Ex Input:
Kate Beckett:  Is it possible it 's an heirloom passed down through generations and that 's why there 's no record of it ?
Javier Esposito: Nah , Peters said that old school cutters fashion diamonds with sharp edges . This _ one _ has smooth edges , which means it had to be cut within the last few decades .
Kevin Ryan: And no customs declaration means it was smuggled in , probably from the country where it was mined .
Captain Victoria Gates: Were we able to connect any of Alice 's clients to the diamond ?
Kate Beckett: We 're still going through them , but no , not yet .
