**Flagship Office in Manhasset, NY**
**Accredited Gem Laboratory Portable Lab®**
Deborah A. Villepigue, GG, RMV, CSM-NAJA, AGA, APPA, ICGA, is the CEO of The Jewelry Appraiser, Inc., located in Manhasset, New York. She is currently recognized under Section Part 36 for New York State.
Deborah has been actively involved in the jewelry industry since 1980. She began her career as a bench jeweler but soon realized that the industry was plagued by misrepresentation and deceit. Deborah set out to promote honesty in jewelry transactions to change the industry in the United States and abroad by providing accurate and truthful information to buyers and sellers. She teaches clients how to sell, liquidate, and donate jewelry. Today, fewer than fifteen individuals worldwide hold her qualifications. She specializes in rough diamonds and colored stones and has designed numerous high-end items for celebrities and private clients.
**Professional Activities**
Deborah is a full-time independent appraiser of gems, jewelry, and all metals. Her company, The Jewelry Appraiser, Inc., operates an independent laboratory certified by the American Gem Society (AGS) in Manhasset, New York. This laboratory is the only independently owned, licensed, and accredited gem lab in New York State, and she also has an AGS-certified portable laboratory. The company maintains a comprehensive library of authoritative appraisal manuals, current price indexes, industry periodicals, and reference books.
At The Jewelry Appraiser, Deborah meets with clients to examine and appraise jewelry. She also designs and fabricates items for diamonds, gemstones, precious metals, silverware, rough gems, and polished gems. She has kept appraisal records for seven years. Additionally, she is a primary jewelry appraiser for New York State, and her company has been retained by the court system for over thirty years to provide expert testimony in both civil and criminal matters. Among her career highlights, she was hired by Christie's auction house to appraise Elizabeth Taylor's jewelry for sale after her death.
Deborah is certified under the Uniform Standards of Professional Appraisal Practice (USPAP), which has led to her expertise being utilized by the US government (including the IRS and US Customs), law enforcement agencies, and all insurance companies. She is also an educator and lecturer on Native American jewelry, gemstones, artwork, and culture, working closely with Native American organizations to design significant pieces of art and jewelry.
Her professional activities extend beyond the United States; she travels globally—particularly to the Far East, Middle East, and Africa—to appraise gems (both rough and polished) and jewelry for buyers and sellers.
**Training and Education**
Deborah has extensive experience across all levels of the jewelry industry. In the 1980s, she purchased colored gemstones, pearls, and diamonds for television productions and prominent retailers. She also designed and manufactured jewelry for major national and international catalogs. American Express employed her to design and manufacture jewelry for its Fine Jewelry Department, overseeing the buying, sorting, and selling of all-natural and treated gemstones and diamonds and their synthetic counterparts. She has consulted on developing gemological equipment, including the GMK microscope and various tools widely used in the gem and jewelry industry. Professionally trained in jewelry design and fabrication, she has mastered casting, hand fabrication, and mass production methods for large chain stores.
Deborah began building her credentials as a Graduate Gemologist (GG) from G.I.A. in New York City. She then obtained her Graduate Master Jeweler (GMJ) certification from the Bulova School of Jewelry. Additionally, she is a Registered Master Valuer (RMV)—the first in New York State. The American Gem Society has awarded her prestigious titles, including Advanced Personal Property Appraiser (APPA) and Independent Certified Gemological Appraiser (ICGA). She is the only ICGA in New York State and one of fewer than fifteen worldwide.

Jan 2025The Jewelry Appraiser in Manhasset made everything smooth and taught me so much more than what I knew about a ring that I bought. I sat alongside Deborah for an hour while she checked out my ring. I learned so much and couldn’t have been happier with outcome and write up for insurance. I highly recommend to anyone looking to get a piece appraised. Makes your life easier and you leave her office with a huge weight lifted off your shoulders. Thank you Deborah

Nov 2025I have been a customer of The Jewelry Appraiser for ten years and I would not think of using anyone else. Deborah Villepigue possesses all the qualities you would want in a jewelry appraiser: she is trustworthy, experienced, knowledgeable, and easy to work with. I first used Deborah in 1995 to appraise my wife’s engagement ring and wedding band for insurance. Deborah provided me with an extensive report on the rings, including photographs, that enabled me to get the rings insured for their replacement cost. My mother had dozens of pieces of jewelry, and we had no idea whether any of the pieces had any value. Deborah patiently went through the entire collection, using her specialized equipment to examine some of the pieces. With her great expertise, we were able to identify which pieces had real value, and which items were simply “costume” jewelry. More recently, my wife decided that she wanted new settings for her rings, to make them more modern and safer to wear, as some of th

Dec 20245-Star Review for Deborah A. Villepigue – The Jewelry Appraiser, Inc.
After recently losing a $15,000 bracelet, I realized the importance of getting my remaining jewelry properly appraised and insured. That’s what led me to Deborah A. Villepigue from The Jewelry Appraiser, Inc. in Manhasset, and I’m genuinely so thankful it did.
Deborah was absolutely amazing. Her service was exceptional, professional, thorough, timely, and incredibly informative. She took the time to walk me through every step of the process, and I left with complete confidence that my appraisals were accurate and reliable for insurance purposes.
What stood out most was not just her expertise (which is unmatched), but the genuine care and connection she offers. I found myself thinking: if I hadn’t lost that bracelet, I wouldn’t have met her, and I’m honestly glad I did. Our conversation was one of those rare, meaningful exchanges that stays with you.
Deborah is the real deal, highly certified, deeply knowledgeable

Aug 2025Outstanding Engagement Ring Appraisal Experience!
I had an absolutely fantastic experience getting my engagement ring appraised. Deborah was welcoming, and genuinely delightful to work with. She LOVES what she does and is so PASSIONATE. She created a comfortable atmosphere from the start. Her expertise truly stands out. She is an absolute expert in her field, and it showed in the clear, confident way she explained every detail of the stone and setting.
She also gave me tips and ideas on how my wedding band has to be designed in order to protect the diamonds on the engagement ring!
The entire process was smooth and handled with exceptional care. It’s obvious that Deborah truly values her clients and takes great pride in her work. I left feeling completely confident, informed, and incredibly grateful.
It was such a fun and pleasurable experience from beginning to end. Deborah is now the only person I trust from now on, and I will happily send all my family and friends to her.

Nov 2025I recently went to Deborah to have my engagement ring appraised and was more than happy! Aside from having well known jewelers recommend her, having the word of mouth recommendations from friends was very reasurring; especially for never having had jewelry appraised before. Having been referred and recommended to Deborah, I was hoping I would be in good hands, but boy was I blown away. Deborah's service was incredible and she was a pleasure to work with, she not only told me details about the diamond, ring, but also explained how it was made and why things (prong placement and metal around pave diamonds) were done certain ways; she also recommended avoiding common cleaning products and explained how to keep it in the best shape possible. I would highly recommend Deborah to anyone who needs anything appraised and let you know you'd be in great hands with someone who is passionate about their work.

The atmosphere was comfortable and welcoming, and I left feeling confident about the value and care of my ring.

Nov 2025We had a family heirloom, a large jade piece & had no idea of its worth. We found Deborah and she was able to come over and assess the value of the piece. Appraisers who can do in home visits are not that common and the visit was priced extremely fairly.
I can’t even say how much she was a godsend at a time that was quite stressful for us. Along with her professionalism, came a genuine joy & love of the precious stones she worked with that shone through. I found her to be such a joy to work with & she was so helpful with follow up questions that we had. Deborah really went above & beyond when working with us and that shows her dedication to her craft and to her generosity.
The report we got back was so detailed & gave us so much insight into our piece; it was more than we could have asked for, & could tell her knowledge was from years of working with the precious stones.
Our family is extremely grateful and fortunate to have worked with her and highly recommend her!

Sep 2025It was a pleasure meeting Deborah to have my jewelry appraised. She was not only a wonderful, friendly person but a true expert in her field. She made me comfortable in knowing how much experience she has as a gemologist. I was present for the appraisal and she explained what aspects she was looking for in determining the quality of the piece of jewelry. She answered all my questions and made me feel confident in her expertise. The final appraisal was lengthy and covered every point including pictures, quality of the piece, condition, measurements, etc. I was impressed with her evaluation and her thoroughness. I would highly recommend her to anyone looking for an honest appraisal.

Sep 2025My visit with Deborah Villepigue at The Jewelry Appraiser was far more than a routine evaluation of my jewelry pieces, it felt like stepping into a time capsule. As Deborah examined each item, she brought its history to life, from its creation to the personal stories it carried. Her insights offered unexpected glimpses into the habits and hobbies of my ancestors and even stirred vivid memories from my own childhood.
She approaches her work with remarkable care and possesses an impressive depth of knowledge, which is evident both in her presence and in the detailed written appraisal report I received. It’s no surprise she is so highly regarded in her field. I wholeheartedly recommend her to anyone in need of a jewelry appraisal, whether for insurance purposes or personal curiosity. She is truly the one to see!

Nov 2025I met with Deborah to get a ring appraised. She was bluntly honest, to the point and extremely knowledgeable. She explained every detail surrounding the diamonds, the good, the bad and everything in between.
I’ve been to many appraisers over the years but this was a totally different and better experience. I felt like she actually cared vs me just being another number. Her industry knowledge blew me away and it felt really good for once to get honesty out of someone. She called out the smallest flaws and explained why I shouldn’t be concerned about them, but still walked me through every step of the way through her VERY robust appraisal process!
Highly recommend her to anyone, best in the business!
