who we are

"i will heLp you reach your full potential. i believe in a unique and customized approach for each and every student." ~ Dr. kenneth fogelberg


our approach


Every student is unique. One-size-fits-all approaches will never help you reach your full potential. I will teach you techniques and the  proper way of using each equipment to identify stones and uncover treatments and synthetics.  The course is based on a customized approach, tailored to your strengths and weaknesses in each gemological area.  

Corbeille Gemology is owned by Dr. Kenneth W. Fogelberg, FGA, GG, GP, AJP. 

Dr. Fogelberg is a board-certified obstetrician-gynecologist who has been an Assistant Clinical Professor at three major medical schools. After retirement, he earned a Graduate Gemologist diploma awarded by the Gemological Institute of America in Carlsbad, California.  He also holds a GIA Graduate Pearls diploma and is an Accredited Jewelry Professional. 

Dr. Fogelberg earned his Gemmology Diploma from Gem-A in January, 2019. Members of Gem-A that hold the Gemmology Diploma are Fellows of the Gemmological Association of Great Britain (FGA).

Corbeille Gemology is located in Weatherford, TX and is a GAPP center for the Gemmological Association of Great Britain.  GAPP is a "Gem-A Approved Practical Provider" and is a center which allows Gem-A Foundation students to prepare for their practical examination by learning to use desktop gemological instruments to examine and identify gem meaterials.  Class size is limited to one or two students so Dr. Fogelberg works side-by-side with each student to help them gain the skills necessary for success both on the final examination and for their subsequent career.
