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!
Teh unusual suspension of the stone within the chain works well. This is a beautiful and unusual piece and it is an eyecatcher for others. Not too large a stone but large enough to make a statement. I am not much of a color blue wearer but that is all going to change now because of this piece. It is gorgeous and unusual.
