I came across this lovely "Purple Passion Necklace" yesterday at http://valleycreations.etsy.com. Love the mica shifts work done on this piece, and the colors are great!
Seeing this reminds me of Donna Kato's books and Kato clay which I've owned but were sitting in the shelf waiting to be worked on. So, I start making couple of simple pendants.
I think I'll start a "Black & Gold" section in my etsy shop.
Tried mica shifts, not very successful this time but will keep on trying. I'd be delighted if I could achieve what valleycreations did above, lol.
