Engagement Ring Markings

Hi,

I recently got engaged and picked my ring from a selection of second-hand ones in a jewellers. It has seven diamonds in a circular cluster on a white gold band. I can tell from the marks that it is '14K 585', but the other marks make no sense to me, and I've googled my heart out. A jewellers i took it to told me it was either European (non-UK) or American. The marks I cannot make out are a small squiggle and a sailboat. Sorry I can't be more specific. I'll upload a photo later if i get time.

Any ideas on maker or date?
Thanks
H
