I sold over five thousand of these jewels totally convinced they were glass since they look like glass , clink like glass, reflect like glass. Not very long ago I heated a needle cherry red hot and it stuck into one. That said they are a super hard synthetic glass acrylic that looks, feels and performs like glass. Out of thousands sold I have never had a return ..... only reorders.
