Gemstone grading organization Gemological Science International (GSI) has identified synthetic white sapphire melee in pendants that were submitted as natural-diamond jewellery.
The near-colourless synthetic sapphires, which were set next to natural diamonds, were discovered by the group’s screening and testing department in New York.
“This finding is a great example of the extraordinary work the team at GSI is doing for the screening and detection of undisclosed lab-grown diamonds and simulants,” said Debbie Azar, GSI’s president and co-founder. “What makes this finding unusual and very atypical was the use of melee-sized synthetic white sapphires.”
“While the industry has taken considerable steps to address this issue, the problem still persists,” Azar added. “We continue to identify undisclosed lab-grown diamonds and simulants in jewellery on a daily basis in all our global facilities.”
Any chance of knowing which manufacturer is doing this?
It is always important to disclose the manufacturer as to be cautious in the future.
