Featured Looking for age/region of gold overlay bracelet

Don't think I have the right terms for this but the bracelet is rose gold on the back, hollow links, with rose gold pierced floral appliques on top. Each is slightly different, held by two rivets. The black material is glossy; one link has a bit of damage and the spot looks like chipped glass, a bit of dark brown to it.

The safety chain and spring-ring are a different color, perhaps later addition. The backs of the links are the same even tone, my pix didn't do them justice.In fact, there are no wear spots on the edges or flat surfaces. Theo oval box clasp has engraved design on top. No marks. Tests okay on 10K acid, may be 9K overall. Is there a style or period to which I can assign this?

Thanks for sharing your thoughts!

 

I'd guess Damascene, Spain?

 

Yes, they look similar but damascene uses metal hammered into a metal surface, not pieces of pieces metal riveted thru glass or stone onto a metal back plate. The mystery continues but thanks!

 

The dark background may be niello.

 

But it chipped at the edges so it had some thickness. I thought the black material in niello ware was an inlay, not a smooth surface unto itself upon which other metals were riveted?

 

It is. Niello is traditionally cast iron with other metals hammered into it. The results are smooth. This is another kettle of fish entirely. The gold front and back look pinned together, maybe through some sort of resin. I wish Bear was still around; I bet she'd recognize it.

 

Hmm, I did mention that the gold tops were cut-out pieces and riveted thru the black into the back plates...

 

You did, but to anyone mentioning niello or damascene this might not compute.

 

Ok, I understand, thanks!
