Rhodolite is a varietal name for rose-pink to red mineral pyrope, a species in the garnet group. The name is derived from the Greek for "rose-like", but rhodolite itself is not officially recognised as a mineralogical term. It is considered a semi-precious gemstone. Chemically, rhodolite is an iron-magnesium-aluminium silicate, part of the pyrope-almandine solid-solution series, with an approximate garnet composition of Py70Al30.
