- Abstract
The article focuses on the necklace composed of 29 larger pearls and a number of smaller pearls and diamonds received by Gübelin Gem Lab for gemological identification. Results of ultraviolet fluorescence, Raman Spectra and refractive index readings show that the pearls were consistent with saltwater pearls. It notes that the pearls came from mollusks that are not used for cultivation. A honeycomb structure was shown by five of the 19 purple pearls.
