Jacob Arabo also known as Jacob the Jeweler, was once the jeweler of choice for celebrities from Jay Z to Elton John.

Arabo, who designed Mariah Carey‘s $2.5 million wedding rock, was banned from hosting a charity event on Wednesday for NYC’s Hale House. A spokesperson for the charity tells the New York Daily News, “Hale House completely disassociated itself from [Arabo].”

Arabo is awaiting sentencing after pleading guilty to money laundering and giving false statements to federal agents. He was accused of laundering $270 million dollars for the Black Mafia Family in June 2006. (Source)
