A ring is looking for Danique (or her husband)

Dear all, sorry for posting here in English, but I would like to find Danique or her husband. We have found a (looks like) wedding ring on the beach of Banjol on Rab island on Monday. In the ring there are engravings, one of those is a name Danique. As I have found it is a French origin name, but also used in the Netherlands. I see tourists here from the Netherlands often, but quite rarely from France, that’s why I think this ring should belong to a Dutch woman (or preferably her husband). I posted it on Facebook, but I think I am not able to reach Dutch tourists. Could you help me to find her/him? Any ideas are welcome! Here you can find my original post.

Thanks in advance!
