These two settings look almost identical to me. I''ve only seen the Tiffany''s Lucida in person, has anyone seen both and can you tell the difference? I''m a couple months out and am trying to decide on a setting for the RING! I''ve narrowed down the diamond cut to either a Regent or Cushion and still comparing settings. Also, typically how does it work....once I purchase a diamond online from say... (GOG), do I then have it set with that company in a similar Vatche/Lucida look alike or have the diamond sent to Vatche to be set? What would you guys recommend?
