    These are the berries of Pollia condensata, a wild plant that grows in the forests of some African countries. It is a metallic fruit which stay a vibrant blue for years or even decades after being picked. Scientists have discovered that the fruit uses nanoscale-sized structures to produce the most intense color ever studied in biological tissue, and have just named them the world's shiniest natural object after tests revealed they reflect nearly 30% of light.

    The world’s most intense natural color comes from an African fruit, the blue berries of Pollia condensata, a wild plant that grows in East Africa. It uses an uncommon structural coloration method to produce the most intense natural color ever measured. Instead of pigments, the fruit’s brilliant blue results from nanoscale-size cellulose strands layered in twisting shapes, which which interact with each other to scatter light in all directions.
