Frank Darling offers a lifetime upgrade program on GIA graded natural and recycled diamonds.

Through this program, you’ll receive a credit equal to 100% the original price of your diamond towards the purchase of a new diamond of 50% greater carat, or more.



  • • All GIA graded natural diamonds purchased from Frank Darling are eligible.
  • • Your diamond must be in its original condition.
  • • Any damage to the original diamond will disqualify it.


  • • You will receive credit equal to 100% of the original price toward the purchase of a new diamond.
  • • Credit cannot be applied to a setting.
  • • The price of your new diamond must be at least 1.5x the price of your original diamond.
  • • The credit value will be based solely on the value of the original diamond, not its setting.


  • • If your setting fits your new diamond and is in reusable condition, we can set your new diamond in your original setting.
  • • If your original setting cannot be reused, you may keep the original setting, or we can recycle it for you and provide a discount on a new one.


Your ring comes with a lifetime warranty against manufacturing defects. If we determine your ring has a manufacturing defect, we’ll repair or replace it free of charge.

Damage from everyday wear is not covered by our manufacturer’s warranty.

Please note, our rings are handmade, and subtle variations in craftsmanship are one of the many things that make each item unique. These give our rings character and is not considered a defect.


If you found the exact same diamond on a different website for less, we will match that price.

If you found a similar diamond with the same four c’s on a different website for less, we will explain why that price is lower, and in certain cases, honor or adjust our price. Generally speaking, the price is the price for a reason.
