Glass beads are fantastic. I prefer beading with glass over all other materials. But there’s one exception: miracle beads. They are acryllic beads. The core is finished in a mirrored silver plate which is then coated in multiple layers of lacquer. Light passes through the multiple layers of lacquer and is then reflected back through the lacquer due to the mirror-like properties of the plating. The reflected light radiates a glowing illusion of depth.
I used them in this necklace. You can clearly see which ones they are. They reflect light in different ways so the necklace never looks the same.
