Identification needed please. 24K Gold ring with real diamonds.

[11suttle_a]

I came across this ring which I believe to be 24K gold with diamonds running around the circumference.
I am only 15 years old and found this in a woodland. The ring, unfortunately, does not fit me with an inner diameter of ~ 13 mm.

Can anyone tell me if this is 24K gold and diamond and/or a possible value of the ring? I'm not sure what the hallmark is but it seems like "5920" or "5925" or "5923" followed by the letters "ARTO" or "ART□" but I'm not too sure.

Is there a pic attached? I think the site may be having trouble with dieappearing photos...

925 may refer to Sterling silver

I know it looks pretty silver in the photos but the colour is definitely gold. Not sure if it is silver with a gold plate. Any ideas what the hallmark could be?

I think what partgypsy meant is that the hallmarks indicate that this ring is actually sterling silver with a gold plating - meaning it's not gold at all.

It's impossible to tell from the photos of those diamonds are real, but as a silver ring it's not exceedingly likely and the ring would have a pretty low value regardless.
