A very good specimen of this extremely rare mineral.
Only one finding (three small rock fragments ejected from the Volcano)
of this mineral was achieved to date.
this X-ray checked specimen is the only
available at the moment, together with a few micros (which have not
been X-ray checked).
For this reason it should be added to a museum
Anyway, it will be exchanged only with a restricted
range of specimens such as high quality lawsonite (6-7 mm XX), red
beryl from Thomas Range (10-12 mm XX) or equivalent.
