Thanks so much. I'm not sure by what you mean by branded. I know the first one is a girdle inscribed hearts and arrow but the second one is not. There are quite a few diamond brands. For example, Lazar Kaplan, Hearts on Fire, A Cut Above, SuperbCert, EightStar, etc.
Branded goods are usually more consistent in the cut quality and cost more.
As for the total depth, it shouldn t be so strict. The angles are more important than total depth.
