It could be in any mine. I suggest that you try the buried bones mine. I find rare gems there all the time.
Actually, this isn't true. Each mine has certain gems that can be found. The only place to find the Red Ruby Heart is the Muzzle Mouth Mine.
in the 2nd lobby
When you click the button "Start Mining" you will be taken to a screen with five different mines on it. Choose "Muzzle Mouth Mine". This is the only mine that has the Ruby Heart Gem, keep trying every day until you find it, because it may take some time. Good Luck!
You can usually find it in the Howling Horse Mine. If you go to that mine, the backround will be blue and the gem is blue. So that's a way to remember where you can find gems. For more examples, I found my Red Heart Ruby in the Muzzling Mine gem. I found the Diamond in the Buried Bones Mine.Hope this helps!- ClubPenguinLuvr :)
