1. For the pearl necklace we need to clip path on a transparent background, and cleanse the gold of the separators and correct the reflections. Please make sure the separators look polished not matt.
2. For the two image with the sphere ring we need to cleanse the gold and fix the shadow on the metal spheres maintaining the shiny look.
