This really comes down to how you view an investment. When it comes to buying a lab grown diamond, many couples would view the lower price tag and environmentally-friendly aspect as a non-negotiable which would it make a lab grown diamond a great investment. If you want a diamond that's guaranteed to be conflict-free, then a lab created diamond is a good choice. However, if you're looking for a diamond that will appreciate in value over time, then natural diamonds are a better investment. Ultimately, it's up to you to decide which type of diamond is right for you.
