RAPAPORT... The Natural Color Diamond Association will present a study at the Hong Kong Jewellery & Gem Fair on how coloring in diamonds develops. 
Since 2009, GGTL Laboratories in Liechtenstein has been
analyzing both natural and lab-grown diamonds. The results will be given by
laboratory director Thomas Hainschwang (pictured), in a seminar moderated by Rapaport senior news reporter Joshua Freedman.
The presentation will take place at the Asia Word Expo in
Hong Kong on September 17.
