I found Jacob Mercari on internet. At first I was skeptical with Greg. After several discussions. he made me feel comfortable and took his time in explaining the 4c's and provided me options for my diamond earrings purchase - no pressure. It was a surprise birthday gift for my wife. He's very professional and answered all my inquiries in a timely manner. We were very happy and satisfied with Greg. I would recommend him.

Dealing with Gregory Jacobson at Jacob Mercari, was an absolute joy. After painstakingly searching for a professional outfit which you could trust, I couldn't be more pleased to have purchased a ring from the company. My fiancee and I were beyond happy with the outcome of the ring quality, price and delivery time. We will definitely be going back to deal with Gregory Jacobson at Jacob Mercari, and will strongly suggest anyone looking for jewelry to only deal with Gregory Jacobson at Jacob Mercari! Thanks again!

My overall experience with Jacob Mercari was educational, value-added, and fun! And my impressions of Greg as an individual are that he is patient, meticulous about providing quality, and above all trustworthy.Greg far exceeded my expectations with regards to 3 custom rings (1 engagement, 2 wedding bands); however, what truly stands out is not the final product (which is amazing) but rather the process Greg takes you on.He goes above and beyond to invest into you as a customer. What I mean by this is that Greg takes the time to educate you on the industry as a whole, his company, the process, and is more than willing to answer any questions you may have at any time. He does all of this without any commitments from you monetarily or otherwise, and even if you do not make a purchase, after meeting Greg you will be more informed and prepared to make smart purchasing decisions. My absolute favorite part of the entire process is working with Greg to design the rings. He is a great listener and is able to translate your thoughts effectively into a great design. It’s also really helpful when you can touch and feel loose stones and example settings, as you really begin to understand what it takes to put a ring together. As a next step, you work with Greg to review 3D renderings of your design and have an opportunity to make sure all the fine details that truly make your ring unique are taken care of (the graphics are pretty cool too).It’s at this point in the process you leave things in Greg’s very capable hands. He provides frequent updates on the progress of your rings, and he is sure to follow-up if there are questions about the details – I really appreciate that he doesn’t make any assumptions on your behalf and that he ensures you are comfortable throughout the entire process.In the end, what you are left with is something truly unique and something you really feel you’ve had a part in putting together (as opposed to just picking out something off of a retail store shelf).I have and will continue to endorse Greg to my friends and family!

Greg did a fantastic job for us! I trusted him every step of the way, and he was very patient in answering all of my questions and working with me. He was a pleasure to work with--from finding the right stone to designing the whole piece. I would not hesitate to recommend Greg!

I recently purchased a custom engagement ring. Having done my research I knew Jacob Mercari had great ratings, and my experience backs up why they have 5-star ratings time and time again! I vaguely knew what I was looking for prior to my first visit, but Greg worked with me to design the perfect engagement ring! My fiance is over the moon about how amazing her ring is! Initially I feared my tight timeline would be an issue, but Greg made sure the ring was ready very quickly. And the quality... wow! I guarantee you will not be disappointed buying a ring here!

I think I visited 7 different jewellers across Toronto (and online!), but found Jacob Mercari to offer the best selection, value, and service. Instead of pushiness and deception, I found graciousness, excellent knowledge of the market, and integrity. My fiancée loved the ring -- the diamond as well as the artistic setting. Couldn't recommend them higher.

I must admit this was the most unexpected wonderful experience I've had in all my years of shopping for jewelry. I did not know what to expect going in but I think I prefer this than going into a store. It is a private and personable experience which does not make you feel like you are in a rushed situation.Greg was kind, knowledgeable and patient enough to listen to what I wanted, to give me options that lined up with what I needed (rather what she said she wanted, because that's how it really is when you're buying an engagement ring). I really appreciate the services offered and the work done. A truly beautifully designed ring that was ready by the date I said I would have needed it. Fantastic service and exceptional professionalism. I will continue to use his services as he is now my go to jeweler.

If I could give 6/5 stars, I would. My experience with Jacob Mercari was nothing short of perfect. I worked with Greg on my engagement ring, and from the very first meeting through finished product his customer experience was above and beyond. He made me very comfortable with the whole diamond buying experience, gave me much knowledge on the subject and was never pushy with options or even working with his company. We created a custom piece, stayed in budget and my fiance could not be happier with the finished product. I visited numerous other jewelers and can say without a doubt I made the right decision. I highly recommend Jacob Mercari for anyone looking for an engagement ring.

Greg was very responsive to us when we had questions all the way through the process of having an engagement ring made. Even before we committed to purchasing anything, he was quick to respond to emails. Greg is very professional, genuine, and accommodating. He would meet with us on his days off, since we were coming from outside the city. We had very specific requests about the ring and Greg was able to meet all the requests within our budget, and even told us we would be saving money on purchasing lab-created diamonds instead of mined ones. Where we saved on the diamonds, he informed us he could cast the ring in platinum instead of gold. We had a design in mind for the engagement ring, Greg and his team were able to provide us with a render of the ring before committing to casting it, which was nice to see. Included in the price of the ring, was an annual cleaning service, as well as inspecting the ring for damage. It is a nice touch to great service. Very much appreciated. We would recommend Greg to anyone we know personally, and would approach him again in the future for other custom jewelry.

Greg was a pleasure to work with! My engagement ring had diamonds 3 quarters around the band and I wanted to make it an eternity by adding more diamonds. He did this in one day!! Plus he cleaned & polished the ring so it looks bright and sparkly. I am extremely happy with the service, price and the result. Would definitely recommend Jacob Mercari to anyone who's looking for an excellent jeweler in Toronto.

The Mercari team did an amazing job designing an engagement ring for us! Greg was a joy to work with. We went with a sapphire, and Greg was able to provide us with a large selection of beautiful and ethically sourced stones to choose from. The final ring is stunning! The design process really made the ring unique. And the price was great. I definitely recommend!

I approached Greg to design and create a custom engagement and the whole process was thoroughly transparent, professional, and enjoyable. During my initial visit and the selection of the stone, Greg recommended diamonds within my budget that had excellent light performance while still being at a great price. He presents these stones under a single fluorescent light source to showcase their performance under typical lighting, unlike jewelry stores that use multiple pot lights that would make any diamond sparkle. There was complete transparency in the cost breakdown of the stone and the band and I felt no pressure to commit to the deal.I requested a band design with very intricate and fine details. Greg responded quickly to any inquiries and requests. He and his team sent me 3D renders of the design, and we met to discuss changes and refinements to the band until we reached a design that was exactly what I wanted. The final product was perfect, and Greg surprised me with an upgrade of the band from white gold to platinum. My fiancee was thrilled as every aspect of the ring was exactly what she wanted.I am also very happy with the free aftercare services. Greg even met us outside of office hours to make sizing adjustments and to give the ring a polish. I could tell that he cares for his customers and takes pride in his craft. I unreservedly recommend his services.

Dealt with Greg over the last few months and he was very accommodating and texted/emailed me when he found new diamonds meeting my requirements. His hours were flexible and he met with me on weekends because it fit better with my schedule. 5+ stars!

Greg is a caring, genuine, and true expert when it comes to customer service and jewelry making. We are very happy with the services that he provided especially compared to some of the major retailers out there today. His service is customized to our individual needs and he takes to time to involve us in the design and making process. We would recommend Greg to our friends and family with no hesitation.

Greg helped us create our custom wedding bands. At every step he was warm, knowledgeable, and very patient with us. Incredible service, and the rings are beautiful - so glad we chose Greg instead of one of the big jewellery chains!

Greg has been awesome to work with. I had started working with a larger custom engagement ring company as well in order to compare services but chose Greg because it was clear his priority throughout the process really was to make sure we made informed decisions we would be happy with for life - literally zero sales pressure. He made sure to explain everything I needed to know about choosing a diamond and really went out of his way to make sure we could look at all of the different options to consider. My fiance and I are super happy with the final product and with the process. I'd strongly recommend Greg to anyone.

I was actually skeptical when I saw that Mercari had all 5 star reviews. But now I completely understand why... Greg is simply incredible. I've had custom jewelry done before, but Greg's work is beyond what I could imagine a jewler do. He doesn't just do as you say (and does it perfectly), he also makes suggestions on how to do it that makes the piece incredible. With his help, my husband designed my engagement ring which I receive complements on a regular basis. He also made our bands, which were simply incredible as well. I also trusted him to make custom cuff links for my husband and he delivered yet again, perfectly. And when I say perfect, I really do mean perfect. I highly recommend him. He keeps his promises. I trust him wholeheartedly, and he's also very talented and has a special eye for it. I'm so happy my husband found him. We definitely have a jeweler for life now. Thank you SO MUCH Greg!!!
