Gary was fantastic and took his time to take us through our recent engagement ring purchase. He ensured that we understood exactly what we had purchased and explained all of the critical items to look out for with our diamond. We are so happy we found him and went here for the grading and appraisal and would recommend to everyone.

Gary was an absolute pleasure to work with and I walked away with far more than a standard jewelry appraisal. From start to finish, he took the time to thoroughly explain every step of the process, sharing his expertise in a way that was both engaging and incredibly informative.

The appraisal report itself is exceptionally detailed, fair, and provides a precise, thoughtful description of my engagement ring. Thanks to Gary’s diligence and care, I feel completely confident having my ring insured.

Beyond his expertise, Gary is genuinely kind, patient, and professional. I highly recommend Gary and Boston Gem Lab!

Gary is definitely an expert, but he is also clearly passionate about his work. I came for an insurance appraisal of an inherited diamond ring, but I also left with a wealth of knowledge about the different cuts, clarities, styles, and types of diamonds that exist out there. My appointment felt like a lesson as well as an appraisal, and I mean that in the best way. I would absolutely recommend this service!

I am incredibly grateful to have found Gary. I sought an appraisal for a sentimental ring belonging to my grandmother, and Gary’s expertise was immediately apparent. Not only is he exceptionally knowledgeable, but he also provided invaluable insights and creative options for the piece's future. The attention to detail in the final appraisal report is second to none. I couldn't be more pleased with the results and highly recommend Gary to anyone seeking a true professional.

Working with Gary at BGL was efficient and easy. He was great to work with, easy to find and people-focused through the process. Excellent experience overall, highly recommend.

I can't say enough great things about Gary at Boston Gem Lab. He was incredibly helpful, friendly, and professional throughout the entire process. His expertise is unmatched—he provided thoughtful advice and guidance that made all the difference as we navigated updates to my wife's engagement ring. I'm truly grateful for his support and highly recommend working with him if you're looking for someone you can trust with your most meaningful pieces.

I cannot enthusiastically endorse working with Gary enough! He was meticulous and thorough but included me in every component of the discussion from the initial consultation on the phone to the in-person appraisal. He has a clear expertise but took the time to talk through every part of the appraisal process and showed me how to inspect our stone using his equipment. He was a timely communicator and we received the formal appraisal form in less than 2 business days! Thank you Gary for your care and hard work!

I recently had the pleasure of visiting Gary for an appraisal of a bracelet I got elsewhere. He’s a courteous professionals who guided me through the appraisal process with meticulous attention to detail and interesting stories.

He examined every facet of the bracelet, offering insights into its makeup and craftsmanship.

My experience with Gary was nothing short of exceptional.

We have nothing but great things to say about our experience with Gary. We brought in a diamond that we had purchased from one of the large online retailers since we'd had it appraised by someone else originally at half the value we'd paid for it. Gary not only took his time to go through every detail of our diamond, but he also took the time to explain the nuances of the current diamond marketplace and why prices can fluctuate so much vs. the online stores. An overall lovely experience that left us feeling much better about our purchase.

Gary was extremely knowledgeable, professional and provided extreme insight when appraising jewelry. He has a keen sense of detail and is extremely meticulous. He answered any questions we had and provided our appraisal in a timely manner. I highly recommend Gary.

I recently had the pleasure of having my pearls appraised by Gary Eber, and I couldn’t be more satisfied with the experience. From the moment I met him he demonstrated a high level of professionalism and expertise. Gary was incredibly thorough, taking the time to explain each step of the appraisal process and answer my questions. His depth of knowledge about pearls and gemstones is truly impressive, and it was clear that he is passionate about his work.

The detailed appraisal report I received was for my insurance company and it was comprehensive and well-written. It also gave me valuable insight into the quality and value of my pearls. I highly recommend Gary Eber to anyone in need of a trustworthy and knowledgeable appraiser. Thank you, Gary, for your exceptional service!

Highly recommend - Gary is extremely knowledgeable and passionate. This is our second time using Gary - the first when my husband had gotten the ring from the jeweler when he was about to propose 3 years ago and again now to get an updated appraisal for insurance. This was my first time meeting him so it was a learning experience for me to learn about the ring and diamond I had. He even explained that the setting I had was not optimal to show the quality and shine of the diamond. Even after getting the ring reset, he helped to show me the GIA inscription for ease of mind.

Gary Ebert is Boston’s premier appraiser of jewelry and previous objects. He approaches his art with passion, and you feel he is truly interested in the history of the objects that are offered for appraisal. Our brief association was stimulating and enjoyable. I recommend him highly. Some of the objects I brought in were truly challenging, and the price of the appraisal was very reasonable.

Gary was actually the second person I called with regards to my ring valuation (I booked another but later cancelled). From that initial conversation I was very much sold with him. He's incredibly informative! I felt confident with him straight away. On meeting he was hospitable and incredibly thorough with his work. I thought the cost covered the appraisal very well indeed. He really takes the time to do a great job.

Gary is amazing! I highly recommend him to value and/or appraise your jewelry in an unbiased and extremely honest way. It is apparent how much he enjoys what he does, and I learned quite a bit from him, and about the historical provenance of the jewelry I had. Definitely worth the trip!

I found Gary Ebert (Boston Gem Labs) through the Checkbook site (it evaluates all kinds of services in the Boston area, and does not accept advertisements). My appraisal needs were somewhat complicated. I couldn’t have been more pleased with Mr. Ebert, who did a careful examination of the objects I brought in, coupled with research based on his vast knowledge. Especially important was the fact that he corrected some serious errors in previous appraisals. Mr. Ebert also offered useful recommendations to jewelers who can perform repairs. The cost of the appraisal was very reasonable.

I am so glad I gave Gary a call when looking for an appraisal for my heirloom 1.87 ct. diamond pendant. Right away I could tell Gary was honest and incredibly knowledgeable. When I met with him in person, he took the time to educate me about my stone. He explained everything from cuts, grading, and current markets to the scope of a GIA certificate (which is quite limited compared to his appraisal). He showed me step by step how he went through the appraisal process in a detailed, exacting and thorough manner. The photos he took of the stone are stunningly professional. Gary had excellent recommendations of where to go for next steps if I wanted to sell the diamond and who to go to to make custom jewelry for me. I could not be happier I found Boston Gem Lab and benefited from Gary's superior services. I would give him a call first before going anywhere else and risking getting hoodwinked about the value of your piece.

I stopped by Boston Gem Laboratory today for an engagement ring appraisal and couldn't have been more satisfied with the service. I wanted Mr. Eber to appraise my diamond for insurance, and to satisfy my paranoia. Mr. Eber made it a safe welcoming environment especially during COVID19. He only allows one appointment in at a time and has the neccessaties like disposable seat coverings, hand sanitizers, masks and disinfectant which is highly appreciative.

Mr. Eber was masterful at conveying details while examining my gemstone in a nonbiased way. He takes his time to explain each and every step while giving and showing examples. Most importantly he educated me about gemstones hence making me a more confident shopper of fine jewelry. Not to mention he makes a great conversationalist!

If you need an expert gemologist to appraise jewelry he is your man even if it is only for insurance purposes. If you are considering him for only an insurance appraisal he is very much worth the few extra bucks than a chain jewelers' appraisal. His document is very well detail that it helps gives you bargaining power in the unfortunate event of needing to file a claim. Notewithstanding, the immersive experience of learning about your gemstone within that hour or so is worth it

I got my engagement ring appraised by Gary from Boston Gem Lab. I was extremely impressed with the enthusiasm, attention to detail and genuine passion that Gary has for diamonds/jewelry. As someone who knows little about the field, the appraisal experience was interesting and beneficial. The appraisal documentation that Boston Gem Lab provided is very detailed. I'm glad i went to Boston Gem Lab for my appraisal needs.

Gary went above and beyond to help me with a piece of jewelry that I found on the beach. He was very professional and friendly, he was not only able to appraise it for me but even helped me get the best price for it when I went to sell it by reaching out to a few of his contacts. Couldn't be happier with the help he gave me

Gary is a certified, knowledgeable, and extremely!!!! Thorough!!!! Appraiser. I wouldn't take my jewelry anywhere else. Extremely affordable, will jump through hoops to solve any issues found, and lastly he's incredibly the nicest person you'll ever meet. I highly recommend him!

I brought in a few rings I purchased abroad to see if they were real and what the quality / value was. Gary was super responsive, and once we set up the appointment (in the Norwalk location) he was very detailed, knowledgeable, patient and his prices were very fair. Highly recommend for any appraisals or Jewelry needs you have.

Gary is a master at his craft. He appraised my family heirloom jewelry with care, thoroughness and honesty, while also providing excellent education to me. He has a forever customer out of me!

I recently had 3 items appraised and 1 evaluated and I must say that the level of expertise and detail I received was like none other. I am so very happy that I found Gary as I like many other's do not understand some of the detail surrounding grading and categories and methodologies. He clarified this information and spent a very long time taking the time to explain the grading appraisal system to me so that my comfort level is much better than it was before I met him. Thank you very much. Cheryl White

My significant other and I were shopping for "the ring" and found an antique one we liked and was in our budget. To make sure it was worth the $3,000 we were spending, we verified the shop's return policy and then sought out an independent (i.e., not affiliated with a jewelry shop) appraisal at BGL. We're insanely lucky that we did--Gary at BGL noted that based on the poor cut of the diamond, the ring was worth maybe 1/3 of what we had paid for it! He was also great at providing information on the era of the ring and cut of the diamond.

We sent this ring back and got a refund, so hopefully we can get a ring we love and that will retain its value.

Gary spent time helping me with questions on an item I purchased elsewhere. Truly a professional & honest person representing the brand! He offered to answer my questions free of charge just to help me in the future! I recommend him for anything & next time he will be my go to for any jewelry inquiry or purchase!

Incredibly knowledgeable and thorough during the appraisal. Had no issues getting our piece scheduled with it. When the piece was damaged, Gary was incredibly helpful and quickly guided us to someone who was able to repair it at a very reasonable price. Highly recommend.

Highly recommend Gary, he's very knowledgeable. The rates are fair but with the detail appraisal seems more of a bargain. Was a pleasure spending time with him learning the craft aspects of the piece and business end I never realized..

Wow! Just Wow. Gary was so helpful! We were verifying the Gems in something donated to Thrifty Threads @United Parish in Brookline. We have been given direction which was worth its weight in gold... pun intended! :-). We are so grateful!

Gary was great! Very thorough work and will walk you through the whole process to let you know what your jewelry is worth and why. I highly recommend!

Can’t recommend Gary highly enough for an appraisal. He was incredibly thorough and educated me every step of the way. This is personalized service that is leagues above what a commercial shop would do.

I can't imagine an appraiser doing a better job explaining all aspects of my great-grandmother's ring than Boston Gem Laboratory. When it turned out that I needed some repair work done, they provided an excellent recommendation on where to go.

Mr. Eber is a great appraiser, not only did he do a thorough review on my (now) wife's engagement ring, but also educated us on each step of the process and what everything means.

Gem Lab was very helpful in the fraud situation I faced in Burma. Gem lab not only diagnosed that my ruby was fake, but also gave me a document signed showing the diagnosis for my visa to see the fraud. Thank you Gem Lab

Gary is very knowledgeable and extremely helpful in ensuring I made the right choice for an engagement ring!

Wonderful service. Gary is extremely knowledgeable. Highly recommend.

Very pleasant to deal with, honest and extremely professional. Highly recommend!

Very professional and thorough. I recommend this business.

Gary is phenomenal! While I only needed an appraisal on my engagement ring for insurance purposes, Gary went the extra mile. He explains each rated quality, why it is important, and provides a detailed report so you are covered if anything unfortunate happens.

Gary Eber is a master appraiser who provides exceptional, high quality appraisals for a fair price. He is fully certified and takes great pride in his work. He spent over an hour appraising an engagement ring, explaining everything in great detail and answering our questions. He also referred us to an excellent goldsmith with whom we ended up working as well. Gary takes great pride in providing the highest quality appraisals. He clearly loves what he does, and it was a pleasure to work with someone so closely and to walk away 100% satisfied. Thank you, Gary!
