has anyone else noticed their ability to HQ go down lately?

It could just be my terrible luck or something but when i was level 39 I went through all the quartz i had in an attempt to get HQ gems and was able to succeed about 30% of the time, now at level 44 goldsmith I attempted to do the same thing and instead of getting a better HQ rate I actually was unable to HQ even one gem out of 20 during full moon even though every gem had a quality of over 200
