Grape agate

not a review, Article appears to be misnamed, per MINDAT and our article "Agate is concentrically banded chacedonly". This botryoidal chalcedony is not agate. Additionally what is a veracity as a WP:RS given the origins of much of the site though wiki-style input?--Kevmin § 17:05, 19 March 2026 (UTC)

Grape agate is the WP:COMMONNAME; more appropriate mineralogical names are discussed in the article. (Also, this is actually botryoidal quartz/amethyst, not chalcedony). As for mindat.org, my understanding is not just anyone can add information there; there is some level of editorial oversight. Questioning it as a WP:RS would be a big problem, since it is used significantly in almost every single mineral article on Wikipedia (there are about 2000), including at least a few GAs and the FA Diamond).

Per this journal article: "A team of about 100 mineralogical experts volunteer as data curators to review and cleanse the records and photos with input from other members. Unlike the Wikipedia system where anonymous edits are possible, all contributions must be approved by registered users and are peer-reviewed by regional experts."

Just noting that mindat.org is not the source for this hook anyway. I₂Overcome ^talk 00:54, 20 March 2026 (UTC)

Overall: A very easy review; no issues. I agree that the article should be at the common name. Beautiful image, a Featured Picture on Commons. The hook is more descriptive than surprising, but, well, it's a mineral, we're not going to get emotional tugging at the heartstrings. The sources are all scientific and consistent with each other.

Introduction

Hello, I am writing just to introduce myself and let you know that I am going to review this article. On first read, this is a concise, well-sourced article so I expect to complete my review in the coming few hours and will edit/update when I have done so. Thanks!

Review

Edit: I have finished my review. In short, this article rocks. Decision: Pass. Congratulations!

This article clearly meets the GA criteria. It is well-written (readable, no typos), structured well, appropriately sourced (including a number of academic sources; earwig gives no copyright issues), reasonably comprehensive (but see my 2 notes about potential opportunities for expansion), and stable. There are 5 images with free licenses.

Optional Polish

• Regional Geology - and Utah? I am not a geologist, but I found myself wondering why this particular rock is only found in Sulawesi Island, and after googling around, found that Grape Agate can also be found in Utah!? (source and also source) That's a very strange geographic reach (again, not a geologist but an island of Indonesia and Utah seem quite different to me). A sentence or two about where this rock can be found and why might make for nice additions. Oh, and it seems that the Utah rock might be a different color?
• Commerce. Perhaps the author could add a sentence or two expounding on the scale and shape of the sale of grape agate. The article mentions dealers and online marketplaces, and from googling, it is clear that there is commerce in this rock. The article doesn't give a sense of the scale of the market, which is potentially noteworthy information if high quality sources exist. To the earlier point (Utah), the impression I get is that the Indonesian purple stuff is what's commercially valuable, whereas the more orange Utah stuff is not (just my cursory googling, not actually verified).
• The author could consider adding alt= tags to the images for accessibility.

Thanks for your contribution and congratulations again! Mnation2 (talk) 01:15, 24 May 2026 (UTC)
