Citrine is a yellowish-orange mineral. Citrine is a very popular gemstone because it is very affordable and very pretty.

These elements can be found on the periodic table. The chemical formula of citrine is SiO2, which is silicon and oxygen (www.galleries.com).According to Webster's Dictionary, a silicate mineral is a combination of silicon, oxygen, and one or more minerals.
