In that I am also a jewelry artist, I have designed and made a piece of jewelry representing lupus awareness. The Butterfly pendant is made with sterling silver backplate, awareness ribbon of twisted SS wire, 2 teardrop shaped amethyst (purple is the designated color for lupus ribbons) and 2 accent stones. I believe they are chacedony, but am not sure. The seller didn't label them. But, here is the finished piece. I am pleased with it.
