Riddle's Lifetime Diamond Guarantee
Riddle's has provided the best, no cost, jewelry guarantee in the industry for decades, and continues to offer it to our loyal customers. The Gold Guarantee is for purchases over $1,500, and covers the jewelry for ten years. The Silver Guarantee is for purchases under $1499, and covers the jewelry for eighteen months. Both guarantees still cover the loss of a stone up to $10,000 without time limit against dropping out, if checked every 6 months.
This will not change any previous guarantees that a customer may have, but only applies to purchases as of December, 2008. 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.
