Description
Mineral(s): Tourmaline var. Watermelon TourmalineLocality: unknown
A small, 0.8 cm diameter slice of watermelon tourmaline in sunlight. It has zones of pink rubellite and very light green verdelite. The slice also has a milky white inclusion in the center.
A tourmaline slice is a sawed and polished section that transects the long (c-)axis of a tourmaline crystal which is typically elongated. With this "plan view" of the crystal, you can see the neat color zonations that you can find in tourmaline.

Did you consider cross-eye stereo shots of your treasures?

It sure does look like something for a stereo image, doesn't it? Unfortunately I don't really know how to take those sort of images nor do I have the proper equipment to actually appreciate stereoscopic imagery. Any suggestions would be appreciated.

What you have to do for this kind of images is to simulate what each of your eyes will see. So you have to take two shots from a slightly different angle.
I use to take the first shot, then rotate the camera about 15 degrees around the object (keeping the distance and avoiding tilting the cam) and take a second shot. Free hand is possible, bad tilting can be fixed using a graphics editor like Gimp. But you'll be surprised what your brains can interprete correctly - with a minor headachy feeling 
To view the images 3D you have to present each shot to the correct eye. To do this you could open them next to each other and with the same size/scaling on your screen and try to squint your eyes until both images appear to merge in the middle. Once they match they should pop up as one image in 3D.
(In case it's weird and you see the background in front and the front moved behind, just switch the images from left to right on your screen and try again)
Enjoy!
Disclaimer: Although I don't have problems viewing stereo images like that I will not take any responsibility for any headache resulting from this kind of action

I do so love how when it comes to certain minerals man is all 'every single shade must have a different name!' (Frankly I want some antozonite; if only there was a place to order it!)
Was this picked up at a shop or gem show?

Usually I'd be able to answer that question for you, but this is a crystal I somehow acquired really early in my childhood, so I can't even remember where it came from! It was definitely not a show though...more likely originated from a shop.
