i did look on the website and it says opal.. but its mixed with something else cuz some regular opal jewerly does not look like that. it looks like they handpainted the charms.i do have similar bracelets and i got them at six flags and frontier city.. but i dont know where else to buy these bracelets. they do have some on that website but only a few.

anyway just wanting to know what material it is. so its opal but is it enamel or glass?
if u know where to buy jewerly like this let me know also.
thanks
oh and the color is usually multi color and rainbow like. it reminds me of colorful glass. they are so pretty.
