I just checked book that I have " The Jeweler's Directory of Gemstones" and there is just too much red and even pale color Hessonite garnets have reddish hue in them...
Having said that, the only garnet stone that can raise good argument against Citrine stone is 'Mandarin garnet'...and the book says, "this Mandarin garnet is from Namibia and it has the most fantastic bright orange color. Gem-quality mandarin garnet is VERY RARE and valuable.
In addition, some Citrine stones have bright orange colors too...even though they have more yellow hues in it..look and compare
There is no doubt in my mind that CPMaxima's and QBeatrix's jewels are in fact Citrine....
all the photos were taken in daylight so you can see stone colors clearer you be the final judge
