the REST of the pictures on this page will give you a better overall feel for this wood
Brazilian rosewood / Dalbergia nigra
4" x 4" flat cut, 4" x 4" quartersawn, 1" wide end grain, and a 1/4" x 1/4" end grain closeup.
Diffuse porous with large, sparse, randomly spaced pores, with fairly thick vasicentric parenchyma (which can appear aliform on rare occasions), occasional radial pore multiples, rays barely visible at 10X. There is plentiful banded parenchyma that is sometimes very clear at 10X, sometimes hard to see and likewise for diffuse-in-aggregates parenchyma. Plentiful pore multiples. Growth rings are indistinct.
NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K)
colors will vary under other lighting conditions
