All burls imported and sold here at AustralianBurls.com are among the more than 700 species of the diverse genus of Eucalyptus. When customers who've not worked with these burls ask if they are hard, I often reply - only half jokingly - that there are only 2 species of burls among Australian Eucalyptus . . . hard and harder. The simple beauty, range of color and figure are truly spectacular. Given that, and their price relative to other popular exotic burls like Amboyna, Cocobolo and Rosewood Burl, you'll find Australian Burls hard to beat.
