Personal touch is the difference

Cash In Your Diamonds is a family-owned and operated buyer of premium jewelry, led by internationally recognized diamond buyer, John Stafford. We are proud of our long family tradition in diamond buying and selling, plus our top-notch on-site gemologists and diamond appraisers.

Easy, Safe, and Confidential

Selling your diamonds through the mail is convenient, but we certainly understand our clients' reservations. That's why we take every precaution to make sure each transaction is insured, securely tracked, and handled in the most confidential manner. Cash In Your Diamonds ensures that you are not only getting the best price for your diamond, you're getting a safe and hassle-free buying experience.

Three Generations of Diamond Buyers

Home to three generations of passionate diamond buyers and sellers, our Dayton, Ohio location has been in the jewelry buying and selling business for over 40 years. During that time, we have earned a long-standing reputation for conducting our business with a high level of trust and personal integrity that has helped us build and maintain warm customer relationships.

Better Business Bureau certified

Our business is certified by the Better Business Bureau and recognized by many other consumer advocacy agencies such as Polygon and the Jewelers Security Alliance. Our passionate diamond specialists stand ready to answer all of your questions about diamond buying, selling, and grading.

Free flight to high value sellers

We are so committed to your service experience that we would be happy to fly high value diamond sellers to our offices to meet personally with our staff for a diamond appraisal and offer. Private bank and house calls can also be arranged. We offer the expertise that comes from decades in the diamond business, and there is never a charge for our opinion or advice.

All certified diamonds are accepted, including GIA, EGL, and AGS. Our diamonds and diamond buying practices must meet the high standards of commitment and quality of Stafford Jewelers, our partner and retailer for many of the diamonds we purchase. We only buy the very best, highest-quality jewelry. Customers know that if they are looking for an heirloom or masterpiece to add to their collection, they will find it at Stafford’s.

We guarantee your satisfaction with your diamond or jewelry selling experience at Cash In Your Diamonds. In fact, we have many diamond selling customers who refer us to their friends and return to sell multiple items. Some of our diamond selling customers have even become diamond purchasers with Stafford Jewelers, our trusted retail partner! And as always, all transactions are strictly confidential. Contact John Stafford today to begin your personal diamond appraisal… and transform your diamonds into cash.
