Ross Simons 4 Strand Seed Pearl & Blue Stone Necklace W/Carved Pendant

This is a Ross Simons four strand seed pearl and blue stone necklace with carved pendant. This necklace was purchased at an estate sale. I was told that the blue stone is turquoise. However, I don’t believe it is. It does register as a genuine stone but I could not identify it. The pendant is a beautiful carved lady . The necklace metal is marked 925. The metal is gold in color. It is approximately 19” long. Thank you for viewing. (Cab0827231PM).
