|Jem Jewelers was founded in 1978 by Joseph Ermigiotti, a master bench jeweler and William Heinz, a diamond broker and jewelry wholesaler. At the time of Bill’s retirement a young energetic Gemological Institute of America (GIA) Graduate Gemologist became Joe’s partner. His name is Steven Petrillo.|
|Unchanged: In 2005, Joe sold his remaining shares to Steve, making him the sole owner. From 2005 to present day, Steve has made Jem Jewelers one of Southeastern Pennsylvania’s most successful prominent jewelry stores. Steve has pledged to keep the integrity of Jem Jewelers offering quality designer styles at affordable prices.|
|Unchanged: In 2011, Steve’s niece Lisa Marie Petrillo, also a GIA Graduate Gemologist, has joined his staff making Jem Jewelers truly a family jewelry store. Jem Jewelers staff includes GIA Graduate Gemologists, GIA Graduate Jewelers, GIA Accredited Jewelry Professionals and experienced sales people and craftsmen. Steve, Lisa Marie, and staff have many energetic, aggressive plans to continue making Jem Jewelers the spotlight of the jewelry industry.|
