Lab Diamonds

A new and sustainable frontier

Tuesday - Saturday 10am - 5pm


We are open!

Richard Gretz Goldsmiths is the oldest continuously-owned goldsmith shop in the valley.

We have designed and created fine, custom jewelry for over 40 years.

Our team can boast over 100 years of artisan craftsmanship.


We are proud to design and create our jewelry in-house at our Corvallis, Oregon studio. We choose to be different than many jewelry retailers that often send out much of this skill-based labor to other parts of the country or even the world; our value lies in encouraging development, maintaining those skills and keeping those skills here.


We are committed to continually adapting our practices to maintain the traceability and sustainability we feel is in accordance with our high-quality jewelry. From recycled gold to the our eco-friendly lab diamonds; we are always striving for clarity in our eco-impact and practices.

Lab-Grown Diamonds

We are proud to be the only local jeweler to offer Lab-Grown Diamond as an option to our customers.

These diamonds have the same physical, chemical, and optical properties as mined diamonds, so they offer the same brilliance and beauty. The main difference is that they are substantially less exspensive.

These diamonds are widely believed to be the more ethically and environmentally wise choice. Learn more about Lab-Grown Diamond.

Real Customers, Real Appreciation

"Richard designed a new ring setting for some diamonds I wanted re-set. His creation is stunning! Richard has amazing artistic talent and everyone there was so nice, helpful and professional."

Janet G.

"Amazing experience from start to finish. The team at Gretz Goldsmiths are masters of their craft... The rings are completely immaculate, flawlessly beautiful, and everything my fiancee and I had dreamed they would look like. Richard and his team truly are the top notch jewelers in the Benton County area and are second to none. I highly recommend them for any of your fine jewelry needs!"

Michael Joos

"Richard and his team are so professional and very good at what they do. I recently got engaged and they reset my great grandmothers ring into a beautiful setting"
