Pilea mojito...A very rarely offered variegated Pilea also known as the Chinese money plant or lucky plant.  These are really stunning lime/minty green variegation. Very litmed number. Would recommend a heat pack to keep him snug.
 Heat pack suggested 
 
Care: Bright to indirect light a bright spot on a window seal would be ideal at this time of the year but watch out for draughts and heating. I water my Pilea every 7 to 10 days, but your home’s conditions may mean the plant requires more or less frequent waterings. Another good tip it to water when the pot feels light. 
 
Extra information:
Size: Pot Diameter 14cm Height appx- 27-30cm 
Toxicity: Considered non-toxic to humans and pets.
Difficulty: Can be a little fussy
Air-purifying: Yes
Feeding: General, the majority of houseplants should be fed every 2nd watering during the growing season (Spring and Summer), for me, it's about which every 14 days. In autumn and winter, I feed less, as indoor plants will require fewer nutrients.
