Precious corals from the Corallidae family (Corallium, Hemicorallium, and Pleurocorallium genera) are well known in high-end jewelry industry due to their colorful durable axial skeleton. They exist various colors white pink dark red. One highly appreciated shade is light color, so-called ‘angel skin’. This color most often associated with elatius secundum, species listed CITES Appendix III. However, this has been based on an assumption of visual similarity never underpinned by detailed morphologic or genetic data. In study, we present analysis skin’ coral necklace exceptional size homogeneous quality. Visual observation Raman spectroscopy confirmed that consists genuine, untreated precious material. Following minimally destructive sampling, respectively, drilling 2.2, 2.4, 2.4 milligrams material existing drill-holes, three randomly selected beads were subject a routine identification assay, which sequencing short, taxonomically informative mitochondrial region. identified as not P. secundum but another species. We subsequently sequenced additional DNA fragments one bead compared them against well-represented, curated reference data set Pleurocorallium, including first-ever gotoense, johnsoni, cf. pusillum, uchidai. concluded analyzed belongs norfolkicum complex identical any hitherto published specimens. A comparison further unidentified colony single sample fished Vietnam be completely studied regions. Thus, jewel, discovered new trade potentially also unknown science. implies currently considered list incomplete.
