The image is wonderful but I am wondering how to tell moss agate from tree agate.  What is the difference?  Boris B 04:58, 21 July 2007 (UTC)

Wikipedia needs to get hold of a different photo of "polished agates of various colors". At least half of the agates shown in the current version of that photo are of various colors because they've been dyed -- and blatantly, too. It's like illustrating a discussion of different types and textures of human hair with a photo of rainbow-colored dynel wigs.  —Preceding unsigned comment added by 69.203.146.16 (talk) 06:00, 29 December 2008 (UTC) 

Removed it - the image page states they were dyed. Don't need phoney pics. Vsmith (talk) 14:24, 29 December 2008 (UTC)

I notice that text on formation is lifted from the Encyclopedia Brittanica of 1910. Perhaps a SME could review the geology portion for accuracy  —Preceding unsigned comment added by Freesesj (talk • contribs) 15:28, 27 November 2010 (UTC) 

I've removed the recently added 3d gallery of agate slabs. I don't see the need for more images, especially in 3d of polished slabs. If we need 3d it surely would be for something with "depth" rather than a flat slab. Vsmith (talk) 23:43, 1 March 2012 (UTC)
if you can see the 3D you will see that we can see inside the rock, because it's a slab it permits light to go through well. To see the 3D you need to cross your eyes till you see 3 images, and than you need to focus on the middle image. Ronveron

"Polyhedroid" agate is a term commonly used on the Internet to describe a crystal which has grown with many flat sides or faces and which shows a distinct pattern of concentric polygons when cut across. I don't know whether it is an "official" description or just a popular one, but either way it appears common enough to need mentioning. Can someone add something appropriate to the article? — Cheers, Steelpillow (Talk) 13:16, 26 December 2014 (UTC)

Seems to be just a "sales pitch" term by rock & gem sales sites. Doubtful that a WP:reliable source exists - let me know if you find one. Vsmith (talk) 21:22, 26 December 2014 (UTC)
Thank you for your reply. Google found some RS for me :-) so I added it to the article myself. I couldn't check the citations directly, but I found them on the University of Nebraska-Lincoln web site (which I added to the External links), so I hope that's OK. — Cheers, Steelpillow (Talk) 11:28, 27 December 2014 (UTC)

Hi,
I've come across the following kinds/types of Agate & would like to inquire WHY they are NOT mentioned in this Wikepedia's entry: Crazy Lace agate; Brown Lace agate; Pink lace agate (aka: Aragonite), Botswana agate; Tube agate. Dragon Veins jasper, Turritella agate, Dendritic/Scenic Dendritic agate, Agua Nueva agate, Montana agate, Mexican Fire agate, Plume agate, Polka Dot agate, Passion agate, Scenic agate, Crab agate, Tree agate; —  Preceding unsigned comment added by AK63 (talk • contribs) 04:13, 3 July 2015 (UTC) 11

Same as on talk:jasper, WP:reliable source needed to verify the significance of these rock shop commercial names. Vsmith (talk) 02:38, 4 July 2015 (UTC)

There is a move discussion in progress on Talk:Agate Studio which affects this page. Please participate on that page and not in this talk page section. Thank you.  —RMCD bot 06:33, 19 July 2018 (UTC)
The article is well organized and the sections flow nicely. Each section is straight to the point and has great supporting references.  — Preceding unsigned comment added by ZeinabFashwal (talk • contribs) 04:28, 29 February 2020 (UTC)
