Our friends over at DesignBoom, one of the top design communities on the web, have just released these brilliant Concrete Rings as designed by 22 Design Studio of Taiwan.  Smooth and geometric, the concrete rings are available in the Corner Ring style, shown left, and the Rock Ring, shown right.  These concrete-shaped rings are formed around a stainless steel band and fitted to specific finger sizes.  They are in limited supply at DesignBoom, so if you’re as stoned on these rings as we are, you might want to make a move sooner than later…
