European walnut (Juglans regia) grows in nearly whole middle- and southeast Europe, although beautiful figured walnut is a rather scarce wood: only about 5-10 percent of the mature trees have the typical dark brown heartwood with black streaks, that is priced very high- often as high as exotic tropical woods.
Caucasian walnut burl wood varies from greyish to dark chocolate brown colour with swirls, almost black dark wavy streaks form an impressive figure. It polishes excellent. having high natural durability. Caucasian walnut has very limited availability. Walnut burl wood almost always has typical small imperfections such as bark ingrowths, pin knots, swirls, hairline cracks. These can be filled quickly and easily with thin super glue and a little sawdust.
