Answer

Rarity is correct and yes it's a noun used to identify something which is rare.
Primarily used for historical artefacts or collectibles but sometimes also things like animals or plants. 
Eg on seeing a rare bird, someone might say That's a rarity in this country, usually this species stays further south.
