I rarely write reviews but this place has exceeded my expectations in terms of value, customer service and quality. Andrew is a pleasure to work with and a master of his craft. My wife’s engagement ring, and both of our wedding bands turned out amazing. Not being able to see or touch our custom made pieces left us with some skepticism, but the final product never disappointed. Highly recommend!!

I have worked with Diamond Exchange in Hunt Valley twice, both awesome experiences. First experience was an anniversary ring purchase. Prices were very reasonable, service was awesome. Very polite, professional and helpful.Second experience was a repair on my wife’s engagement ring, which was originally purchased elsewhere. Over the years the setting in the ring failed and some stones fell out. The crew at Diamond Exchange removed the faulty setting, replaced with a new sturdy setting and we upgraded to a beautiful single princess cut, sourced from their network. The price on this was unbelievably affordable and the quality is second to none. I am a Diamond Exchange customer for life.

Fantastic customer service and THE BEST place to buy diamonds. The value for the prices is unsurpassed. 3 of our closest friends got their engagement rings made here, as did we, and all were appraised by a 3rd party for about double what we paid. Beautiful craftsmanship as well.

The service here is amazing. They custom made my wife's engagement and wedding rings and have serviced them ever since. I paid WAY below the chain store prices for rings that were FAR superior in quality. We'll never go anywhere else.

Diamond Exchange is absolutely the best jeweler in the Baltimore area. Andrew is not only accommodating and resourceful, but he is also extremely creative and knowledgeable and can get you exactly what you are looking for.I bought my wife's engagement diamond from here and then later purchased her engagement band from somewhere else. Without any hassle, Andrew was able to take both items and create exactly what I was looking for in an engagement ring. Then, before our wedding, Andrew was able to design a unique diamond wedding band for her, which he sauntered together with her engagement ring. It looks fantastic!Additionally, I wanted a unique wedding band for myself that had her finger print on the inside. Not only was this not a problem, but he was able to get it done in a matter of days so that we had it ready to wear before leaving for the wedding.I can't say enough great things about Diamond Exchange. We are so fortunate to have found a jeweler we now know and trust, and we will certainly be coming back for all of our jewelry needs from this day on!
