GIA System Detects Lab-Growns In Melee

GIA has launched an automated system that can distinguish lab-grown melee diamonds from natural melee diamonds. According to GIA, the screening technology is accurate and fully automated. It can screen 1800 to 2000 melee diamonds per hour and can sort diamonds by color. The service is available for melee 0.9 to 4.0 mm (approximately 0.005-0.25 carat) round, D-Z diamonds, which must be cleaned prior to submission.
