
- Precious Red Coral (Corallium rubrum): Renowned for its deep red to pink hues, this coral is primarily found in the Mediterranean Sea and has been a jewelry staple for centuries.
- Bamboo Coral: Typically white or pale in its natural state, bamboo coral is often dyed to achieve vibrant colors, making it a popular choice in various jewelry pieces.
- Black Coral (Antipatharia): Valued for its dark, rich tones, black coral is rarer and often used in unique, high-end jewelry designs.
