Palister Chiadzwa (38) was found guilty of breaching the Precious Stones Act following her arrest in 2006.
Her husband is serving a five-year jail term and was fined US$132 000 after he was convicted of illegally possessing 43 028 diamonds of varying sizes by a Mutare magistrate.
Last Thursday, Palister was fined US$700 or seven months in jail with hard labour.
On October 14, 2006 police detectives on patrol in Marange received information that Palister was illegally dealing in diamonds at Zengeni Business Centre.
They put her under surveillance for some time before approaching Palister, who was sitting in her green Toyota Prado.
A search was conducted and the detectives discovered 2 462 diamonds worth US$18 658 280 in her handbag.
She was arrested and the diamonds were forfeited to the State.
CID Border Control and Minerals Unit spokesperson Detective Assistant Inspector Godfrey Mubaiwa yesterday confirmed the case and sentence.
Palister’s husband, Newman, was thrown behind bars in March and is appealing against both his conviction and sentence.
In June, High Court judge Justice Yunus Omerjee threw out Newman’s application for bail pending review.
Newman, who once laid claim to the title "Chief Chiadzwa", has 12 previous criminal convictions, some of them dating back to 1971.
The crimes ranged from hawking to illegal possession of gold and diamonds.
In 2008, he was convicted of illegally possessing diamonds while he was out on bail after being charged with a similar crime earlier.
Newman rose to national notoriety in 2009 when he reportedly lied to a visiting Kimberley Process Certification Scheme team that there were mass graves in Chiadzwa.
He reportedly made the claims in the guise of "Chief Chiadzwa", a non-existent title as the area is led by a headman who falls under Chief Marange’s jurisdiction.
Newman, however, recanted that claim and apologised a few months before he was jailed for his crimes.
