Nobody could determine which type of gemstone has been used by Cartier for this necklace!, neither the previous owner, or the Sotheby's expert nor the gemologist to whom the piece was taken for examination. The spherical graduated beads look like turquoise at first glance, but very quickly one notices that it is somehow a different stone, the colour is greener and the veins are not dark, it is more like jade watermarks but too blue for it to be jade. This piece is not only rare, most importantly it is extremely beautiful!, Cartier's bespoke design at its best. The diamond set links between the back double row and the front three strands just light the entire piece! and the small ruby beads that are used to link the hardstone ones just add the right colour contrast to enhance the entire piece. The necklace is dated around 1925.
It will be auctioned by Sotheby's NY on April 14th.
