Way to verify which Unusual Gems that I already have

the-elder-scrolls-v-skyrim

I have one less Unusual Gem than I expect and I don't want to go through the tedium of revisiting each location. http://www.uesp.net/wiki/Skyrim:No_Stone_Unturned#Finding_the_Gems lists each Unusual Gem's RefID, so it would seem the task is to check the RefID of each of my Unusual Gems.

How do I do check the RefIDs of my Unusual Gems? Or is there an easier way to check?
 

I tried "drop 7f956", but I get an error:

Invalid inventory object '7f956' for parameter ObjectID.

I also tried the second RefID, adding the player. prefix, adding 1 (quantity) after the RefID, making sure there was no RefID highlighted in console, and enclosing the RefID in quotation marks.

In terms of mods, there's Stones of Barenziah Quest Markers (and Stones of Barenziah DROPPABLE plus Quest Markers). Once it's activated, check the world map.
