The Diya lamp is an Indian thing, we use it for rituals and festivals for example. The one shown in the emoji is an earthenware one, which are the "original", but somewhat messy to take care of, especially if you don't have a single fixed permanent location for them. There are many metal equivalents though, usually brass, that are easier to handle and clean.
