Silver Bead and Blue Abalone Style Oval Pendant Necklace 16" + 3.5"

This is a pretty silver necklace with small tiny round silver beads with an oval shaped pendant that looks to me like it is half abalone and silver. It has beautiful blue colors in it. Condition = excellent. There is a faint bit of a pinkish color in one area of the reverse of the pendant. I tried to show it in the picture but it is really, really light and hard to see. I just wanted to point it out. Necklace - 16" + 3.5" extender. Pendant 2" x .5" Jewels2B-61 CHECKED
