An ok Wedding band I found luring around the house, I haven’t identified all of the hallmarks but I did manage to see clearly "18" and "750" making this an 18ct gold ring.

The ring itself is very thin…around 2mm and around a size N1/2 - O (in the specifications you’ll maybe notice I’ve marked the ring as unbranded, this is purely because I’m not sure what brand it really is)

If you have any further questions then don’t hesitate to ask
