ARTIFICIAL BLACK DYEING WITH SILVER SALT: Treatment with silver nitrate solutions (AgNO3) is applied since the nineteen thirties to Japanese Akoya cultured pearls. The method was used at the end of the 19th century in the mother-of-pearl industry and natural pearls were also dyed this way. This means that the nucleus remains white, while the outer pearly layer takes on the dark color. The deposition of silver seems to concentrate in the conchioline layer which is often present between the nucleus and the pearly layer. The distribution of silver gets less towards the surface of the pearl. In the case of undrilled pearls diffusion of silver oxide starts however from the surface while in the case of drilled pearls the silver solution will more directly find its way to the border area between nucleus and outer pearly layer. Other Coloration

Beautiful gemstone. Checked to be genuine Tourmaline. Color was light pink. I was hoping for a pinkish purple as in the pictures. Great transaction and prompt shipping. Thank you.
