AN EXCEPTIONAL PAIR OF TOURMALINE AND DIAMOND EAR PENDANTS Each set with a pear-shaped paraiba tourmaline, weighing approximately 7.46 and 6.81 carats, within a pear and oval-shaped diamond drop-shaped frame, to the similarly-cut diamond layered surmount and pear-shaped diamond trefoil spacer, mounted in gold, 5.4 cm Accompanied by two premium reports nos. 86453 and 86452 dated 27 June 2016 from the SSEF Swiss Gemmological Institute stating that the paraiba tourmalines are of Brazil origin, with indications of heating; also accompanied by two appendixes stating that the paraiba tourmalines possess characteristics which merit special mention and appreciation. The gemstones exhibit an attractive colour and an outstanding purity. Their colours are further pronounced by its well-proportioned cutting style, resulting in vivid blue hues due to multiple internal reflections. The analysed properties are consistent with those of Paraiba tourmalines from Brazil. Their vivid blue colour is due to a combination of well-balanced trace elements (notably copper) in the gemstone, which are typical and characteristics for the finest Paraiba tourmalines of Brazil. Paraiba tourmalines are commonly heated at a rather low temperature (approx. 450C) to modify and enhance their colour. The colour after heating is considered stable. As for the majority of gem-quality Paraiba-tourmalines from Brazil, the described gemstones show indications of heating. Paraiba tourmalines from Brazil of this size and quality are rare and exceptional Two reports nos. 604803 and 604804 dated 5 April 2006 from the Gü belin Gemmological Laboratory stating that the tourmalines are of Brazil origin, and this colour variety of tourmalines is known as “ Paraiba tourmaline ” in the trade; also accompanied by two appendixes stating that the gemstones possess a saturated and homogenous pure greenish-blue colour, combined with a very high degree of transparency. A pleasant shape and finely proportioned cut provide numerous vivid reflections of a vibrant greenish-blue colour, and the high purity of the gemstones make it virtually eye-clean Please note that two of the reports are more than 5 years old and may require an update US$1,600,000-2,300,000
