Urchin Quartz

Urchin quartz (quartz with Mannardite crystals) should probably be included here because it is quartz. I don't know anything about quartz though. Mr moothedisastercat neo (talk) 15:30, 13 December 2022 (UTC)[reply]

I wouldn't put it in the list of "Major Types" as it is rare, but we could put a picture in as it is very interesting.

Most-common mineral

The first paragraph states that "Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar." However, feldspar is not a mineral. It is a group of minerals, so comparing it to a single mineral like quartz is misleading. A more apt comparison would be silicate minerals to feldspars, or quartz to a specific feldspar like albite. As it is, this is a bit like saying "Ants are the second most abundant species on earth, behind vertibrates."— Preceding unsigned comment added by 128.119.119.11 (talk) 19:02, 11 June 2024 (UTC)

Page for Citrine?

As far as I can tell, citrine is the only major quartz variety that doesn’t have its own Wikipedia page. Could someone who has the ability to do so create one? I2Overcome (talk) 04:32, 21 January 2025 (UTC)[reply]

The blue links do not all go to a Page- Rose quartz also doesn't have one. I'm no expert, but I will see what I can do about both of them. If you would like to help, get back to me on my page.

I created the page for citrine several weeks ago when I realized I could do it myself. Sorry for not updating this comment thread. The links for citrine in this article should now go to the new article, Citrine (quartz). There are still no articles for rose quartz or milky quartz, which are still redirects to Quartz. I may eventually try to create pages for both, but there is arguably less to say about them (especially milky quartz). Of course, you are welcome to create them as well. —I₂Overcome ^talk 03:39, 11 March 2025 (UTC)[reply]

Herkimer - Major type ?

The list of types is described as the Major Types of quartz, but the Herkimer Diamond page itself says that only those crystals that come from Herkimer County should be called that. It isn't even really a different type of quartz, its just quartz formed double-ended and that can happen to any quartz, anywhere. I'm minded to remove it and maybe insert a reference to it elsewhere, under a name applicable to this formation anywhere. IceDragon64 (talk) 01:47, 11 March 2025 (UTC)[reply]

I would be in favor of just removing "major" from the title of the table. There are a few other varieties on that list that are not really "major" varieties of quartz, like Dumortierite quartz (which doesn't have its own article) and Rutilated quartz. However, Herkimer diamond is at least notable enough to have its own article, and this is its only mention in this article (besides a photo caption).

I agree that the table title should be renamed from "Major varieties of quartz" to "Varieties of quartz". GeoWriter (talk) 19:31, 11 March 2025 (UTC)[reply]
