message: Apparently the magnetic toys, sold under names such as 'oidz', 'uberorbs' and others, are made of hematite, was gonna add a few words about this into the pop culture section but could only find the following reference on play.com and wasnt sure if it counts as a real reference or not (yes im a n00b, no biting plz): http://www.play.com/Gadgets/Gadgets/4-/852389/Oidz/Product.html. I'll add the bit to the article in a few days if no-one objects or offers and advice etc Pledger166 02:39, 16 January 2007 (UTC)
replies: text: A sales pitch by a commercial adv site is hardly a valid reference. Hematite is not a metal as the site states, but an iron oxide mineral with limited magnetic properties. Vsmith 01:32, 17 January 2007 (UTC)
replies: text: I agree that the reference is rubbish that's why i queried the fact in here first, i wont claim to know too much about hematite, thats how i looked at this page in the first place, however there does seem to be a vast amount of mentions to these toys being made from hematite, simply type hematite and oidz into google and u'll get more than a thousand hits, there also seems to be a fair bit more info suggesting the magnetic proporties of hematite, as previously suggested by some one else at the top of this page, if anyone knows more about this, information would be gladly recieved.

replies: text: It's too late to ask the 6th grader whether they really wanted to know what kinds of rocks hematite is found in; but this article could certainly use more on its natural occurrence. I don't think we could do much to make this article accessible to grade 6 students, though. RockMagnetist(talk) 20:11, 11 July 2016 (UTC)

message: Why does this article use the "." to separate the thousands group in "80.000" years when the decimal point is also used for radix point in items like "Specific gravity 	4.9 - 5.3"

thread_title:  Radix point usage. 

message: This article has lots of shiny metalic images (particularly the jewelry), which look like sections of polished metalic (fairly pure) iron. Does polishing (or some other treatment) reduce the surface layer to metalic iron? Or does the oxide itself have a grey metallic allotrope? Or perhaps cynically (but with relevance to the accuracy of the article), does hematite jewelry refer simply to jewelry made from the lumps of metallic iron that can be commonly found amongst rocks that are otherwise mostly composed of hematite? Cesiumfrog (talk) 02:26, 4 March 2012 (UTC)
replies: text: Err... only see one "shiny" image, the bear. The color varies as the article notes and shiny gray "specular" hematite is one variety. "Lumps of metallic iron" would be very unusual with hematite as a quite different redox environment is required. Am quite skeptical of "hematite" jewelry ... but don't know much about such. Vsmith (talk) 03:18, 4 March 2012 (UTC)
replies: text: An abstract note: both the refractive index and absorption are high for hematite in the visible range, meaning its smooth surfaces must be shiny without a need for metallic iron. Materialscientist (talk) 03:26, 4 March 2012 (UTC)
