GIA Pi­lots Melee Anal­y­sis Ser­vice

Solitaire - - SPECTRUM -

To ad­dress con­cerns in the gem and jew­ellery in­dus­try about the pos­si­bil­ity of syn­thetic or treated di­a­monds be­ing mixed into parcels of melee, GIA has de­vel­oped a fully au­to­mated sys­tem to rapidly and ac­cu­rately an­a­lyse and sort round D-to-Z melee-size di­a­monds.

The pi­lot for the GIA Melee Anal­y­sis Ser­vice will launch in June 2016 at GIA’s lab­o­ra­tory in New York. Cur­rent clients wish­ing to par­tic­i­pate in the pi­lot should con­tact their client ser­vice rep­re­sen­ta­tive. The ser­vice will be of­fered at all GIA lo­ca­tions, with the roll-out be­gin­ning in the third quar­ter of 2016.

“This sys­tem, which in­cor­po­rates proven in­stru­men­ta­tion, stan­dards and pro­cesses used in GIA lab­o­ra­to­ries, will give the in­dus­try and con­sumers con­fi­dence in the char­ac­ter­is­tics, in­clud­ing colour, of these most preva­lent stones,” said Tom Moses, GIA’s ex­ec­u­tive vice pres­i­dent and chief lab­o­ra­tory and re­search of­fi­cer.

The GIA Melee Anal­y­sis Ser­vice will sep­a­rate nat­u­ral, un­treated di­a­monds from sim­u­lants and po­ten­tially syn­thetic or treated di­a­monds, and sort the screened di­a­monds by colour range. Clients can also spec­ify a size range for their par­cel. The sys­tem ap­plies GIA’s decades of re­search into and ex­am­i­na­tion of treated and syn­thetic di­a­monds, and will process about 1,800 stones per hour around the clock.

The sys­tem can ac­com­mo­date stones from 1.1 to 3.8 mm in di­am­e­ter (ap­prox­i­mately 0.005 ct to about 0.20 ct.) The cost of the ser­vice ranges from $0.08 to $0.30 per stone based on di­am­e­ter, with a min­i­mum of 500 pieces in each par­cel. Once sorted, the melee will be sealed in se­cure pack­ag­ing for ship­ment di­rectly to a third party – upon re­quest and when per­mis­si­ble – or back to the sub­mit­ting client.
