Caesalpinia paraguariensis of the family Fabaceae (syn Leguminosae) the legume, pea, or bean family
NOTE: the name guayacan / guyacan is used for over 70 species from at least 30 genera, but in the USA it USUALLY means Caesalpinia paraguariensis and is actually listed most often with the common name Argentine brown ebony or (less often) Argentine ebony or brown ebony, rather than, or in addition to, guayacan. It is my intent that this page be for that wood, but I may put in other species of "guayacan" if I run across them.
my samples: NOTE: these pics were all taken in very bright incandescent lighting --- colors will vary under other lighting conditions

bowl by Bryan Nelson (NelsonWood). Bryan fine-polishes his bowls with 1200 or even higher grit sandpaper while they are spinning at high speed on the lathe and then finishes them there with a friction polish of his own devising, thus achieving a shine and color vibrancy that is beautiful to behold. Really big enlargements are present.
bowl --- I assume the green color of the sapwood is poor photography, not an actual wood color.
pen turned from guayacan / Caesalpinia paraguariensis. Photograph contributed to the site by the pen turner, Bruce Selyem, whom I thank for this and other contributions to the site. The pen is finished with shellwax. Clearly this is half heartwood, half sapwood.
