We couldn't have wished for a better experience! It's an overwhelming process to pick an engagement ring, but on our first meeting with Greg he instantly put us at ease and made us feel so comfortable with leaving this important task to him. Not only is he incredibly knowledgable about the design and jewels he was also genuinely invested in our relationship and story. Greg was respectful of budget and gave us multiple options that wouldn't sacrifice quality. He updated us every step of the way, always welcoming our thoughts and dedicated to turning our ideas into a beautiful product. He truly created the engagement ring of our dreams. We were so happy with his work that we also had him design our wedding band (which of course was perfect as well!). More...

Five star service all around. I was very pleased with the professionalism Greg showed in our meetings. I felt very comfortable throughout the process and knew that he had my best interests at heart. Ring came out perfectly.

Greg was amazing to work with. We had no idea where to start in our engagement ring search, but Greg was very patient and took the time to show us a lot of loose diamond options to choose from. We found the perfect diamond and designed a custom engagement ring that we are absolutely in love with! Thanks again! More...

We were drawn to Jacob Mercari because of the way the company is run with a commitment to ethical options and charitable contributions. This approach and shared values got us in the door. Once there we were blown away by the experience, the customer service and the ring - it was easy, straightforward, pressure free, and enjoyable.

Greg was a pleasure to work with. His communication was constant and timely and he always stayed after hours so that we could meet on our schedule. He has a very genuine approach, not salesy at all, and you could tell he was knowledgeable and very invested in us and our happiness.

He also ensured that the ring was perfect - which included looking at our pictures and helping us customize and build the ring we wanted and also sending it back to the lab when he knew the first version wasn't exactly to our vision. This attention to detail, and his client first approach, was incredibly appreciated.

We would definitely recommend, and will be going back for the wedding bands as well.

I recently purchased a custom engagement ring from Gregory at Jacob Mercari. He made the entire process easy from the first consultation to the day I picked it up. I appreciated the time he took to explain the characteristics of the diamond and overall ring design. The final ring looks spectacular and my fiance loves it. I would definitely recommend contacting Gregory if you're in the market! More...

Greg was a pleasure to do business with.
I initially contacted him for a consultation on a custom engagement ring and he was very accommodating with regards to my schedule.
The consultation had a nice relaxed zero pressure atmosphere and Greg was very helpful and knowledgeable about the diamond selection. He was very enthusiastic with regards to incorporating my ideas into the ring's design and you could tell that he loves his work.
The final product turned out better than I could have hoped. I would highly recommend Greg to any of my friends looking to have a ring made. Will definitely return to him when it comes time to have wedding bands made.

Thank you for using conflict free diamonds. So many companies don't care. Thank you :-)

How do I even begin to tell you how great my experience was with Jacob Mercari. I was impressed with every step of the process, from the initial consultation, all the advice of sizing and design and their honesty and pricing - it was absolutely top notch. I checked out a lot of other places, as an engagement ring is a very big decision and I didn't see anywhere else that matched their level of service. Greg guided me through the design process and offered great advice and was willing and eager to help me make it even better than I could have imagined. I needed my ring rushed and they helped make it happen under a very tight time crunch. The aftercare for the two products I have purchased so far is incredible and shows you they are committed to serving their clients.I've rated these guys inexpensive ($). A quality engagement ring anywhere is a few thousand, but I really was able to maximize my value here. I've compared almost identical stones at other places and been shocked at the price I was quoted. Value is unbeatable at this place.If I could give them 6 stars I would, honestly - skip the big box guys and visit Jacob Mercari. You will not be disappointed. More...
