I agree with all comments, excellent specimens and photos!

Just two minor comments, please no website marks "encrusted" on the photos, if you want you can locate it in the "File Comment" but not in the photo. Thank you.
Later on I will fix the photos you already downloaded removing these website marks.

Also, please check the point 8 of the A general guide for using the Forum with some rules and tips and try to group the photos instead to publish one photo in each post:

8.-) You can include up to 15 photos or images within each message. To see how to add photos and how to include up to 15 photos/images in a single message follow this link

Thank you again and congratulations again for your collection (and photos ;-)

Thanks for helping me to remove those website marks. Cause I cannot edit my posts, otherwise I'll do it myself.

Thank you. I love photographing, cause it can catch some details that are not easily seen by naked eyes. It adds more surprise to me when seeing some specimens from photos.

That's a good one! I've never seen the effect visualized so clearly.
It's remarkable that LEDs, with their limited and lacunary supply of wavelengths, are able to pick out the interesting features of the wavelength-dependent response of the material so well.

And it's a very nice, characteristically twinned crystal to begin with, too!

Cheers, Gerhard
