Grunberger Diamonds is an outstanding company! There is not a wholesaler out there who has better quality or brighter diamonds. Their diamonds are always exactly as specified, and our goldsmiths never complain about the sizes provided. They are excellent at communicating if what I requested is not in stock, and if it is in stock, they send it to us incredibly fast. They are a top-tier company, and everyone who works there is extremely competent, helpful, and friendly. Thank you for the excellent work! Thank you for the superb work you have provided Washington Diamond throughout the years!!

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!
