Product sources: The ITTO reports that timber production from this species is regular. The material is exported at a low but regular rate. Supplies are ample, but the wood is fairly expensive. It costs more than mahogany but less than teak. Although it has not found wide demand, Purpleheart is available on the US market in both the lumber and veneer forms.

Environment profile: Vulnerable

Tree size: Trunk diameter is 200-250 cm

Colors: the heart isRed, Yellowand the sapwoodWhite to yellow, Yellow.The grain isStriped figure, the textureMediumand the lusterPronounced

Natural durability: Very durable, Very resistant to dry-wood termite attack

Odor: No specific smell or taste

Kiln Schedules: UK=E US=T6D2/T3D1 Fr=5

Kiln Drying Rate: Slow

Drying Defects: Slight surface checking, Slight twist/warp

Ease of Drying: Variable results.

Tree Identification: Bole/stem form is buttressed

Comments: General finishing qualities are rated as good Treatment against the effects of ultra-violet rays has been suggested to maintain the original color of the wood. A treatment with Armorall, the car finish product, under lacquer is reported to hold the color wellWorking the wood with dull cutting tools may cause gum exudation
