So, you're thinking of reselling that diamond you once thought was the one? Maybe you’ve decided to switch up your jewelry game, or it’s simply time to part ways with that once-loved piece. But here's a burning question – can resale value help you figure out if your diamond is natural or lab-grown?

Let’s dive in. Resale value can definitely give you some hints. Natural diamonds tend to hold their value better over time, thanks to their rarity, history, and overall demand in the market. The thing is, because lab-grown diamonds are created in a controlled environment, they’re generally more affordable when you first buy them. This means when it comes time to sell, they may not fetch the same resale value as a natural diamond.

Here’s the deal: Lab-grown diamonds are still real diamonds—they’re just made with a little help from science. But because they’re less rare, they typically don’t appreciate in value the way natural diamonds might. Think of it like comparing a brand new car to a classic vintage one. Sure, the new car has its perks, but over time, that vintage car might just become a true gem on the resale market.

So, how can resale value help you? Well, if your diamond doesn't hold as much value over time, it could be an indication that it’s lab-grown. On the flip side, if it holds its value better, you’re likely dealing with the natural deal. Of course, to get a solid answer, you’ll want to look for certification, too (GIA or IGI, anyone?).

In a nutshell, while resale value can be a clue, it’s not the whole story. If you really want to know for sure, get your diamond checked by a pro—especially before you try to flip it for a nice return.
