I let this chunk of pretty crystal design its own copper enclosure. It looks different from every side, and simply gorgeous against the light.

About the copper
I used pure copper wire, oxidized it to achieve a timeless "antiqued" look, and then polished, cleaned and sealed the piece, so that the copper will never tarnish any further or rub off on your skin.
You won't need to polish your pendant, just keep it protected from scratches and bumps against hard surfaces or other jewelry.
