I was pretty disappointed with the quality.  The 'gems' are very plastic looking.  Mine arrived with 2gems missing and nowhere in sight.  There was visible glue around the edges.  Hard to tell from the pics, but the metal is black (it looked a bit silver from the main picture). Luckily I am hanging it in a niche that is a good 12 feet from floor level, so hopefully they will look ok from far away.
