By the way, you may want to check the main Monster Hunter World guide I am trying to complete here if you have time.
Author's Note: After the Kulve Taroth update (MHW ver 3.0 onwards), the drop rates changed as T1 can now also drop warped feystones, T2 can now drop hero streamstones and T3 will drop streamstones more often. I don't have formal information on the new rates but I will be updating this or creating a new write-up for it asap. This was to compensate for nerfing flashpods in the update. Bottom line is, hunt T3 for streamstone farming and T1 or T2 still for specific jewels. Table #3 is still usable as reference.
Feystone Appraisal (Table#1)

Decorations Drop Rates (Table#2)

Now, as for the drop rates of these feystones, threat level 1 monsters will have a 0% chance to drop Warped Feystones. The threat level 2 monsters will have a higher chance of dropping a Warped Feystone than Threat level 3 monsters which are the Elder Dragons. The advantage of hunting Elder Dragons though is that they have a higher chance of dropping Streamstones for augmentation. Despite this drop rate, proceed to Table#4 for the math on true % chance to get a jewel under certain categories.
Tempered Monsters Threat Level (Table#2.1)

Exceptions (no tempered version) - Great Jagras, Kulu-Ya-Ku, Tzitzi-Ya-Ku, Great Girros, Dodogama, Zorah Magdaros, Xeno'Jiiva
Decoration Categories (Table#3)
The table above shows under which category your desired jewel is (click to enlarge). So knowing the following data, refer to the first and second table on which Feystone to target and which tempered monster will have the highest chance to drop that specific Feystone.
How To Use the Tables:
1. Choose your target jewel on Table#3 and take not of the Category or Rarity.
2. Look at Table#4 for and take note of the Tempered Threat Level with the highest chance to yield a jewel under your desired category from step 1.
3. Hunt tempered monsters under that threat level from Table#2.1 and pray for the RNG to be generous to you.
Target Jewel is Attack. Table#3 shows Attack is under Category A.
Table#4 shows that Threat level 2 monsters has a 7.14% chance to get a Category A monster. This is because you need to factor in all the other Feystones that you can also receive and the chance to get a certain category. So the true % chance considering all these, specifically for an Attack jewel, based from the table below will be the 7.14% divided by 22 = 0.32% chance. Wow, that's too sad but don't give up fellas. Also, if you are going to base this on a specific feystone, say for example you got all Warped Feystones, each Warped Feystone will have an 18% chance to get a Category A jewel based from Table#1, dividing it by 22 which is the number of jewels in that category and you have 0.82% chance to get that one specific jewel from that group that you are hunting for.
Combined Percentages to Obtain Jewels per Tempered Threat Levels (Table#4)

Still there? All the math is making my head hurt. After a good talk with fellow reddit users, the 26% on the Warped Feystone is indeed misleading. I must admit we all got caught up on this and overreacted a bit. So I do apologize if I got you all even more excited. Tempered threat level 2 monsters will indeed have a higher chance to get Category A jewels. However the percentage chance is only slightly higher 7.14% > 6.66%. For me though, this is still significant and since this percentage is based per reward slot, here's the thing: if your tempered level 2 investigation has 4 reward slots versus a tempered level 3 investigation with 2-3 slots, it would make sense to go for the tempered level 2. There is another computation in which the chances are almost equal by Draycos on my reddit post here. Honestly, at this point I still stand with Threat Level 2 if I want that Category A jewel. In the end it will all come down to RNG and luck. There are still no guarantees but It is really hard to get exactly what you want so any increase in % to get that specific jewel, I think I'll gladly take it. I'd initially take the Feystone with the highest chance to yield my target jewel and worry about the other %'s later. Plus, threat level 2 monsters can be captured which can save you time compared to threat level 3 monsters which could also be more tedious and harder to take down. If I get a streamstone in the process then I'll thank the Sapphire Star for it. I'll save up the threat level 3 quests unless I find the need to go for streamstones. However, if you don't mind whatever jewel you get and want to leave it all to luck, then threat level 3 quests are the way to go as you have a higher chance of getting streamstones and still get the benefits of getting feystones in the process, thus having the most out of the hunting time you committed. As some people said and come to think of it, we are probably going to get burned out hunting threat level 3 all the time. It goes with what you prefer so there is still no right or wrong way of hunting just to make things clear.
Man, this is very useful and utterly frustrating at the same time. Ha ha. I want jewels such as Critical Boost and Attack Jewels only to find them on the highest categories. But at least now we all know what to do to have the highest chance of gaining the jewel we want. What is the rarest jewel you've obtained so far? Let's pray that the RNG will be nice to us. Hope this summary was helpful. Jewel-hunting we go! May the Sapphire Star light our way!
Some are suggesting a text format instead of images for the tables. I will work on that soon but blogger doesn't have a built-in table for easy formatting. I will have to do it manually using html which I do not have the luxury of time just yet. Anyway, fellow hunters have made spreadsheets for your convenience. I really screwed up the initial final %'s so I do apologize for that, the above percentages are more accurate.
For any corrections or if I ever had something wrong, please inform me by sending me an email or commenting below. Thank you!
