The photo you posted is a gorgeous couple. I checked the properties of the photo to see if it would tell me who they were. I didn't learn who they were but I did find an interesting contradiction. The photo comes from a place called Jewels by Jessica but there are absolutely no jewels visible in the photo.
That is, except for the outline of the stiff nipples that are plainly visible. Apologies to you or anyone else on the forum to whom these folks may be kin, but the "pointer sisters" clearly create another contradiction -- this one with the concept of the white dress.
But still, they are a very attractive couple.

All seriousness aside, the "jewelry" is the "wrist ornament" which the woman in the picture seems to prefer wearing on her upper arm.
It seems this is the way the artist sees them being worn:
