To further this note on GIA, & it’s reporting of a stone. even
unseen. I was working as a setter, we shared an office, he had a
client in Toronto who wanted a 5.00 carat stone. My friend showed him
a “GIA, Pre-Cert” meaning a Pre-Certificate for loose stones. That
stone was still sitting in Belgium.
The client actually bought the stone ‘unseen’, just based on viewing
the ‘cert’. How important are these reports? The sale spoke for
itself. When the stone finally arrived, he had it re-appraised again
just to make sure it was the same stone from the GIA report.
Three months ago, I sold a 2.25 carat diamond ‘unseen’, just from
the GIA-Cert. Gerry Lewy.
