[Rockhounds] The last of the Spodumenes

[Axel Emmermann]

Hi Group

 

I just published the last two of a series of 3 spodumene specimens. 

The first is from Brazil and reacts to UV quite similar as the Afghan
specimen that I pyblished some weeks ago, just a lot weaker.

The second specimen is from Finland and also reacts to UV with a weak to
medium strong fluorescence. But in violet laser light the specimen
fluoresces fiercely.

The photo is taken in violet laser light, which requires a very good filter
to stop 405 nm laser light to drown the image.

 

The easiest way to go see is via my blog on this page:

Enjoy

Axel
