Has anyone took advantage of Tiffany's one time buy back? My hubby got me a round brilliant for my engagement ring, and don't get me wrong I LOVE it! But seeing all the new styles such as the legacy , makes me want to from time to time. For those who don't know, our Tiffany's SA, in 2001, told us that we can sell back our diamond ring at the current price (assuming appreciation) and pay the difference for a ring that costs at least double the original amount. Hope that makes sense! Oh and reason I talk myself out of it is due to the sentimental value. I'd be giving up THE ring that my hubby proposed with. The ring I can see myself giving to my future son or daughter. So if anyone has done this or want to please share!
