BLACK BOX GEMSTONES®
The 4 C’s of Gemstones

Accurate Grading

Each Black Box Gemstone® comes with a grading report from an independent lab or a comprehensive report from Stuller. We guarantee our reports provide accurate grading information. If you feel your Black Box Gemstone® with a Stuller report is not accurate, we will exchange or refund your purchase within 30 days from the date of purchase. At any time in the future, should the gemstone purchased be graded by any of the following independent gemological laboratories (GIA, AGTA or GRS) and the grade of the stone disputed, we will exchange or adjust the price of the Black Box Gemstone® in question.

Free Loss Protection for One Year

To help ensure your purchase is properly protected, all Black Box Gemstones® come with free loss protection for one full year. This provides you with worldwide coverage against theft, loss, or mysterious disappearance. Free coverage of the Black Box Gemstone® begins on the postmarked date of the registration form. There is no deductible.

In the event of a loss, simply return to your retailer for a replacement. This helps to guarantee that you will receive the same quality merchandise as you originally purchased.

Comprehensive Grading Report
and Secure Identification

Each Black Box Gemstone® arrives in a handsome portfolio with a grading report. The report contains information about the size, shape and quality of your gem. Some reports include a brief history of your gem, any treatment information, along with care tips, to help you keep your stone beautiful in the years ahead. This information is provided so that you can better understand the rarity of the gem you are purchasing.

You can have peace of mind that the gemstone you purchased is unique. Each Black Box Gemstone® comes with the added security of a unique identifier. A laser-engraved number matching the grading report is etched on the girdle of the stone. This number allows for proof positive identification. To view, high-power magnification is required
