Some questions on a few bangles made of different materials

[gauntlettgems]

I know it's probably very difficult to get an answer from just a pic but maybe someone recognizes something  Anywho, here it goes  These appear to be wood, kinda rosewood in color  What do you think?

This white one is cold to the touch but not glass  What klind of stone could this be?  

Is this cloissone?  Do  you think it's very old?  Chinese, Japanes, or? 

Thank you for any help you can provide

The last two you posted look like they could be horn (lots of current production coming from Vietnam, but horn jewelry has been around for ages). I love the stuff...have purchased some great pieces from this seller 🙂

Would horn be so light? That's why I initially thought plastic Thank you I'll look

Wow beautiful items on there!

Actually, horn is super-light! That's one of the great things about it...you can make really large pieces that are light as air (Hermes has done a lot of these in the past).
