Hi @chrono, I requested the Jeweller to send me any certificates they provide for the ring and he sent me these pictures. I'm honestly not sure what I'm looking at.
From a quick google search i can see that the diamonds are quite high up in the scale. Not exactly sure about the Sapphire though. I'm not sure what "Natural Inclusions and Colour Band" means.
I also did get the jeweller to send me more pictures in a more natural light setting. It does looks 'good' in these pictures. See below.
I think i will just have to wait and see the ring for my self before i take any drastic decisions. Going back to what @qubitasaurus said, the original photos were taken in a light tent. Might look different in natural lighting conditions. BUT still cant excuse the poor mixing of white gold and yellow gold in the ring. It just doesn't look right....
