A 17-year-old Wisconsin teen was arrested after being accused of stealing a $51,000 diamond necklace from her mother and selling it to a jewelry store employee for $100, the LaCrosse Tribune reports.
The paper says the FBI recovered the 4.6-carat diamond necklace before police arrested the teen on Friday on felony theft charges.
The teen, identified as Penelope Friends, was charged Monday in La Crosse County Circuit Court -- but with misdemeanor theft.
According to a police report, an employee of Helzberg Diamonds store offered Friends $50 for the necklace, which the girl refused because she guessed the necklace’s value was "much higher."
Friends then allegedly had it appraised at Rogers & Hollands jewelry, which contacted the FBI because they suspected theft.
Meanwhile, a Helzberg employee approached Friends while on a break and bought the necklace for $100, officials say.
Friends' mother told officials that she thought she lost the necklace during a June move from La Crosse to Chanhassen, Minn.
The Tribune says Friends' mother hopes her daughter spends time in jail to think about the theft.
As for the Helzberg employee, the business said it was against store policy to buy stones from customers. The store's manager reportedly told the FBI that they would discuss the issue with the employee.
According to reports, the employee told the FBI that he was "the victim" and he suspected the necklace was stolen and was trying to "get to the bottom on it." He did not, however, say why he didn't call authorities.
