The amethyst of Namibia !
often the crystals have hematite inclusions ( ENLARGED IMAGE )
This one has 2 enhydro bubbles
Inclusions in pale amethyt crystal: HEMATITE
Other amethyst from Namibia is on the amethyst home page ---->>>>
The amethyst often are heavily included with various
crystals , minerals , and voids and vapor cavities .
this crystal has voids with a crystal shape ! AKA
On occasion these voids are crystal shaped
and are said to be "Negative Crystals ".

                                  The story of Brandberg  Amethyst
99% of the amethyst labeled as "Brandberg" is actually from the near by Goboboseb Mountains.  The
Goboseb Mountains are in sight of Brandberg , which is a national monument and collecting is forbidden
there .   But since those mountains show up on the map and are more well known  , that's the name the
amethyst bear.

The "official" lanquage of Namibia is English .  However ,
Afrikaans and German are commonly spoken as well .  To the left
are examples of skeletal or "fenster" crystals.   Fenster is a
German word that means "window".   You can see why the
skeletal shapes  with their window-like growth caused them to
name them "fenster" crystals.  
Skeletal or "fenster" crystals
amethyst scepter crystal from brandberg region, goboboseb mtns , namibia
This skeletal scepter with amethyst phantom also has
inclusions ( the inclusions are not shown well ) .  And on top of
that it has relic cavities where some mineral formed at the end
of the quartz growth ( but still before growth had stopped as
evidenced by the indentions) .   This secondary mineral then
dissolved away  , leaving strange relic cavities !     
Hematite inclusions------>>>
This crystal has 3 bubbles and is
loaded with inclusions !
The color is exceptional .
This video shows a mobile gas vapour bubble
suspend in a liquid filled chamber .  This is a
two phase inclusion typically referred to as an
"ENHYDRO".-------------------->>>>>>>>
I know this is the Brandberg amethyst page and the following crystal is clear quartz from Brandberg but it is
exceptional with its negative crystal inclusions .    This crystal has numerous negative crystals and most are
fully formed double terminates.  One even has a moving enhydro bubble!   The pictures are so striking that I
am adding them here.
