I couldn't resist getting a photo of Moss Agate with some real tree moss from our oak trees. A lovely semi-transparent stone with strands of "moss" floating inside. Despite its name, moss agate does not contain organic matter and is usually formed from weathered volcanic rocks. The weave I chose goes nicely, I think.

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.
