What do you call these characters? Are they trolls, Gnomes, or dwarfs?

Anyways these are as cute as a button (if buttons were cute)! This cute little character is finished on all sides and is accompanied by genuine green Aventurine gemstones. It’s worth noting that while aventurine is treasured for its beauty and metaphysical properties, its use for healing and spiritual purposes is based on belief and should not replace professional medical or psychological advice.
