Diamond Foundry's The Forever Guarantee™ 

All of our standard cut center diamonds are created from the Diamond Foundry. Some designs that feature non-traditional diamonds (elongated hexagon shapes and Salt + Pepper stones for example) are recycled and/or post-consumer diamonds.

For all Diamond Foundry Diamonds, we honor The Forever Guarantee™ as detailed on Diamond Foundry's site and included below for your convenience. 


The Forever Guarantee™

We offer a full warranty for our diamonds — a real guarantee & certificate, not just a grading report. Note that reports from third-party diamond labs like GIA expressly do not guarantee anything; they only issue a grading report, never a certificate.

Each of our diamonds is graded by a GIA gemologist according to the strictest gemological standards available.  We then issue a certificate of the diamond's 4C characteristics and inscribe the diamond ID at the girdle with a tiny laser inscription.

You may send your diamond to any internationally recognized independent diamond lab -- GIA, IGI, EGL, GGTL, etc. -- and have our grades validated. We warrant our grades against each and every such lab.

In the unlikely case that a diamond turns out to not meet or exceed a characteristic promised in the certificate, we will, at your option, promptly:

  • accept the return of the diamond and provide you with a refund of the full purchase price; or

  • compensate you for the relatively lower value in cash based on diamond index prices; or

  • replace the diamond with a diamond that meets or exceeds each of the characteristics warranted (for diamonds bought online or at retailers).

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.

If you make a claim under this warranty, you shall allow us to:

  • inspect the diamond and any gemological evaluation on which you base your claim;

  • have the diamond examined by the International Gemological Laboratory (IGI); and

  • try and resolve your claim amicably.

We will respond to your claim as soon as possible but no later than 4 weeks after we have received your claim. You shall direct your claim directly to Jen at jen@shopboschma.com and we will coordinate with the Diamond Foundry on your behalf. 

This warranty covers the lack of conformity of the diamond with each of the characteristics stated on the certificate at the time of sale and does not cover damage to the diamond that occurs after the date of sale.

To be able to claim this warranty, the diamonds must not be exposed to unreasonable force or harmful conditions. This warranty does not apply to product that has been stored or handled incorrectly, abused, altered, treated with the wrong cleaning methods. The warranty does not cover normal wear & tear, cuts or scratches; consequential or incidental damages provided or allowed by U.S. state law. 

This warranty remains in effect in perpetuity with the original purchase proof.

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