Which 2 trinkets should I use here as a holy priest?

[Nanaboostme]

I'm not a 100% sure which two I should choose but I own the 3 following trinkets, all ilevel 359.

Vibrant Alchemist Stone
+301 Int
Red Socket - Socket Bonus +10 Int
+Haste 194
+40% Healing/Mana Potions

Core of Ripeness
+321 Int
Use: Increases your Spirit by 1926 for 20 sec. (2 mn CD)

Fall of Mortality
+321 Int
Equip: Your healing spells have a chance to grant 1926 Spirit for 15 sec.

I also own Soul Casket, which has +321 Mastery and a Use: Mastery 1926 for 20 sec, but I'm certain it wouldnt be priority if I'm correct.

Go with Core and Fall, both are much better then Alch stone.
