Reggae star Sean Kingston's $500,000 chain was stolen from the mail, after the teen rapper had his sister FedEx a diamond encrusted link chain with a crayon box medallion, from Los Angeles to a jeweler in New York.
The authorities were alerted about the missing bling when the shipped package arrived at the jeweler's shop empty, according to TMZ.com.
Kingston's sister reportedly only insured the extravagant parcel for just $500.
The incident is currently under police investigation in Los Angeles.
The pop icon is best known for his Summer 2007 hit "Beautiful Girls".
