How to tell if gelato is authentic?

Could you please elaborate on the process of identifying authentic gelato? I'm particularly interested in knowing if there are any specific ingredients, flavors, or textures that set apart the real deal from imitation gelato. Additionally, are there any telltale signs that consumers should look out for when making a purchase? I'd also appreciate any tips or tricks that you may have for distinguishing between high-quality gelato and its lesser counterparts. Thank you in advance for your insights.
