About MB&B Gemological Services

All of our office staff members are Alumni of the Gemological Institute of America (GIA) and have additional training from other industry recognized and respected organizations.    

 

As professional Gemologists, MB&B does not engage in any form of destructive testing, nor will gemstones ever be removed from their mountings.
