Make your object a pale white (190-ish on all the RGB sliders), high Shiny value, high Hardness, low Roughness, Specular just a few shades below the object color, ummm, possibly others as well.
Apply two wood textures. The textures are rotated with respect to each other. Both have very wide bands (and a low number of bands) and a large Variation value (for "burl" effect, according to Understanding Imagine). The color of each texture is a darker shade of grey than the object, and the two textures have slightly different colors.
