In:
The Indian Police JournalSummary: It is very challenging to figure out the genuineness of gold items. Numbers of methods are used for gold fraud like gold plating, items made of lead, copper or silver covered with the gold sheet. Large numbers of such type of cases related to gold fraud are registered in various police stations in India. These suspicious gold cases are sent to the Forensic Science Laboratory to determine their genuineness. One of the cases related to fake bullions in which several 20 gm and 100 gm bullions were deposited as exhibits. These exhibits were examined under X-ray fluorescence spectrometer for elemental analysis & Density determination in respect of estimation of purity of gold. The impressions on bullions were also compared with the impression on suspect bullion stamps as well as original bullion stamps. It was observed that the suspicious gold bullions were found fake and impressions on these bullions were made by the suspect bullion stamp. This work may help in the examination of such types of cases and also making investigating agencies aware of such type of fraud. – Reproduced
