Unusually striking, rhodolite is a naturally occurring blend of almandite and pyrope garnet. While raspberry is the most prized color, rhodolite is also found in shades of pink through lavender, including the ruddy purples of its namesake, the rhododendron flower. Rhodolite is typically found as water-worn pebbles in alluvial deposits, but it is also occasionally mined directly from host metamorphic rock. Tough, durable, never enhanced and easily cleaned, rhodolite is ideal for jewelry. Due to its bright transparent clarity, rhodolite is often cut into fantasy shapes.
