Color/Appearance:When freshly cut the heartwood of Purpleheart is a dull greyish/purplish brown. Upon exposure the wood becomes a deeper eggplant purple. With further age and exposure to UV light, the wood becomes a dark brown with a hint of purple. This color-shift can be slowed and minimized by using a UV inhibiting finish on the wood.
Grain/Texture: The grain is usually straight, but can also be wavy or irregular. Has a medium texture with good natural luster.
Endgrain: Diffuse-porous; medium to large pores, few; solitary and radial multiples; mineral deposits occasionally present; growth rings may be either distinct or indistinct depending on species and growing conditions; medium ray barely visible without lens, normal spacing.
Rot Resistance: Purpleheart is rated as being very durable, and resists both decay and most insect attacks, though it has been reported to be susceptible to attack from marine borers.
Odor: Varies depending upon the species: most species have no characteristic odor, though some species can have a pungent scent.
