Question about New Comment on GIA Report

[TreeScientist]

Just spotted a new type of comment on two GIA reports today that I've never seen before. The comments are in the format "Matches rough examined in Rough# XXX" with the XXX being a number that looks similar to a GIA number. Here's a link to one of the two reports where I spotted this comment:

https://www.gia.edu/report-check?reportno=5191848182&s=1546778614753

Anyone have any idea what this comment is referring to? Maybe something to do with GIA examining particular rough to determine whether it is lab grown or mined? Honestly, I have no idea. But that's the first thing that popped into my head, seeing as I've never seen this comment before the present day, when lab-grown rough is beginning to proliferate.

Would like to hear from the PS community to see if anyone else has spotted this comment before, or if anyone has any insight into its significance.

I think that is part of the mine-to-market, M2M, program. It matches rough diamonds to the polished finished diamonds. Its a way of tracking diamonds from mine to finished goods.

That's really cool! Thanks for the info. Learn something new everyday here.

I guess this is GIA's potential broader-spectrum answer to some of the smaller provenance-tracking programs like the CanadaMark program. With the increased desire among the general public for transparency in diamond sourcing, I'm sure this will be a very popular service.
