[Rockhounds] Question on Boracite

[Kreigh Tomaszewski]

Chris W. Korpi ran Pangea Minerals, which no longer exists online. An
online search for Chris Korpi turns up several specimens EX his collection
offered by other dealers.
http://www.classicgems.net/gem_boracite.htm confirms boracite crystals are
small...

*Boracite* is one of the *rarest* of collector's gems. The only facetable
crystals come from the Stassfurt and Hanover districts of Germany.
*Boracite* crystals are very small and cut gems are usually very pale blue
to green or colorless.

The Seaman Museum would get my vote for a likely home for your specimen.
