Lebanon Laboratory is an excellent resource to appraise jewelry, gems, and stones of all types. She is certified, kind, and quick to respond, schedule, and reliable to send her appraisal certification as soon as possible. Her decades in experience is reassuring and office is clean, calm, and quiet. My fee was $125 for a pair of diamond earrings but she uses the best technology and is very thorough in her research. I'll be using Lebaron Laboratory again and I highly recommend her services. read more

Alison Lebaron is very knowledgeable and trustworthy. I've used her for over twenty years and she has my total respect.

I came to Allison to get my engagement ring appraised last year. She taught me about my diamond and ways to take care of my ring. I originally scheduled just for my engagement ring, and I had asked her if it was worth getting a ring that I wear for fashion appraised and she said yes. She added that appraisal on without me having to schedule another appointment. She was very kind and honest which made her super trustworthy. She even cleaned my ring for me, and allowed me to look at it under the microscope while teaching me about the stone. I thought this was such a cool experience! My appraisal arrived in the mail shortly after my visit with her. I definitely will come back to her for future appraisals, and recommend her to all of my family and friends! read more

I cannot say enough great things about Alison Lebaron. From the very first conversation, she took the time to truly listen to what I envisioned and helped me turn that idea into the most perfect wedding ring for my wife. Every detail was thoughtfully considered, and her ability to translate my thoughts into a finished piece was nothing short of incredible. Alison is not only kind and genuinely thoughtful, but also exceptionally knowledgeable about her craft. She guided me through the entire customization process with confidence and clarity, making what could have been an overwhelming experience feel seamless and enjoyable. When I finally received the ring, I was absolutely speechless -- it exceeded every expectation I had. If you're looking for someone who truly cares, listens intently, and delivers unmatched quality, Alison is the person you want to work with. I couldn't recommend her more highly. read more

If you need a good forensic analysis and appraisal for your jewelry, Alison LeBaron is the one to consult. She's very thorough; one of the best we've used over the years. She's as personable as she is professional. Very easy to work with. Highly recommended! read more

She's okay, but couldn't assess beyond the basics. Now I have to purchase the tools myself and assess on my own which she should have been able to do. read more

Extremely helpful. Proffered expert advice regarding disposal of jewelry and provided a referral to a business that could meet our needs.

First, let me just start off I reached out to LeBron laboratory via Yelp and received prompt communication back. That right there is a five star quality. I don't see any more. Alison responded right away and that was much appreciated. We communicated back-and-forth and found a time that works for the both of us to get together so she could appraise a piece of jewelry I had. When I had something come up in my calendar and needed to reschedule she made everything as easy as possible to find a time that worked for the both of us. I could not appreciate that more and as someone who is also self-employed, knows how hard it is when people have to reschedule ... it can put a kink in your calendar. The appointment with Alison was straightforward and efficient. She explained everything she was doing. She is a true professional in her industry, and I cannot highly recommend her enough as a gemologist and appraiser. If you're looking for someone to appraise your trusted possessions, I highly recommend giving LeBron laboratories a call. read more

I scheduled an appraisal for just 1 item, but Alison made the time to allow for a second item with no advance notice and I appreciated that. I knew nothing about diamonds (except they are beautiful) before meeting with her, and even though I still know next to nothing, I definitely left with SOME knowledge. She was happy to answer my questions and she explained how appraisers can determine what period the diamonds are from. It was all very interesting. Alison is herself a real gem and I would recommend her to anyone needing an appraisal. read more

I hadn't been inside a jewelry store in the decades since I chose my wedding ring, so when I needed to get a ring appraised as part of an estate matter, I didn't know where to go. Glad to have found Allison! She was very professional and provided not just value of the ring, but insight on the age and style of stones and suggestions for how to handle the estate. She also helped me get my engagement ring resized and even helped me find the perfect ring to replace my long-ago-lost wedding ring. I never have to bother with a jewelry store from now on. I'll just go to Allison for everything! read more

I had a need to determine what jewelry I needed to insure and get appraisals on. Alison had me bring in any jewelry I had questions about and she so patiently went through it with me. She took down the information for the appraisals while I sat in front of her to see what she was doing. She is honest and fair! If you have a need for jewelry appraisal, Alison should be your choice. Thank you for a great experience! read more

Alison is extremely knowledgeable and I'll definitely come back for other jewelry appraisal needs (or to just help me sort through jewelry!)... She appraised a very old wedding ring for me, inspecting and taking down all the relevant data before I left - then mailed the appraisal in a few days. :) read more

Knowledgeable, professional, thorough & prompt I've been having pieces evaluated at this lab for nearly a decade & I've been impressed each time by Ms LeBaron's skill & knowledge of her trade. I'm always confident that I'm receiving an accurate evaluation of whichever piece of fine jewelry is being assessed. Whether antique or modern, you'll receive an accurate appraisal from LeBaron Labs Definitely recommended read more

I found Alison through the National Association of Jewelry Appraisers' website. I was looking for someone with experience appraising antique jewelry. Alison was great!! She was so welcoming and professional. She gave us some great information about the history of our ring. We were able to sit with her and watch while she got the measurements she needed and we received the report via mail the following week. Overall an extremely pleasant experience. I will happily return to her in the future. read more

I found Alison through a recommendation from a friend who used to work for a high end jewelry store in town. Thankful for the recommendation because Alison turned out to be a gem. Friendly, knowledgeable, and quick. read more

I ordered a loose diamond online and when I received it, I was unable to find the GIA laser inscription number to match the GIA report that came with my diamond. I was worried that maybe the Diamond was a fake! So I called LeBaron Labs and made an appointment with the owner, Allison, for the next day. She quickly allayed my fears by showing me the laser inscription on my diamond using her microscope! She is a wealth of information about diamonds, having studied and worked as a gemologist and jewelry appraiser for decades. I enjoyed my visit with her immensely! She sent me an appraisal for insurance purposes for my diamond within just a few days! She is incredibly knowledgeable and friendly! I give her my highest recommendation as a jewelry appraiser! read more

Alison LeBaron, LeBaron Laboratory, is a certified gemologist who does jewelry appraisals in the Granite Bay area. She does the appraisal while you wait, so you don't have to leave anything and come back, which is very convenient. She will then mail you a detailed write-up that you can use for insurance purposes. I have taken several pieces of jewelry to her to appraise and her work is excellent. She is extremely knowledgable and fun to talk to, and I have learned so much about jewelry from my visits with her. Also, her prices are quite reasonable. read more

I met Alison LONG before there was yelp. I bought a beautiful diamond from Diamonds International on a cruise. Once I got on board, I knew immediately that the diamond we selected earlier in the day was not the diamond that was put in the setting. But I also knew I had a money back guarantee. That's how I met Alison. Little did I know that I was about to have my own personal "gemologist." Actually, once you realize that most mall jewelry stores are just a front for a loan company with ridiculously high interest rates, mostly for kids without credit, you will realize that you won't ever even consider buying from a retail shop again. Alison has saved me literally thousands of dollars over the past decade +, and the quality is better than any run of the mill jewelry store even gets their hands on. When I read my return policy from Diamonds International, I discovered that I needed a gemologist that had the highest level of certifications available. That's how I found Alison. I have also learned not to refer people to businesses I have used. You have a great experience with a plumber, then your friend says it was the worst plumber they ever had. So I'm careful not to refer. Alison is my exception to this rule. I absolutely know that anyone I refer will also have their own personal gemologist after one meeting. She's that awesome. Every one I have ever recommended has fallen in love with her too and I highly doubt anyone that has ever had any business with her has ever walked back into a mall jewelry store without feeling sick to their stomach. When you meet someone that loves what they do and always had time to share their knowledge with you, well, I say they are a keeper. I wouldn't even consider going anywhere else for anything jewelry related. read more

Alison is so welcoming and helpful. She is professional and knowledgeable and always helps whether it ls a simple fix or a major purchase. A friend recommended her to me years ago and I have done the same every since. She is awesome! read more
