Transparent materials

Hi, I’m wanting to use something in a piece of jewelry that
resembles glass in it’s transparency, yet wouldn’t be likely to
scratch if it’s used as sort of a frame to contain small movable
pieces. Any suggestions as to what might work, and available
sources for the material? thanks. Lori Colina-Lee

Lori,

I have used cabochon cut rock crystal (quartz) as a covering for a
framed piece. (A framed piece of grass from a famous football
park!)

Yours aye
