The Malachite is set in a wire bezel, which is surrounded by a twisted wire 'jump ring', and ornamented with granulation and wire 'buttresses'. The buttress I saw looked like two round wires soldered together. I think it may actually be one wire with a dark shadow line in the center, but I like my imagined element better. The entire assemblage is mounted on a split ring shank (one thicker piece of wire sawn in two at the ends and pulled apart to make the seat).
I'm known for making, drying and saving small bits and pieces to use at a later time. My stock consists of granulation balls, pre set gems, simple bails, and what I call 'micro molds' - tiny molded elements that I use to embellish almost finished designs. Like this artist used many small elements to create interest in what otherwise might have been a rather simple setting.
Reverse engineering is a very helpful mental game to play when viewing any piece of art. Whether it's a full scale bronze sculpture, an intricate piece of wood working (a cabinet for example), or a piece of jewelry. Try it! The exercise may help take your designs to another level.
