This is live geometry, not a pre-rendered picture. The shank, stone seats and claws are solved from the settings on the right, so dimensions and the metal estimate move with the design. It is a precise design specification for discussion with a jeweller; the joined solids, tolerances and production file still require workshop CAD validation before casting or machining. This stone-dependent construction is a concept only until length, width, depth, girdle and relevant stone observations are recorded.
