Perfect Hearts & Arrows

I just picked up the package at the fedex location. My wife and I are very excited about the diamond. It looks teriffic. We immediately used the ideal scope to look at the hearts and arrows. Perfect!! I''ve seen the referal card included in the package. If my wife is ordering the second diamond would this be counted as a referal? Just trying to save another $100. We need a second matching diamond to the one I just bought because it''s supoosed to be a pair of ear rings. Can you send me a link to a matching diamond? Best regards from a very satisfied customer
