So long story short, me and my finance proposed to eachother at different times. When he proposed to me he bought the ring in picture 1 and 2. But as you can see the gold isn't the same as the ring next to it in picture 3 and 4.

This is probably because they're not the same, one is 14k gold and the other 18k. Unfortunately my finance can no longer return it so we can't change it to the same gold type.

It looks better in the pictures than in real life. Is there any way to colour the ring? Maybe apply something to make it more shiny since it's very mate? Any advice plz.

Thank you!
