An '''emerald''' is a [[mineral]] [[gemstone]] and a variety of [[beryl]]. It is the birthstone of someone whose birthday is in the month of [[May]]. It is a [[green]] crystal. The emerald is one of the most valuable [[gem]]s, along with the [[ruby]], the [[opal]], [[topaz]], the [[diamond]], and a [[sapphire]].

== Etymology ==

The word ''emerald'' comes from [[Vulgar Latin]]. The word was Esmaralda/Esmaraldus, a different way of saying the Latin word ''Smaragdus'', which came from the [[Greek language|Greek]], {{lang|el|σμάραγδος}} (''smaragdos''; "green gem").<ref name=Fernie/><ref name=etymology>{{Cite web

It is where the [[Persian language|Persian]] ({{lang|fa|زمرّد}} ''zomorrod''), [[Turkish language|Turkish]] ({{lang|tr|zümrüt}}), Sanskrit ({{lang|sa|मरग्दम्}} ''maragdam'') and [[Russian language|Russian]] ({{lang|ru|изумруд}}; ''izumrúd'') words came from.<ref name=etymology/>
