silver ring and bracelet UNID

[chispa]

Hello everyone, is there anybody who can help me indentify a silver bracelet and matching ring marked UNID (in a rectangle)925?
It looks like the silver has been rhodinated.
Thank you so much,Karen.

Could it be "UNI D-A" ?

Regards, Tom

Hi Tom, I wish it was! No, I already checked the David Andersen-marks, but this clearly is UNID in a rectangle.I thought it might be German maybe.Thank you for your reply,greetings from Holland.
