Gem gravels, Ratnapura, Ratnapura District, Sabaragamuwa Province, Sri Lanka

A natural, uncut, lavender-colored sapphire crystal from the gem gravels of Sri Lanka, smoothed from water (but with faces still evident) exactly as they are found in this prime source of sapphires for the world market. Great specimen for the collector.
