 Silkstone, this was very hard to dome and I could not figure out why. Brown and black areas were different hardness but that was not the issue.  Turkish Wave Agate  Montana Agate, I had the pleasure of seeing it turn into an Iris Agate as I cut and polished. The greenish hue is from the iris effect. I am trying to figure out how to get a picture that really shows the effect, it is harder than one might think. |

Looking good! I hope you can photograph that iris effect. Lucky you!

I caught a shot that shows the rainbow effect, but wow is it tough to capture nicely.  |

I see it on the bottom of the cab. I've cut a lot of MT aggies, but never had any iris.

I know, I feel so lucky to have gotten one, I think the slab, basically a cab's worth, set me back a dollar. The colors started showing up around the 4th wheel. Though it is crystal clear in between the black, most of the time there is a small amount of color playing there. Gives it a more milky appearance in photos than the actual, though you don't really see the color in most shots. |

I wonder if you hold it (or prop it up) so you can see sunlight coming through it and take the picture that way, if that would help should the iris. |

Should also try a shot to show how clear the stone actually is. |

I have picked up quite a few and have some tumbling now, but I never new they could have such color effects coming out! That one looks cool even without that little plus. |

This effect is why you often see montana agates cut much thinner than other slabs, more likely to get the effect, also the stone must be polished to a degree to see the effect. I am guessing that you have to get lucky on the orientation also. Other agates can show the same effect, Brazilian agates and similar agates from Indonesia are ones that I know of. |

I will have to try slicing some of the clearer Montana agates thin and keep my fingers crossed to see if I make some color magic! Either way, they are beautiful rocks. |

Also look for turtle back patterns in them when you're slicing them thinner.

I'd be ecstatic to come across colors like that! |
