A very nice specimen. Specimens of the sort shown are often overlooked by many collectors, and that is a pity. Very nice photos too!

Thank you very much for your kind comments, Silvia. I have been a collector of petrified wood, quartz and agates for many years. I think that the petrified wood from Arizona is the most beautiful in the world.
Best regards

Hi Don.
This Lead Hill fluorite has a very nice contrast.

Is also fluorite the yellowish orange portion?

Hello Firmo,
I believe that the specimen is two generations of fluorite. First generation is yellow to yellow orange and second generation blue. The yellow orange is a bit more yellow than the picture shows. I have a another piece that is smaller and I will try to post that in the near future that will show more of the true yellow color. Thank you for your comment.
Best wishes,
Don

Color is more of a problem for me, as I am very color blind. So I go for form way before color
