'HEART-THROBS AND perfect diamonds set girls' 'Hearts On Fire',' screams Just Diamond's press release for its recent party to launch the world's most perfectly cut stones. Two sets of these diamonds were presented to mainland model and actor Wu Bing, and local bachelor-about-town and barrister Kevin Hon. Why? Because these two lads are the 'perfect men' who would be most likely to present their nearest and dearest with such a perfect gift, the release says.
