Arts and crafts pendant-what are the black stones

Hello all. I have this pretty pendant that i would describe as arts and crafts. Nice big turquoise in the centre, quartz top and bottom and surrounded by small black stones. Might be onyx? Im confident its silver though no hallmark or silver stamp.

Thank you

 

they're all different sizes..and cut differently
so..I'd think glass....but maybe hematite...?

 

NOMB but... It appears to be contemporary. Not sure it would meet the definition of "arts & crafts."

Agreed, looks very modern to me. Possibly Indonesian.

 

The photos are blurry,but looks like the stones might be glued into the setting.

 

Hi,
I have an old gold locket with those same black stones set into a swastika on the back. I thought they were old glass rhinestones that lost their backing, perhaps they started out that way?

No one can ID these stones from a photo. They could be glass, obsidian, onyx or plastic. I agree, they are glued in and probably glass but testing in hand is the only way to be sure.

 

My first guesses were garnet and black "schorl" tourmaline. I agree there's no age on it at all. They don't look like glass; glass wouldn't be faceted that sloppily. The rainbow-y things are labradorite.
