About Us

We are your wholesale diamond and estate jewelry experts, and we’ll help you grow your business.

We’re a Midwestern company with Midwestern values. But what does that mean, exactly?

To us, it means our family-run company operates on the principles of hard work, honesty, and integrity, while promoting a positive culture and always looking at ways to improve. Our customers come first, and we provide service with a smile. These are all values first instilled by our founder, RB Grampp, Sr., and which remain enthusiastically in practice today with his son, Ritchie Grampp at the helm.

Bluestone was founded in 1978 amid the hustle and bustle of Cleveland, Ohio, where RB Sr. (on the back of his motorcycle, no less) decided to enter the escalating gold industry. Once he firmly established himself, it was a natural progression into the international diamond market. Times have changed of course, but our principles have not. Today, we have a large inventory of diamonds, studs, and estate jewelry, and we offer no-cost memo services, free overnight shipping, same-day wire service, and overnight check payments. Our friendly and educated team is ready to ensure we’re your one-stop shop. We are a family, and we treat our clients like family. That’s our Midwestern mindset. Welcome.
