Our Story
Trust, examined.
GEM grew out of years in the Israeli diamond and jewelry trade. Since 2012 we have seen from the inside how much of this market depends on one thing: being sure of what you are buying and selling.


Our Story
GEM grew out of years in the Israeli diamond and jewelry trade. Since 2012 we have seen from the inside how much of this market depends on one thing: being sure of what you are buying and selling.
Over the years we handled thousands of stones and pieces alongside dealers, jewelers and private clients. We saw paper certificates copied, attached to the wrong item, or impossible to check. We saw buyers hesitate, and good pieces lose value because nobody could prove what they were.
GEM was founded to answer that. An independent laboratory that examines every category of luxury item under one standard, and gives each item a report that anyone, anywhere, can verify against its original record in seconds.
GEM is an independent laboratory with a team of certified gemologists working to a single, consistent standard.
Decisions based on measurement and instruments, not on opinion or pressure.
Complete independence. We do not buy or sell what we examine, and we disclose every treatment we find.
A report is only worth what you can prove. Every GEM report is linked to a permanent online record.
Offices
GEM works across two markets with one standard and one online registry. A report issued in any office can be verified anywhere.
