This one has rich coloration, One can clearly see the stone's unmistakeable one-of-a-kind pattern of flower-like starbursts. Hence the name 'flowers of the sea', as it is sometimes known. The stone is actually composed of the highly silicated fossil remains of colonial sea coral, many millions of years old! 58x24mm/56 carats
