the REST of the pictures on this page will give you a better overall feel for this wood
goncalo alves / Astronium spp.
5" x 5" flat cut, 3" x 3" quartersawn, 1" wide end grain, and a 1/4" x 1/4" end grain closeup.
Diffuse porous with moderately large, moderately sparse pores with vasicentric parenchyma, occasional pore multiples, and growth ring boundaries that range from somewhat clear to quite vague. Rays are present and usually visible at 10X but not to the naked eye. Obvious amorphous dark streaks throughout the heartwood are common.
The flooring industry calls this wood by the marketing name of "Patagonian rosewood", which is consistent with their total indifference to reality given that this wood is not a rosewood and it does not grow in Patagonia.
NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K)
colors will vary under other lighting conditions
