It's a Wand of Enlarge Person. Period. Wands aren't really specific about class or even arcane/divine boundaries.
Pathfinder Core Rulebook, Magic Items, Spell Trigger Iterms wrote:
Spell trigger items can be used by anyone whose class can cast the corresponding spell.
So the sorcerer can use this wand because his class is capable of casting Enlarge Person (the fact that the creator used divine magic to create the wand doesn't come into question for spell trigger items). The cleric could only use it if he had class features giving him access to the spell; otherwise his class cannot cast Enlarge Person so he cannot use it.
