Did I get taken?

Sigh. This was an impulse eBay buy. $67. The seller advertised it as Bisbee turquoise with spiny oyster, amethyst, other turquoise, and lapis. My instinct was to pass it by as the center stone doesn’t look like typical Bisbee. When it arrived, I was disappointed to discover the center stone feels plastic like when tapped with my fingernail. The matrix feels gritty and not plasticy.
My questions are 1)Does the center stone appear to be real turquoise? and 2)Is it Native American? (The band / shank appears odd for NA?)

Can you return it? If you paid by Paypal, you might be able to return it as “not as described” even if the seller has a no return policy.

Hmmm. Will look into that.

Thanks @Steve! The matrix pattern looks similar to one of the Kingman stones to me. Feeling a little better.
