Detail mistake

First off I just want to say so far this is a great show and hope it gets a second season. Also, great that it is filmed close to home in Toronto, living across Lake Ontario from it. The thing though that I noticed while watching 'The Box' was that in Grand Slam near the end of the episode the necklace that Zara was wearing is given to Jaquan's mother. Yet in Episode 103 Zara is shown to be wearing that necklace. Is this an oversight by the film crew or wardrobe department or did Jaquan's mother decide to return it back to Zara? I know a little detail but one I noticed. :)
