MB&B® Gemological Services

   A Limited Liability Company ​

We’re the Best at What We Do

MB&B Gemological Service requires all employees involved in retail to undergo extensive training from the Gemological Institute of America (GIA).  Credentials from the GIA validate their knowledge and understanding of jewelry, gemstones and diamonds. 

Our Jewelry Appraisers are required to attain the GIA Graduate Gemologist credential in addition to other credentials before they can write jewelry appraisals on behalf of MB&B.
