TJ Gold & Diamond Buyback Guarantee

At TJ Gold & Diamond, we believe that buying a diamond should feel like a confident, long-term investment. That's why we offer a Buyback Guarantee on all loose lab-grown diamonds purchased from us.

‎

How It Works

If you ever decide to sell your diamond back to us, we will buy it back from you. It's that simple.

‎

Eligibility Requirements

To be eligible for our Buyback Guarantee, the following conditions must be met:

- The diamond must have been purchased directly from TJ Gold & Diamond

- The diamond must be in its original condition — unaltered and undamaged

- The original laboratory grading certificate (IGI or GIA) must be presented

- The original receipt of purchase must be presented

‎

Why Lab-Grown Diamonds?

Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. Our buyback guarantee reflects our confidence in the lasting value and quality of every diamond we sell.
