Honey locust is native to central North America but these branches come from a big tree, probably the cultivar of Sunburst, growing in the Czech Republic. There are typical clusters of thorns on the trunk and branches. On of the genera is Acacia that is why I took a photo of both kinds of wood together. It may make a nice combination of orange and green colour. The diameter is 33 cm, which makes an ideal size for a bowl.
