Buzzing Crystal??
http://wiki.guildwars2.com/wiki/Windrock_Maze according to the wiki.
The two zones you mentioned are too high level.
Thanks Khisanth, got the Crystal after killing six sparks, spend an hour killing them yesterday in different places!
I used this link and it shows the areas where I was hunting.
http://wiki.guildwars2.com/wiki/Buzzing_Crystal (unhide) lists the areas to find them

The problem is the wiki drop lists don’t discriminate between levels. It knows the mob drops it, but not at which level, so it will just list everywhere the mobs are and let you figure it out yourself.
I had a hard time with this one as well. I eventually found this page:
http://wiki.guildwars2.com/wiki/Spark_
under Drops, it has:
Junk
Buzzing Crystal – level 3-19
Charged Crystal – level 37
Shocking Crystal – level 79
going back up the page, we have these areas:
Maguuma Jungle / Metrica Province / The Hinterlabs – level 3
Ascalon / Plains of Ashford / Windrock Maze – Level 14
Shiverpeak Mountains / Snowden Drifts / King Jalis’s Refuge – Level 19
personally, I tried all 3, but wasn’t having much luck, so I stayed at Windrock until I got one; It has the largest amount of sparks, so I figured the highest availability to get one.
Personally, I had a harder time finding the Charged Crystal (until I found that page I liked above).
long story short, the only spot on the entire map to find an enemy that drops it is at Harathi Hinterlands / Splintered Teeth / Restricted Zone XRB poi (just outside the cave). There are like 5 sparks, took me about 20 min before I got a charged crystal.
omg, if only we saw this earlier:
http://wiki.guildwars2.com/wiki/Trash_Collector
it actually has a ‘Convenient location’ for the best spot to find enemies that drop all of those.
