Most of our rings can be adapted for any center stone shape, and because we are a custom-based company, we are happy to modify any True Gem design to better suit your personal style preferences. In order to provide the most accurate reflection of what your finished product will come to be, the first step in the modification process is the creation and approval of a CAD render. “CAD” is a Computer-Aided Design software that produces a digital, 2D image of your personalized design, which ensures expectations of the final product are clear and that both parties are on the same page as we work together to bring your dream ring to life. This process will require a non-refundable $250 deposit that is fully credited towards the total purchase amount of the final product. To modify a True Gem design, please contact our design team to begin the process! Please note: If you are on a time restraint due to an upcoming event, it is especially important to keep in mind the estimated 6-week turnaround once production has begun. We also highly recommend taking a moment to review the return policy section on our FAQ Page prior to the start of production on your modified design.
