Oh no...this is terrible news about the rose gold! I vaguely remember reading something about rose gold on a past thread, but I thought it just had to do with shades initially not being the same...didn't realize that it's fading over time! Is this a common occurrence with Tiffany rose gold? I'm worried now because I just got my first two rose gold pieces last year (Peretti Open Heart and T Hoops) and had a few on my Christmas list this year too. I do remember reading issues about Rubedo years ago as well, but thought that was different as well. Yikes! Would you recommend abandoning ship on the rose gold and exchanging for YG if I get more pieces this holiday season?
Sorry...didn't mean to hijack the thread. I'm also interested in your question about cleaning rose gold if my current pieces begin to fade!
Rose/pink gold changes color over time no matter the brand--that's just the nature of the metal. It's still pretty (imo), but if you want more color-fastness so to speak, yellow gold might be the way to go.
