Dimensions, proportions, and stone placements are cross-checked. Ring sizes are checked as often times while creating a ring it can change.

Polishing and Finishing Checks

Quality of the metal surface is checked if it smooth or not, with no scratches or markings on the surface of the metal. Intricate areas are checked thoroughly as smaller details can be deformed while finishing. Plating is checked for any rough edges.
