Rhodolite

Rhodolite is a varietal name for rose-pink to red mineral pyrope, a species in the garnet group.

[2] The name is derived from the Greek "rhodon" for "rose-like", in common with other pink mineral types (such as rhodochrosite, rhodonite).

[3][4] Rhodolite garnets appear as transparent red-pink-purplish gemstones, including all the different colour shades between violet and red.

[citation needed] Some rhodolites will change color from purplish to a hessonite brown when heated to a temperature of 600 °C (1,100 °F).

Other sources of rhodolites are in Brazil, India (Odisha), Norway, United States and Sri Lanka.
