Black Coral in Cozumel

If you've visited Cozumel, chances are you've walked past gift shops proudly displaying jewelry, bracelets, and decorative carvings labeled as "black coral." Vendors might eagerly assure you of their authenticity, promoting these souvenirs as rare treasures from the sea. But beneath the sales pitch lies a troubling reality—genuine black coral is endangered, strictly regulated, and often illegally collected. Before considering any purchase of black coral products, you should be informed about the ecological significance of these corals, the regulations protecting them, and how you can help preserve Cozumel's fragile marine ecosystems.

What is Black Coral?

Black corals (Order: Antipatharia) are deep-sea, tree-like animals—not stones, plants, or algae. Despite their name, living black coral colonies can appear white, red, yellow, or green, while only the skeleton is truly dark in color. Black corals can be found across all oceans, with several species making their homes in the waters surrounding Cozumel. Unlike reef-building corals, black coral does not rely on sunlight or symbiotic algae, allowing it to thrive in deeper waters with little light. Despite its name, living black coral is not black. Instead, it is covered in a layer of living tissue that can be white, yellow, or orange. Its inner skeleton, which is dark and rigid, is what gives black coral its distinctive name and makes it highly prized for jewelry and decorative items. However, due to its extremely slow growth—only 8–22 micrometers per year—it is highly vulnerable to overharvesting and environmental threats.

Is Black Coral Rare?

Yes. In Cozumel, black coral has become extremely rare due to overharvesting. Species like Plumapathes pennacea and Antipathes caribbeana once thrived along Cozumel’s deep slopes, but population surveys show dramatic declines​. Juvenile colonies are scarce, and some populations show little to no recovery over the last two decades.

Is Black Coral Endangered?

Black corals are listed under Appendix II of CITES, meaning their trade is regulated because they are vulnerable to extinction if not properly managed​. In Mexico, overharvesting since the 1960s—especially in Cozumel—led to the banning of collection permits in 1995. Yet threats persist from poaching and illegal trade. Black coral grows at an incredibly slow rate—only 8–22 micrometers per year, making it extremely vulnerable to overexploitation. Once removed, it takes centuries for black coral populations to recover, if at all.

Threats to Black Coral in Cozumel

Black coral faces multiple threats, including:

• Overharvesting for jewelry: For decades, black coral has been extracted for the production of jewelry and souvenirs, significantly reducing its population.

• Illegal Poaching: Despite strict regulations, poaching still occurs, threatening the fragile marine ecosystem.

• Climate Change: Rising ocean temperatures and acidification negatively impact coral growth and reproduction.

• Habitat Destruction: Increased tourism and coastal development contribute to water pollution and damage to coral habitats.

  
  

Is Black Coral Illegal to Buy?

While not outright illegal, buying black coral is heavily regulated. Many items sold in tourist shops lack documentation, and buying them could contribute to illegal harvesting. Just because something is available for purchase does not mean it's sustainable or legal. Additionally, it is likely illegal to bring black coral back to your home country. 

Avoid supporting this trade—your purchase could be encouraging the destruction of fragile reef ecosystems.

Can I Bring Black Coral Back to the U.S.?

In most cases, no—and even if you technically can, you probably shouldn't.

Black coral is listed under Appendix II of CITES (Convention on International Trade in Endangered Species). That means international trade is strictly regulated, and bringing black coral into the United States legally requires:

• CITES export permits from the country of origin (in this case, Mexico)

• CITES import permits or declarations on the U.S. side

• Proof that the coral was legally harvested and traded, which is nearly impossible for most souvenirs sold in tourist markets

  
  

U.S. Customs and Border Protection and the U.S. Fish and Wildlife Service can confiscate undeclared coral items and issue fines, even if you weren’t aware of the regulations. Trying to bring black coral into the U.S. without proper documentation could result in seizure of the item, civil penalties, and possible criminal investigation in extreme cases

Also, even if a vendor in Cozumel tells you it's “legal” or “has paperwork,” be cautious. Many sellers either don’t understand the regulations or misrepresent their products.

Bottom line: It’s not worth the risk. Skip the black coral and opt for a souvenir that supports local artisans without harming Cozumel’s reefs.

Black Coral Scams

Tourists should be aware that many so-called "black coral" products sold in markets are not genuine. Scammers often sell fake black coral jewelry made from paper-mâché or resin, which easily falls apart when wet. Purchasing black coral—whether real or fake—only fuels demand and incentivizes illegal poaching.

Can You Dive and See Black Coral?

Yes, but it’s not guaranteed. Most black coral in Cozumel lives at depths between 30–150 meters, meaning you’ll need advanced diving certification and often specialized equipment. Keep in mind that populations are sparse due to past exploitation.
