Hi gurus. I don't really know much about the stone but I've recently fell in love with Morganite. I am wondering is natural heat the only treatment or are there BE and diffused treatments like in Sapphire?

Thanks for your help.

neither Be, nor bulk diffusion on morganite.
ciao

Nice to hear, Morganite is my favourite as well! (for the moment at least :wink: )
I have heard of irradiation on morganite, but that may or may not be true. At least I got rather surprised... :?
The ordinary heat removes orange/brown/yellow undertones and leaves only the pink. The result is often a very light pink stone.
Morganite is one of those stone where the value doesn't increase for unheated material, as corundum often do(if the colur is fine enough)
But from a collector's point of view, it's always nice with 100% natural gems :)

I found myself standing in the office of a German guy yesterday who is specialized in blue topaz. The furnace in the next room told me we dealt with a colour creator. Then my eye fell on a weird dark blue stone next to a few pink ones and I asked what it was. The reply was somewhat surprising: beryl.
A yuckie green to start with it went a dark slightly greyisch blue after irradiation. Ok... I could kind off imagine that but then came the interesting part: further heating produced morganite...
So: yuckie green + irradiation ---> blue + heating to 500 degrees celcius ----> morganite...

there is so much more under this sun... So much more to learn...

Spauwe,

Did he tell you whether or not the morganite color is stable? I've seen lots of irradiated blue beryl (which is known to fade) but I've never heard that morganite can be created from this stuff. Now I want to get a piece and try it! :D!

As far as I know, irradiation turns pink morganite into blue beryl.
Here's a "Blue Morganite" Click Here

interesting comment about the irradiating of beryl then heating to produce morganite ... can anybody point me to some info on this .. reason is I found a site with some really nice morganite at a decent price ... they claim heat only treatment but if it isn't permanent ( the treatment mentioned) then the price suddenly became very expensive indeed??

Had a few more chats with that fella since. The pink is stable, he further mentioned that in his opinion most morganite hitting the market these days comes from this treatment... He's a second generation Idar gem dealer and sit's with his nose right in the action. I'm tempted to trust his statement.

From what I've learned with the brittish gemmological association there is no 'just heating' any colour beryl into morganite... But colour treatments with beryl are a topic open for research, maybe it's possible.

Hi,

The treatment is with cobalt-60 gamma rays. Stable treatment.

Hope that helps

The irradiated morganite is a stable color, some of the is irradiated in a Brasilian gamma facility and comes from apheganistan and pakistan and even Brazil produce such material that use to be a goshenite (colorless variety of beryl) before enhancement. Concerning about blue irradiated beryls they are name maxixe beryl and they are unstable color for sure, but I would like to point out the color is not the same of aquamarine, thats a diferent blue that can be distinguishe easily.

Mauricio, welcome to GO and thanks for sharing your insight as an "insider" at a Cobalt-60 irradiation facility. I hope you enjoy it here and have a chance to share more of your knowledge with us.

:D
