Ohh... I love this one just as much as Imperia. But this one, I would pair with a starkly simple white dress, fitted bodice and floating skirt, wide neckline and lots of collarbone showing. Add an elegant antique updo with strands floating free and a delicate black ribbon around the waist as a sash -- the effect is ethereal, ghostly, an image of forgotten luxury that has faded only into memory with the years.
With the jet black jewels and the dark metal holding them in, and twisting around in its elegant ways, I look at this and think it belongs around the neck of a character malevolent in nature, bringing in an everlasting starless night filled with brutal pain and death..
.. or something like that. It's pretty, and when I see it, I think "evil." Or maybe it's just the way the light is on the photo.
