Does this help?
Absolutely. I needed to know it exists synthetically. Thanks!
There is no twinning or growth lines visible in this sample, inspected with benzyl bezoate between crossed polars.
The only inclusions I have been able to find, looking down the long axis of the gem are a sprinkling of what could be termed "breadcrumbs". I will try to get a photo later.
I'm off now for the Ron Ringsrud seminar. Anyone in the bay area? Still time to make it!

Indeed, it is synthetic.
Here is a photo of the "breadcrumb" like inclusions that are visible throughout the stone (60x magnification).
They are typical of hydrothermally produced synthetic quartz.

Thanks Aymeric!
Just wish those russian labs would have such sites where the properties, methods and inclusions are disclosed... Guess it's too much to hope for

No, Gemswallah, you didn't bother to read that the bicolored stone was positively identified as quartz. It has nothing to do with Cristinite (whatever that is).
