Speculation that company will sell product arm to focus on mining.
Harry Winston is considering selling its watch and jewellery business to concentrate on mining, according to Reuters.
A source close to the brand told the news agency that the company had begun speaking to potential buyers.
Subsequent speculative reports have thrown out potential buyer names as LVMH, PPR and Richemont but there has been no official statement from any of these companies, or Harry Winston itself.
Earlier this month Harry Winston unveiled its latest collection Water at Harrods in London and this weekend will hold the opening of the Hollywood Costume exhibition at the V&A that has been sponsored by the diamond brand.
