Ok I believe these to shells of some sort, cold even in a heated room, hard and hard to bite with a nice iridescent glitter effect, very heavy and the pieces themselves are heavy for the size.
Other than floating them, (they sink) biting them to test the hardness and bending a pin on them. What else could I do to see if they are shell or from the sea.
Its a bangle bracelet with a modern stretchy string.
Hey you!!! Well, I'm absolutely no expert that's for sure but I do know that abalone is a shell. I also know that they show up in the market place dyed and possibly reproduced from other materials. What I find interesting about yours is the crosshatch looking pattern on the pieces which makes me think they are reproduced and not shell at all. I have a few full halfs I will show you so you know where the material comes from naturally.
But for faster reference...here you go!

And then there is Paua shell, which most people call abalone and it's not. Hope I didn't confuse you more!
I thought it was endangered but wanted to make sure before I said so. I also forget that not everyone knows about California...(that's where I've always lived) These shells were used by so many people here back in the 70's as ashtrays. The only thing that ruined them was when the got dropped. Some great info here:
