Police are on the hunt for a thief, who allegedly made off with an unset five carat diamond in Sydney's CBD earlier this week.
About 10am on Tuesday a guy entered the store in Martin Place, police have been told he checked out a five-carat diamond before allegedly swapping it for a stone that looked similar, but of a lesser value.
He then took off and employees called officers when they noticed the stone had been switched.
As for how much a five-carat diamond is worth – it not only depends on the weight (carat), but the clarity, the cut and the colour.
The Diamond Emporium has an impressive array of five-carat diamonds ranging from $59,586 to $497,923.
Officers have today released CCTV footage of a man, who's described of being of Asian appearance with a slim build, and with short black hair, who may be able to assist with inquires.
Check out the footage below.
He was wearing a grey jumper, dark-coloured pants, black Nike-brand sneakers, and carrying a shoulder bag. If you have any info, call Crimestoppers.
