Lifetime Diamond Security
We proudly offer natural mined diamonds and lab-grown diamonds that meet our highest standards of cut, color, and clarity.
On natural or lab-grown diamond purchases over $300, your center and side diamonds are guaranteed against dropping out—without time limit—provided the jewelry item valued at $10,000 or less is brought into a Riddle’s Jewelry location every 6 months for inspection.
If you reside outside the store location area for Riddle's Jewelry, you can mail your jewelry and guarantee to any Riddle's Jewelry location or the Corporate Office in Rapid City. If you have any additional questions or comments, please contact Customer Service.
