Both images are of the same mineral, but one is under UV light.
1.  What is this specimen?  Be specific (this is a variety of a mineral on the list).
2.  After prolonged exposure to UV light, what will happen to the color of this specimen?  
3.  Describe the property demonstrated in Question #2.
4.  Name a chemical difference between this mineral and its "parent" mineral (e.g. Goshenite's "parent" mineral is Beryl).

Sometimes when I post images, they don't load, and sometimes they do. Anyone know a fix?

EDIT: Thanks, OrigamiPlanet!

Copy the image address when you're on the image. The easiest way to put an image is to find it on Google Images, click on it, right click on the image, click "Copy image address" and then paste the link. OR you can open the image you found on a website on to a new tab, it'll bring you just to the image, and then you can just use that URL. That usually works for me, but if you've been doing that as well then I don't know what to tell you.

I'd say I have a 50-50 chance of that working, because sometimes the pictures are so large that this dang computer won't display them properly . I'll go ahead and (try to) change the pics above.

Anyone? Feel free to cheat on everything except the ID portion.

Are the two minerals on the list? I'd say the druzy background is mainly quartz. Would the large crystal be sphalerite? Only thing I can remember about Franklin is that it's full of zinc ore, so that would make the most sense.

You would be correct about both.
