Perles en turquoise entre 6 et 10mm Rectangle 90 carat Country of origin:Turquoise beads. Color: Blue, green Sizes: Between 6 and 10mm Country of origin: China (Hubei) Treatment: It contains so few traces of resin that the laboratory was unable to determine it during testing. But working directly with the craftsman I know that he uses it to stabilize the stone and give it strength so that it can be worked. Resin is one of the accepted treatments because it does not change the appearance of the stone, only its strength.
