thens was host to a new Mediterranean Gemmological and Jewellery (MGJ) conference, which featured an international line-up of speakers active in synthetic diamond production and treatments.

The conference was organized by the local Independent Gemological Lab (IGL) and CGLGRS Swiss-Canadian Gemlab. Some topics of the conference included : production, gemmological characteristics, distinctive features and value of Argyle Coloured Diamonds; testing and identification of melee synthetic diamonds and pearls and updated information on the methods of synthesis;comparison of the characteristics of Mozambique rubies compared with Burma’s rubies.

Dr Thomas Hainschwang from GGTL laboratories in Liechtenstein was presenting methods to detect small CVD and HPHT grown synthetics. Branko Deljanin from CGL-GRS in Canada reported on joint findings from GRS and CGLGRS labs on how to distinguish natural Argyle from synthetic CVD-grown blue and treated pink diamonds.

Wolf Kuehn from Gemlab Research and Technology in Canada introduced participant stop or table spectrometers. Dr. Brad Cann from De Beers presented a paper on "Fluorescence imaging of CVD synthetic samples and natural diamonds."

The first day of the conference was devoted solely to lectures on gemology disciplines. On the second day, 30 delegates took advantage of a full-day workshop organized by CGL-GRS on the use of a standard and advanced in struments in detecting 50 natural, HPHTgrown, CVD-grown and treated diamonds.

The success of the conference has ensured that next year a second Mediterranean Gemmological and Jewellery conference will take place at Valencia, Spain on May 7-8 in conjunction with local MLLOPIS gem lab. Events News 16 Volume
