Out of an older collection comes this very interesting and unusual specimen.
You do not often see natural pink zoisite, which some would call pink tanzanite.
Zoisite is the mineral name; Tanzanite is the trade name given to the blue/purple varietal.
This unique specimen is mostly pink in color with some slight yellow in the coloring,
along with some purple with greenish yellow at the base.
There is some graphite present on some of the edges of the zoisite.
It has great terminations, very sharp and well formed.
The center of the crystal appears to be yellow in color but has strong pleochroism and can also look pink.
What makes this a very unusual specimen is this zoisite fluoreses yellow under longwave UV lighting.
Zoisite is not known to be fluorescent, which makes this a curiosity that should be more closely examined.
The backside bottom is contacted, as most crystals of this mineral are,
when being removed from the host rock.
