Sturdy, yet flexible. It could be resized and worn on different fingers. Like how the closure looks ! It could be combined with multiple styles. It is simple, but has a wire twist ;)
looks more flat than hammered...the hammering is subtle. beautiful craftsmanship.
Stone looks faceted, and with more color variety in the photo, it is not. A deep blue cabochon is more like it.
That being said, it is quite pretty and fits perfectly!
