|Color: Ranges from a light olive green to a darker greenish brown to almost black.**Despite the great color differences shown in the samples above, both woods have virtually the same color range, and could easily be confused with one another.||Color: Ranges from a light olive or yellowish green to a deep brownish green.*Despite the great color differences shown in the samples above, both woods have virtually the same color range, and could easily be confused with one another.|
|Average Weight: 84 lbs/ft3 (1,350 kg/m3)**The two weights are so close, and easily within overlapping range of one another from tree to tree, that weight is not a reliable means to distinguish these two species.||Average Weight: 81 lbs/ft3 (1,300 kg/m3)**The two weights are so close, and easily within overlapping range of one another from tree to tree, that weight is not a reliable means to distinguish these two species.|
|Scent: Lignum Vitae has a distinct, perfume-like fragrance that lingers even after it has been machined. (Though typically, the scent seems to be less potent in Genuine Lignum Vitae.)||Scent: Verawood/Argentine Lignum Vitae has a distinct, perfume-like fragrance that lingers even after it has been machined.|
Endgrain: Although the pores are very small and difficult to make out on both species, examining the endgrain pores is really one of the easiest and most reliable ways to separate these two woods. I suggest cleaning up the endgrain and possibly sanding it to a fine (400+) grit to help get a clear view of the pores and their arrangement. Using a 10x magnifying lens, you’ll notice two things about the pores of Genuine Lignum Vitae: they are almost all exclusively solitary, (that is, none of the pores are bunched together in groups or pairs), and they are arranged in a somewhat random pattern, or perhaps slightly diagonally. However, in the pores of Argentine Lignum Vitae, you’ll notice the pores are frequently arranged in clusters and radial (vertical) rows. This pore arrangement is a dead giveaway for Bulnesia spp.
Are you an aspiring wood nerd?
The poster, Worldwide Woods, Ranked by Hardness, should be required reading for anyone enrolled in the school of wood nerdery. I have amassed over 500 wood species on a single poster, arranged into eight major geographic regions, with each wood sorted and ranked according to its Janka hardness. Each wood has been meticulously documented and photographed, listed with its Janka hardness value (in lbf) and geographic and global hardness rankings. Consider this: the venerable Red Oak (Quercus rubra) sits at only #33 in North America and #278 worldwide for hardness! Aspiring wood nerds be advised: your syllabus may be calling for Worldwide Woods as part of your next assignment!
