As the owner of S.T.G Diamonds, I proudly guarantee your jewelry for a lifetime against any defects in materials or craftsmanship. Should any defects arise, I will personally ensure all repairs are completed at no cost to you.

S.T.G Diamonds also offers a lifetime trade-up program. You may trade in your original center diamond at full credit toward the purchase of a new diamond that is at least 50% greater in value.

Enjoy one complimentary cleaning and one complimentary sizing. Any additional cleanings or sizings will be subject to a service fee. You're welcome to bring your jewelry in for a free inspection at any time to check for potential damage.

Please note that the warranty will be void if any work is performed on the jewelry by anyone other than S.T.G Diamonds.
