Geology 102 for Gemologists:

The Natural Processes that Form Colored Gemstones

Thursday, April 1 at 10:00 a.m. PDT

Speaker: Wim Vertriest

Wim Vertriest is the supervisor of field gemology at GIA Bangkok.  He oversees the field gemology department and curates GIA’s colored stone research collection.

Gemstones require extraordinary geologic circumstances to form. Not only do different minerals need to meet under the right conditions and crystallize, but certain rare elements also need to be part of the mixture for the crystal to be the right color.  Tune in as Wim Vertriest builds on the earth science previously introduced in “Geology 101 for Gemologistshttps://www.youtube.com/watch?v=mDIRqF_02DE”  to explore how alexandrite and spinel form in the earth’s crust and why pegmatites – an igneous rock that is the source of an incredible variety of gems and mineral specimens – is known as ‘natures treasure chest’.
