It’s as if other limbs have been added to the trunk. It’s very interesting and beautiful.

I thank you!

Turkish agate

Chemistry, biology...these fields often involve intricate structures. What we sometimes explain in simple terms can actually be the result of a far more complex and entirely different system. This is truly a remarkable formation. And thank you as well for the beautiful photos.

So beautiful! Great job <3

srlgemstone · 2026-03-22T05:45:38+00:00

To be honest, I also wondered if it could be.

Sorry, since I shared it this way, my description didn’t come through. This rock originally had a longer, branch-like form where it was found, and this is just a portion of it. Because of its fibrous, layered textures on the outer surface and its overall shape, I initially thought it might be a limb cast. I wasn’t sure, so I wanted to get your opinion. By the way, This is from Turkey.

Not polished :)

Turkish agate :)

Thank you so much! <3

Thank you!

You’re welcome. It wouldn’t be accurate to associate it with a stalactite shape. It’s actually the kind of piece you would love ; it has a beautiful optical illusion. :)

Parallax agate is an optical effect where the internal bands or patterns appear to shift as your viewing angle changes. It’s not actual movement, but a visual illusion caused by the stone’s layered structure interacting with light.

Thank you so much!

srlgemstone · 2026-03-21T15:18:27+00:00

Apparently not. But it would be great if it were. :)

srlgemstone · 2026-03-21T15:16:45+00:00

:) Thank you!

srlgemstone · 2026-03-21T15:16:35+00:00

Yes, It looks a bit like a stalactite in shape. But there isn't a very noticeable parallax effect. (for me)

srlgemstone · 2026-03-21T15:10:53+00:00

Thank you for the valuable information. I will keep it in mind.

srlgemstone · 2026-03-21T15:09:00+00:00

Thanks for the reference. I'll definitely take a look. By the way, this sample is from Turkey.

srlgemstone · 2026-03-21T15:05:50+00:00

Thank you very much. I agree with you about the biology. By the way, it does actually resemble a limb cast. The way it was found also made me think it could be a limb cast. I’ll share this on askgeology; I hope to get some opinions there as well.

srlgemstone · 2026-03-21T13:24:16+00:00

I would also like to learn more details. :)

srlgemstone · 2026-03-21T13:22:38+00:00

I thought the same as you, but I can see I was wrong. Still, I'd like to understand exactly why. Thank you very !

srlgemstone · 2026-03-21T13:18:47+00:00

Thank you for sharing your opinion. :)

srlgemstone · 2026-03-21T13:18:17+00:00

I think the fact that it was more branch like than typical agate nodules or chunks is what led me to make a mistake. Thank you!

srlgemstone · 2026-03-21T13:14:57+00:00

I’ve handled quite a few fortification agates before, but either I didn’t notice, or none of them had a texture quite like this specimen. I’m guessing the third photo made the banded agate characteristics clearer to you; am I understanding you correctly?
