I believe the artist is Elise Renault. Here is a link to her Fred Harvey
line of jewelry ... which, as you suspected, is made from old discarded
railroad china. https://sculptedarray.com/harv-e/#FredHeadCool stuff. I
think your necklace is shown near...
From the flash of light I see in your pendant, it looks like what is
called "sunstone". Do all the other stones have that effect or is it an
illusion caused by the lighting?
