feel free to save my collages from the FMF forum. I think this site scales the pictures down so if you want them in original resolution, you can give me your e-mail address.

Thanks for the response.

Could you share one of collages? Say the one with Quartz.

I'll get a copy of Microsoft Paint.

Can anyone point me to one of these posters?

Thank you,

I have examined the specimen pictured and believe the reflections on top are all remnants of the original azurite crystal because all contain steps parallel to the other relected azurites. Th ...
