This I thought was an easy one but can't find anything like it, can anybody please guide me to find a similar one or with ideas on how to describe it, and also the name of the iridescent stones used in it, it seems to have a signature or mark, but also could just be the pliers when it was done,it measures 19 1/2" L.
thank you all.
I too believe this is labradorite. You might want to read this:

I think it is nicely made. I once posted a ring and was told it was amatuer craftsmanship and that it should have gone on the scrap pile to be redone, but I contacted Nevada Gems and they explained in detail that it was well-crafted and the silver "pitting" could be because it was crafted from a silver ingot. So opinions are just that, enjoy the necklace! 🙂
For those that don't have the time, or the will, or the patience to read the article I posted, thoroughly. I'll post this from the article.
“People who use the term ‘labradorite moonstone’ or ‘rainbow moonstone’ are on a ‘red emerald’ track,” says Hänni. “The historical and global agreement of the term ‘moonstone’ is used only for orthoclase. Labradorite is not a moonstone.”
Moonstone is a potassium sodium feldspar. Gemologically, it has a lower refractive index and lower specific gravity than labradorite. Blue and white are the only colors for a moonstone’s sheen—there is no yellow, orange, or purple.
Labradorite, on the other hand, is a calcium sodium feldspar. It’s also called spectrolite because it produces spectral colors. These colors are produced by interference and diffraction off labradorite’s peculiar lamellar (flat plate-like) growth, not by scattering off albite inclusions. Labradorite has a higher RI and SG than orthoclase moonstone.
“The composition, identification values, and the reason for the light effect are different between moonstone and labradorite,” says Hänni. “There is no reason—except commercial—to call labradorite a moonstone … it’s confusing, and incorrect.”
I have handled both moonstones and labradorite and love both stones. Looking at your pictures, I still believe these are labradorite stones. The one sure way of knowing for sure is to take it to a jeweler or even better a rock hound. The difference is pretty evident when seen in person.
