Things you should know:

You can only get five Iridescent Ore Fragments and one Iridescent Ore per character per week. Resets with the normal weekly reset.
You can only get a certain amount of Iridescent Ore Fragments, and the remaining number you can still get for the week can be seen in the profession window when selecting this entry (just called Iridescent Ore) under the section called Appendix I - Boundless Knowledge, it will show as the last line of text on the right. Resets with the normal weekly reset.
All nodes can drop the Iridescent Ore Fragments, including elemental nodes, Titan-touched and Infuriated nodes.
Iridescent Ore is essentially the last Iridescent Ore Fragments you can get for the week. So when you get the Iridescent Ore, that means you will no longer get any Iridescent Ore Fragments or Iridescent Ore on this character for this week.
Primal nodes drop the Elementally Charged Stone.
Molten nodes drop the Heated Ore Sample.
Hardened nodes drop the Unyielding Stone Chunk.
There appears to be no weekly limit on Elementally Charged Stone, Heated Ore Sample or Unyielding Stone Chunk, though they have a significantly smaller drop chance compared to Iridescent Ore Fragments and likely do not drop from Titan-Touched, Infuriated, Rich and normal nodes.
Elementally Charged Stone, Heated Ore Sample and Unyielding Stone Chunk all seem to share the same journal entry in the profession window, that being the entry for Elementally Charged Stone.

What do you mean? I can't find anything, maybe add a screenshot?

Hello everyone!
Just like stated by EternalWulf, you can check in your tooltip for Iridescent Ore Fragments how many you can still gather per week.
However if you would like to have a look for yourself via scripts here they are, along with the Draconic Treatise on Mining

/script print(C_QuestLog.IsQuestFlaggedCompleted(72160))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72161))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72162))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72163))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72164))

Iridescent Ore being the last one you can gather for the week.
/script print(C_QuestLog.IsQuestFlaggedCompleted(72165))

Draconic Treatise on Mining
/script print(C_QuestLog.IsQuestFlaggedCompleted(74106))

As of this post I have maxed mining and am still getting the ore fragments. I now have 2 knowledge points that I cannot spend on any specializations.

EDIT UPDATE: You can now trade the extra knowledge for Artisan's Mettle with Apprentice Crafter or Apprentice Gatherer, who are standing about 20 yards east of the stairs leading up to the crafting orders platform at 37.34, 64.72 in Valdrakken. 10 knowledge for 25 mettle.

An all-in-one macro to check if the following items have been completed for the week:

Draconic Treatise on Mining x1
Iridescent Ore Fragments x5
Iridescent Ore x1
/run local t={"Crafted",74106,"Blue 1",72160,"Blue 2",72161,"Blue 3",72162,"Blue 4",72163,"Blue 5",72164,"Purple",72165}for i=1,#t-1,2 do print(t,C_QuestLog.IsQuestFlaggedCompleted(t)and "\124cff00ff00Yes" or "\124cffff0000No")end

Items with no weekly limit are the following:

Elementally Charged Stone
Unyielding Stone Chunk
Heated Ore Sample
