Yes. We proudly stand behind our diamonds and warrant their graded characteristics through the following full legal guarantee and warranty.In the unlikely case that your diamond does not meet or exceed a “4C” grade stated in your order’s Certificate of Authenticity, Mirai Diamonds shall, at your discretion: Accept the return of the diamond and provide you with a refund of the full purchase price; replace the diamond with a diamond that meets or exceeds each of the characteristics warranted.

a. If you make a claim under this warranty, you are agreeing to allow Mirai Diamonds to: examine the original copy of the certificate; try to resolve your claim amicably; inspect the diamond and any gemological evaluation on which you base your claim; remove the diamond from its setting for gemological examination. Diamonds must be graded as loose stones by a reputable, internationally recognized diamond grading lab.

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

c. This warranty remains in effect in perpetuity with the original purchase proof. It covers any lack of conformity to the certified “4Cs” grades this diamond has at the time of sale. It does not cover damage to the diamond that occurs after delivery, including normal cuts or scratches, wear & tear,consequential or incidental damages provided or allowed by an insurance coverage. This non-transferable warranty applies to the original purchaser of the diamond only.

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

Yes, every Miai diamond is either GIA or IGI certified. Each Mirai diamond is crafted using the Chemical Vapor Deposition (CVD) process, which uses heated carbon-rich gasses, rather than high-pressure heat to culture diamond roughs from a seed diamond, and all orders include documented proof of CVD certification.

As the world’s only diamonds produced with a net-zero carbon footprint (Certified Carbon Neutral), our sustainably-crafted stones are made in a zero-emission foundry in the United States’ Pacific Northwest using 100% clean hydropower. Combining proprietary, high-efficiency technology with renewable energy, we’re consciously culturing the industry’s purest, most ethical diamond crystals.
