"Precious Coral from deep within the Mediterranean Sea is not the same as the endangered, reef-building coral species which grow in shallow waters nearer to the surface. The reef-building corals that are currently suffering the effects of climate change and ocean acidification are in fact not used at all in fine jewelry. Although they share the same collective name “coral,” reef corals are very different from Precious Coral."
"Today, fishing for these corals follows very strict regulations from the General Fisheries Commission for the Mediterranean of FAO (Food and Agriculture Organization of the United Nations), with restrictions for species protection. The harvesting of this coral below 50 meters is limited to minimum trunk sizes and only to very experienced divers. There is also regular delimitation of protected areas for species protection and longevity." *
