Excellent company to work with. Very consistent, fast shipping, excellent sales team. Couldnt be happier.

The stones I ordered measure exactly as requested, the cuts are exactly as advertised, color and clarity are exactly what I was looking for, everything is as perfect and as consistent as anything I’ve ever seen. Communication was quick and clear. Very easy to do business with.

I am a precision diamond setter and require top quality melee for my work. My company, Diamonds Direct in Minneapolis loves using Grunberger because of the quality/ consistency of the cut of the diamonds, and especially the customer service they provide to us. We look forward to many more years of working with Grunberger, they are an integral part of our business. Thank you!

Exceptional service and consistent quality! Im in the business making custom jewelry and I rely on the consistent size and quality of their goods.Nothing like nice makes when you are setting micro pave. I count on Grunberger!

Precision Hearts and Arrows melee. Great for precise setting.
