Stuller Black Box Gemstones

Black Box Gemstones®

Purchasing Your Dream

Colored gemstones offer a unique form of self-expression. Your gem may be a symbol of love, a fashion statement, or a celebration of life. Whatever the occasion, gemstones are gifts that are as beautiful and rare as the person they adorn. Every purchase of a Black Box Gemstone® is an amazing choice.

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.
