Chinese Fluorite with blue cores irradiated?

Posted by Jeff Wonders

What is going on I looked and saw a huge Fluorite crystal with blue cores on the Arkenstone Gallery (was listed 14.000usd) these from what I've been told are irradiated when I had a nice one I was basically scorned and chastised that these are altered ? Thoughts anyone

What is the evidence that it is irradiated? Nowadays lots of minerals get irradiated, but too often it's just an unsubstantiated suspicion.

Jeff, there are many locations around the world that produce fluorite with "phantoms" quite naturally. We have several that were collected long before the advent of irradiation of specimens. Enjoy your's and remember that with the advent of the WWW "fake news" travels fast!!

My two cents (for what that' worth)..... If just the core is highly colored, it may be unlikely that it was irradiated artificially - don't think anyone can guide the irradiation to a specific location in the crystal(s) (then again, a Sasquatch passed through our neighborhood last week...). When the crystal(s) grew originally, there may have been a radiogenic source (or different solution chemistry) to make the blue core. Then, later solutions were different, so you now have the colored core surrounded by a not-so-colored rind. Or something like that.

Some high end dealers sell irradiated specimens... some don't realize it is, some are aware, some are open about it. At the Westward Look show a couple years ago I saw a quite large Aquamarine on matrix from Shigar Valley offered by a very prominent dealer, the piece had jet black quartz on it too (which is a giveaway for gamma treatment), one of my friends in Peshawar saw the photo I posted on social media of this piece and mentioned to me he had gotten to see this piece before it underwent irradiation and was sold to western dealers, by a business associate of his.
