Wayne or anyone,
I’ve been collecting and reading up on ametrine for years, because
it’s a stone that to me, suggests an actual event. Apparently it has
yet to be determined why the crystals are purple on the free end and
yellow at the base. It sure keeps the imagination going. It’s pretty
much agreed upon that there was an “event” be it heat or radiation or
both and this makes perfect sense to me, especially since it’s mostly
localized to a region (in Bolivia). It all makes sense to suggest why
the color zone cuts across the crystal that is.
I’ve got numerous pieces of natural ametrine, rough and faceted,
cabbed and carved. I just love the stuff and haven’t set any of it
yet. All pieces have a linear demarcation, be it sharp or fading.
I’ve been seeing some pieces though on the web that have drifting or
curved demarcation and even swirled. Even pie shaped alternating
color zones. I always dismissed it until I read up on the Russian
process of crystal growth. I imagine they can start with any shape
seed and grow a citrine core, then finish it off in a purple jacket.
Their material has a very sharp line of demarcation. Lab stuff is
limited by the imagination. But then I saw on the Anahi mine website
a mined specimen slice with the pie shaped color pattern! That sort
of blows my understanding of the flash wave of heat or radiation or
whatever it was that happened.
My question is this. “What the heck?” (for lack of better words) Does
it lie in the crystal growth pattern? Is this a slice of 6 fused
crystals that continued to grow after the suspected event and ended
up at varied heights? Or does this pattern undermine the theory of a
There’s a story we just have to figure out, or really, wait until
someone does so we can read about it. Do you have any theories of
