After receiving a tip-off of the diamond transaction, security guards in St Lucia were on high alert on Sunday night.
The suspect, a 39-year-old Zimbabwean national, was seen just after midnight outside one of the closed restaurants. He was apprehended by town security and a plastic bag containing seven diamonds worth about R1.5-million was found on his person.
The suspect arrived from Johannesburg reportedly to sell the diamonds to a buyer in St Lucia.
The suspect is being detained at Mtubatuba Police Station for further questioning.
