About Us

Gesner Appraisal Services is located in Tampa, Florida, inside WestShore Plaza, two stores down from Dick’s Sporting Goods.

Graydon Gesner’s enthusiasm for gemology began in 2005 when he became a sales associate with Gesner Estate Jewelry. After several years of gaining experience in the jewelry business, Graydon was motivated to expand his knowledge of gemstones.

He earned his Graduate Gemology Degree, Accredited Jewelry Professional Degree, and the GIA Pearl Grading Lab Degree from the Gemological Institute of America (GIA) world headquarters located in Carlsbad, California which is the world’s foremost authority on diamonds, colored stones, and pearls. He was an on campus student and excelled in all phases of his studies. He received the title Graduate Gemologist as a result of his extensive hands on training and a final exam with a perfect 20/20 score ensuring that anyone who passes deserves this title with high regard and great respect.

Since graduating from the GIA in 2011, Graydon has completed hundreds of appraisals and has graded a vast assortment of colored gemstones and diamonds. His love for gemstones can be seen as he passionately talks about them and works with them on a daily basis.

Please call our Tampa store at (813) 282-1008 or email to schedule your appointment to have your jewelry professionally appraised.

Graydon Gesner, G.G., A.J.P.

What do our Customers saying about us?
  • Graydon took the time to show me specifically how the ring and the gemstone was graded and took the time to answer all my questions. I never felt threatened or pressured throughout the whole process. Thanks for the five-star service.
  • My boyfriend and I were walking through the mall and wandered into Gesner Appraisal Services. The store was packed with customers but we never felt neglected. We had a diamond tennis bracelet appraised while we waited. Awesome service and would highly recommend to all my friends and family.
  • Graydon was a true professional and a true gentleman throughout the process. He takes the time to educate and advise its customers and since he has no vested interest in the jewelry, we felt at ease throughout the whole process. We actually had two pieces that we want to get appraised, and he graciously explained that one of the pieces wouldn't be worth appraising. He didn't charge us for that and we appreciate it.
