It's said that "A diamond is forever," and while that slogan has been huge for jewelry retailers, most of them hope you'll adopt the unspoken follow-up into your jewelry philosophy. The full saying is, of course, "A diamond is forever -- until you can afford a bigger one."
Most major jewelry retailers offer trade-in programs where you can exchange your original purchase toward something bigger and better down the road -- provided that you're trading up to something at least twice the value. (This is the Zales policy, which is pretty standard throughout the industry.)
This sounds like a nice idea for the couple who doesn't have the money to buy what they want when they're first engaged, but we have to wonder -- doesn't an engagement ring (no matter the size of the rock) have huge sentimental value? Is this something one could really trade in? Grooms, how would you feel about your bride trading up for something "better" than what you first gave her? Tell us what you think!
