opaque glass gem marbles

Opaque glass gem marbles seem to be increasingly hard to find.  Unlike the more common translucent glass gems, opaque gems have a look more like porcelain or polished stone and consequently may be a little more subtle.  Glass gem marbles are sometimes called craft marbles or accent marbles or glass gems. All these names refer to a glass gem that is flat on the back side for gluing to surfaces. Our glass gem marbles are great for picture frames, backsplashes, mirrors, encrusted sculptures, mosaic stepping stones, and even pictorial mosaics
