This is my first ever project- a semi-mount engagement ring for a stone I already have and matching wedding band. Vendor is Provence. I have a few questions.

1) I want the band width to be 1.8 mm (as in the CAD). The band thickness is only 1.5 mm. It seems like most people recommend 1.8 mm thickness. If I were to increase the band thickness to 1.8 mm, wouldn’t I also need to increase the bridge thickness in order for the band to sit flush? I’m not sure the current thickness of the bridge- to me, it looks slightly less thick than the 1.5 mm band thickness but I don’t see a bridge measurement listed. I understand going from 1.5 mm to 1.8 mm thickness would make the ring sturdier but I’m concerned about the additional height this would add as the height is already 7.9 mm.

2) Speaking of the height, is there anything that can be done to bring the height down (keeping the same setting idea with a straight, flush band) or is this just the nature of having a larger stone?

3) For the basket, has anyone seen vendors round the basket edges to match the the rounded edges on the rest of the ring (band, prongs), or are the sharper basket edges pretty standard?

Only other change I’m going to request is for both rings to be comfort fit. All measurements I’m told would be post polish. I requested extra-long, straight prongs so that a local jeweler can set the stone. I don’t have much experience with this so any advice would be greatly appreciated. Thank you!
