tumbled glass gem marbles

These glass gem marbles are tumbled for a frosted finish like beach glass.  Artists often prefer the tumbled finish because it makes the glass less translucent, so the gem looks not quite as shiny.  The visual effect of these gems is more like a roughly tumbled gemstone.  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
