What is the warranty of my diamond?

You can learn more about our Diamond Warranty here.


We are proud to offer a lifetime warranty for all diamonds created by Diamond Foundry.


We stand behind our products and warrant their graded characteristics through the following full legal guarantee and warranty.


In the unlikely case that your diamond turns out to not meet or exceed a 4C grade stated in this Certificate, Diamond Foundry shall, at its option: Accept the return of the diamond and provide you with a refund of the full purchase price; or replace the diamond with a diamond that meets or exceeds each of the characteristics warranted.


If you make a claim under this Warranty, you must allow Diamond Foundry to: examine the original copy of the Certificate; try and resolve your claim amicably; inspect the jewelry and any gemological evaluation on which you base your claim; remove the diamond from the jewelry for gemological examination. Diamonds must be graded as loose stones by an internationally recognized diamond grading laboratory.


The condition of the diamond will be determined by examination under no greater than 10x magnification and by standard gemological techniques. The accuracy of angles and linear measurements will be determined by the following tolerances: ±0.2º and ±0.02 millimeters.


This Warranty remains in effect in perpetuity with the original purchase proof. It covers the lack of conformity of the diamond with the 4C grades stated on this certificate at the time of sale. It does not cover damage to the diamond that occurs after delivery including normal wear & tear, cuts or scratches, consequential or incidental damages provided or allowed by an insurance coverage. This Warranty is not transferable and only applies to the original purchaser of the product.


This warranty gives you specific legal rights; it does not, in any way, affect the rights given to you by law.
