About this vendor
Deborah Villepigue’s forensic gemology and legal work are a significant part of her distinguished
career. Her abilities in these areas extend beyond traditional appraising, making her a trusted expert in criminal and civil cases related to jewelry, gemstones, and precious metals.
Forensic Gemology:
Deborah has developed a reputation for her forensic testing of jewelry and gemstones, which is critical when identifying fraudulent items or verifying authenticity in high-stakes legal matters. This includes:
• Testing for fraud: Deborah is often called upon to assess the authenticity of gems and jewelry
suspected of being fakes or misrepresented. She uses advanced tools and techniques to
determine if diamonds or other gemstones have been artificially altered, swapped, or falsely labeled.
• Expert analysis for litigation: Her expertise helps determine the true value of items that are
involved in legal disputes, such as divorces, inheritance claims, or insurance fraud. In cases of
estate disputes, her forensic analysis helps clarify the value of personal property, whether it’s for
the liquidation or distribution of assets.
Her work in forensic gemology extends beyond just identifying fraud; she also provides scientific
evidence and reports that are critical in court proceedings, where such expertise can make a
difference in the outcome of a case. Deborah can come to you with her certified mobile lab, or you can come to our flagship office located in Manhasset, NY.

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!

ns 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.
When it came time for me to shop for a wedding set for my wife and I, I knew very little about what to look and where to purchase it. After a month of reading and research I made ...
the purchase. I then insured the wedding bands and the engagement ring. A few years down the road, the insurance company told me I needed to have the jewelry appraised. Again, I knew very little about this process nor where to go for the appraisal. So, I decided to do some research. After asking a few people and doing my own research I searched online for an Appraiser. The Jewelry Appraiser was recommended to me and I am so happy that I decided to make an appointment with Deborah to have our jewelry appraised. Deborah is such a professional, highly skilled and is also very knowledgeable. She made me feel very comfortable from the moment I entered her office. Her Lab and equipment are top notch. Everything is done right in front of you as you sit, watch and listen to the expert review that Deborah provides. During the appraisal process, Deborah explains every step in detail with terms that we all can comprehend. Her attention to detail and knowledge are on full display as she handled my jewelry with the upmost care and professionalism. I watched and listened in amazement. Deborah's skill and expertise were on full display. She made me feel so comfortable. After each piece was appraised, researched, weighed, and photographed, Deborah was also able to tell me exactly how much each piece was worth in today's market. This is very important as it allows me to now insure my jewelry for the correct amount and now I also have expert documentation to assist with an insurance claim in the event of loss or theft. I was very happy to know that the jewelry that I purchased a few years ago has now increased in value by several thousand dollars. Deborah complimented me on the jewelry I purchased and also commented on how well a job the jeweler had performed in matching the diamonds, the placement of the stones and the overall quality of the rings. It was great hearing that I had made good choices and I also felt comfortable and confident in her appraisal. I now have a better understanding of my jewelry. At the end, Deborah told me that I would receive an email within a few days with the appraisal report attached. Sure enough, I received the report in 2 days. Boy was I shocked when I saw how detailed and professional the report is; 24 pages! Deborah, thank you for everything. I value your service and I definitely recommend anyone that needs any jewelry appraised to make an appointment with The Jewelry Appraiser. The quality of service there is second to none...
Working with Deborah, The Jewelry Appraiser, is so much more than an appraisal about the value of an item. My time with Deborah was more enlightening than I could have ever imagine...
d! Deborah filled in a story behind my mother’s ring which gave me insights into my family. Deborah is so knowledgeable and gave so much important background information. The details she shared during the appointment were incredible and helped me connect in a different way with my ring. She then followed up with a thorough, detailed written report. She cleaned my ring for me and advised me about care and repairs to consider. I am so glad to have met and had the opportunity to work with Deborah! She and Louie are welcoming and warm and did a fantastic job. They really care and give you their time and attention. Thank you!

I went to Deborah with a Salt and pepper diamond engagement ring. To be honest, I was nervous going in because it was the first time receiving an appraisal.
Also, due to it being a...
n engagement, it just made me that much more nervous.
Due to this, I made sure to look up and read reviews about appraisers near me, luckily I was able to find Deb and Louie who made this process so much smoother than I could have imagined.
Deb was amazing, I was honestly taken back by her knowledge and enthusiasm.
Her energy and comments were both reassuring and educational. She was able to tell me more about this ring than I could have even thought possible. I left her office extremely content in both my purchase and decision to have her be the one appraised it.
There are truly not enough people who take such pride and care in their work like you and Louie. You two are a dream team and I am eager to come back with any items I would like to have appraised in the future.
