Meet Marc Gluchov

GIA Trained Gemologist, Senior Buyer

Marc Gluchov is a buyer, seller and appraiser of diamonds, precious gems and metals, antique and estate jewelry, timepieces, coins, and objects d’art. He has traveled and conducted business throughout the United States, Europe, and Asia.


Marc began his business career at the age of 12, when he apprenticed for his father, a master watchmaker. He attended John Carroll University in University Heights, Ohio and completed courses from the Gemological Institute of America in Diamond Grading and Colored Stone Grading, along with attending special classes in Gem Identification and Jewelry Design. 


As a GIA Trained Gemologist, Marc attends many diamond events. He has bought diamonds on the bourses in New York, Antwerp (Belgium) and Ramat Gan (Israel). 


Marc loves what he does. In fact, he taught a class on, “Gems and Gemology” in the adult education program at John Carroll University. Throughout his prestigious career, Marc has earned numerous honors, held many titles - including Registered Jeweler, and was a proud member of:

  • American Gem Society

  • International Society of Appraisers

  • Antique Society of Appraisers

  • National Association of Dealers in Antiques


In 2020, Marc joined the National Estate Jewelers Team of Experts, which includes Gemologists, Numismatists, Horologists, and Precious Metal Specialists. He immerses himself as a buyer in the following Florida cities: Tampa, St. Petersburg, Sarasota, and Bradenton. House calls are available, and Marc works by appointment only. 


When you sell your diamonds, precious gems and metals, antique and estate jewelry, timepieces, coins, and objects d’art to Marc, you can rest assured you will be paid top dollar. He will examine each piece, tell you its value and make you an offer. Marc will never ask you what you want - he, along with all the Experts at National Estate Jewelers, believe it's unethical to ask. Once accepted, payment is immediate. 


Marc served on the Board of Advisors at Cleveland Opera for twenty years. He is a collector of fine arts, with his favorite being French turn-of-the-century posters. In his spare time, he and his wife Sherry enjoy spending time with their amazing children, adorable granddaughter and loving 75-pound greyhound, Bently. 


“For me, buying fine jewelry, coins and the like is fun. If I could, I would do it for nothing.”

- Marc Gluchov
