Gemmological properties

Rhodolite garnets are members of the pyrope-almandine solid-solution series.
Rhodolite garnets can have varying colors, ranging from lavender pink to raspberry red.
The brilliance, durability, and lack of visible inclusions make rhodolites desirable in the jewelry industry.
Rhodolite garnets are commonly faceted to enhance their brilliance.
Heating rhodolites to 600°C (1,100°F) can cause them to change color to a hessonite brown permanently.
