This is a very fine Colombianite Tektite. Colombianite is a beautiful and rare crystal. This Colomianite comes from the La Guajira region of Colombia. This piece weighs 2.5g – 18 x 14 x 8mm
There is sooo much information out there. I can’t speak from experience, so I won’t talk about them with any knowledge but I do know a fine crystal/tektite when I see one and this is one of them. Have a look on the www and see what you find about Columbianites. It’s an interesting read.
Thanks for looking
