Crystal Frost Inclusions within Herkimer Diamonds - 12/06-12/2018
Thank you Shannon Haley

samples from the Fonda

Crystal frost is often found at the contact of a Herkimer diamond with the matrix or at a curved contact, presumed to be a contact with hydrocarbon. A beautiful
curved contact is shown in middle of the photo below. There is also well defined crystal frost above this curved contact, shown as curved arches.
The crystal frost page is currently
being updated. Out of the thousands
of photos taken of crystal frost, only
the very best have been added to
this page.

In the previous “What’s new” the
importance of clear windows
through the Herkimer diamond to
the matrix was emphasized. Many of
the crystal frost photos are taken
through these clear windows in the
crystal.
Think of the Herkimer diamond as
capturing and preserving for us a
snap shot of the past - freezing a
moment in time as the crystal grew
over what was there on the host
rock, or in the fluids that surrounded
it.
Photographing the details of these
inclusions gives us an opportunity
to look back in time and gather a few
more clues about how Herkimer
diamonds were formed.
We will be continuing to update the
crystal frost page.

A very special photo of a micro vein cutting through both host rock and druze was added (photo 23a).
