Put the login gate after you generate a ring, not before. I bounced immediately because it's not worth creating an account without really knowing whether I would be interested. Let potential users invest a little time and start dreaming, so you can take advantage of loss aversion to get signups. Probably also worth adding an option more lowkey than creating an account (which I assume includes setting up a password etc.), like a newsletter that aggregates the best designs every week.
Also, it wasn't obvious to me that the examples in the "Need inspiration?" section were generated, or that I could tweak those designs.
Ha I only added this because my wife doesn't have gmail. I think this is a problem I don't particularly care about for now - I think the parent commenter is correct in saying that the account wall is in the wrong place, so if I move the wall to where the value is (speak to a jeweler) I can defer email verification for a while.
