Ok, I'm new when it comes to diamonds but while I was cleaning out my closet, I found an old diamond necklace from an ex bf years ago. I was thinking of putting it up on eBay until I read the receipt. Lifetime Diamond Trade-In Policy You may trade in your diamond at least double the trade-in value. The trade-in value is the original purchase price, excluding tax, plus 5% appreciation per year up to 10 years. Now I'm thinking I can get a better deal by trading in this diamond necklace for a pair of diamond studs earring or something. Did anyone here ever try trading in their diamonds? What's the procedure to go about this? Do I just walk into the jewelry store and ask for a trade in? I feel a bit intimidated to walk in, not buy anything and ask for a trade in. :shame: Mods: I'm not selling my necklace, but just asking for an opinion about trade-in policy. Thanks for your understanding.
