Here's another example of AZ Tigers Eye.  Not as lovely as Shane's example, but you can see the resemblance to tiger's eye a bit more:

Connie, nice cab.  I had heard of Tiger Eye from AZ and a few other places, but had never seen it.  Its definitely a nice stone.  Binghamite from the Cayunga Iron Range of Minnesota is also know as American Tiger Eye.

a couple of years ago I took a photo of African Pietersite through a mircoscope here are the photos.

I recognize the one pic from the landing page of your site..

Nice pics... !

Cool Pics.  I love really busy Pietersite with swaths of color here and there.  The bright gold colors just glow and jump out at you.  Someday I am going to get a piece of the mostly golden stuff, that is cabbable.  I have a few small golden pieces, but they are rather misshapen and really hard to work with.

  Hey Sara,  i'm cabbing a slab of Labradorite that looks very similar to yours. It's been sitting in my slab box for months and nows it's on the stick. There's lotsa flash and it carves like butter. Anybody know if this material takes a polish?

Here is a photo of a pietersite cab that I did about a year ago.

Now that's the Golden Pietersite I was talking about.  Exquisite cab Bob.  About half Gold and half Blue.

Hey Jon Jon:) Get it cabbed...LOL
your labradorite has more fire than mine and I cant wait to see how it turns out.
I saw a setting one time in a brushed silver pendant blank and it was fantastic.
I will send you one of the blanks if you havent done anything with it yet. I think you will like it:)

Bobby:) Is there no end to the magnificence and magnitude of your treasure trove??? Yet another breath taking design and stone.
I love this place I get to see all these fantastic stones I would have never seen otherwise. I love these natural rocks much more than anything I see in diamonds.
Diamonds are boring comparded to what yall show us:)

just to keep debates alive. and not to say anyones wrong. But Labradorite produces what is called a "Pleiocortic" effect, and it not consider "Chatoyant", or have Chatoyancey"  

Pilocortic effect has to do with a similar idea as Chatoyant, and in essese is about crystal formation on a small level. Which has a effect on the play of light.  But if you look closely, Stones that are chatoyant have fibers to them, or are generally fiberous looking. Stones that have the pleocrotic effect have more tables of color, similar to opals.

Now, my spelling is terrible and i can only find one gem reference to the term "pleocrotic", but it is a known effect in feldspar based stones. IN which Labradorite is part of that family. As is moonstone, sunstone, Nummite, Larinite, spectrolite and more im sure.

Shain you are right.  As with many other ways of classifying rocks, people tend to place stones in groups with other similar stones.  Like you said, the effects are similar, but they are caused by different things.  To the rock specialist, that would be a no no, but to most of the rest of us amateurs, that is what we do.  I tend to think of Nuumite as being rather fibrous.  It seems to be made up of dark fibers that are interspersed with the reflective an kind of iridescent green, gold, or silver metallic fibers.
