Amboyna is among the most expensive and sought-after of all burls, and is frequently sold as veneer or as small turning/craft blanks. Some suppliers specify “Red Amboyna” for material with the typical rich reddish-brown heartwood, or “Golden Amboyna” for pieces with lighter yellowish brown coloration. It’s not unusual for pieces to contain sharply contrasting yellowish sapwood. Aside from Chessboards, Amboyna is commonly used for fine furniture, boat building, turned objects, electric guitar tops, knife/gun grips, and other small specialty wood items. High-grade Ambyona burl ranks as one of the most expensive woods in the world. For more technical information on Amboyna, visit http://www.wood-database.com/amboyna/.

A burl (American English) or bur or burr (UK English) is a tree growth in which the grain has grown in a deformed manner. It is commonly found in the form of a rounded outgrowth on a tree trunk or branch that is filled with small knots from dormant buds. A burl results from a tree undergoing some form of stress. It may be caused by an injury, virus or fungus. Most burls grow beneath the ground, attached to the roots as a type of malignancy that is generally not discovered until the tree dies or falls over. Such burls sometimes appear as groups of bulbous protrusions connected by a system of rope-like roots. Insect infestation and certain types of mold infestation are the most common causes of this condition. Maple Burl is not a distinct species of Maple, but rather, it’s a figure that’s occasionally found in Acer saccharum (Sugar Maple) trees.
