Oxidized copper and stones

Just finished a new piece.  I've been moving toward adding more color to my oxidized copper tube pieces, mostly with gemstones.  This is the latest.  I have a tendency to design for myself--i.e.something I would wear (or sometimes something I would wear if I lived a life that included dressing up, which I mostly don't).  That keeps the work relatively conservative.  This one is a bit bigger than I would tend to wear myself, but I like it a lot.  I think the mix of stone shapes based on molecular structures  and copper tube structures based more on engineering forms works well.  Particularly since it corresponds with the mix of color and no-color.
  I think my next step will be to combine the 2 kinds of beads more closely--like a polyhedron where some of the beads are round gemstones and some are copper tubes.  This is tricky because generally the long beads need structures made mostly of triangles, or else they're too floppy, and I tend to avoid triangles with the round beads.  That's partly because too much thread shows in a triangle made from 3 beads, and also because I like the more open look you get with bigger circles of beads.
