Bryson Bobelu's gorgeous bird sings out with pure joy. Carved from creamy green Archean butterstone with beautiful iridescent wings of pretty, pink mussel shell and bright eyes of inlaid turquoise. This happy little bird measures about 2 1/2" tall and 2 deep. Archean butterstone was formed during the Archean Eon, 4000 to 2500 million years ago. In this time, the Earth's crust had cooled enough for continents to form and for the earliest known life to start.
