Here is Sodalite from Greenland.
I will work on my lighting. Planing to make a black box to photograph my UV minerals

The specimen is about 12mm wide, lighted with my trusty Convoy S2 and EOS 5D II with MP-E65

Edit: Sodalite is the type locality of Ilímaussaq complex, Narsaq, Kujalleq, Greenland, Denmark

This is a famous UV fluorescent mineral. The fluorescence should also be pretty bright, right? It would be interesting to see if UV in sunlight makes a difference in the appearence of this mineral (like what Andrea thought about flowers here: https://www.ultravio...__fromsearch__1).

In northern Michigan, this mineral has been known as 'yooperlite." It is sometimes found on the shore of Lake Superior.

Do you also have a 254nm short wave UV source light to visualize minerals?
These are typically small 4W bulbs with a protective filter.
If you do it would be great to see a comparison between the short and long wavelengths UV fluorescence. Remember to be extremely careful with the UV source lights.

Very nice!
The mineral almost looks like molten lava. :smile:
