Accompanied by premium report no. 91020 dated 17 March 2017 from the SSEF Swiss Gemmological Institute stating that the analysed properties confirm the authenticity of these two hundred forty saltwater natural pearls; also accompanied by an appendix stating that the natural pearl necklace possess extraordinary characteristics and merits special mention and appreciation. The described necklace consists of 237 natural pearls of partly remarkable size, which are strung on three regularly graduated strands. The colour of these natural pearls ranges from white to slightly cream, partly with attractive rosé and green overtones, poetically also referred to as the ‘orient of pearls’. Such overtones are due to an iridescence effect caused on the surface of pearls and greatly contribute to their beauty. Assembling a matching selection of natural pearls of this size and quality is rare and exceptional
