Types of Trees:

The geographical range of these extraordinary trees extends from the upper Midwest United States into Canada and Alaska. While there are various tree species that can produce diamonds, including willows and the elusive “Iron Wood,” it is important to note that none of these trees are actually called “black diamond willow.” The specific tree responsible for producing these enchanting diamonds is known as the “Bebb Willow.”

Characteristics of Bebb Willow:

Bebb Willow, a shrub-like tree, reaches heights of around 10 to 15 feet and tends to grow in clusters. During the summer, its vibrant lime green leaves create a picturesque sight. This tree thrives in West Central Minnesota, particularly in areas near swamps, streams, rivers, and lakes—landscapes shaped by the remnants of the last glacier that existed 10,000 to 12,000 years ago. Surrounding vegetation, such as cattails and dogwood, often accompanies the Bebb Willow in these regions.

The Process of Diamond Formation:

The diamonds found in Black Diamond Willow are created through a fascinating process. In springtime, beetles chew their way through the bark of the willow tree, primarily near branch origins, creating burrowing holes and tunnels as they feed or lay their eggs. Eventually, the beetles depart, leaving behind a fungus known as Valsa Sordida Nitscke. This fungus triggers an infection response in the tree. In an effort to ensure its survival, the tree isolates or encapsulates the infection, initiating the formation of a diamond. Each year, the diamond grows with the expansion of annual rings. As the outer edges of the diamond continue to perish, the tree reinforces its protection by growing an even larger diamond.

Tree Anatomy and Diamond Colors:

Every tree possesses a core known as “Heartwood” and a living outer layer called “Summerwood.” The “Summerwood” acts as a conduit, transporting nourishment from the ground to the leaves, while the “Heartwood” provides strength and rigidity to the tree. Living “Summerwood” exhibits a light, cream color, while the dead “Heartwood” features a darker, chestnut hue. Since the diamonds formed in Black Diamond Willow share the characteristics of dead “Heartwood,” they have a chestnut color underneath their surface, accentuated by the black fungus pigment.

Utilization of Black Diamond Willow:

The hardness, density, lightness, and strength of the wood from these small willow trees make them highly desirable for various applications. Canes and walking sticks crafted from Black Diamond Willow branches have gained popularity for their elegance and functionality. Moreover, due to their resistance to water and rot, these trees were historically used as fence posts in areas adjoining swamps and wetlands, offering a natural alternative before the advent of steel and green-treated wood posts. Additionally, Black Diamond Willow played a unique role in the lives of pirates, soldiers, warriors, and individuals who had lost limbs. They often fashioned artificial peg legs from these trees, appreciating the lightweight and robust qualities of the wood. The presence of natural diamonds within the prosthesis added a distinct charm, initiating countless intriguing conversations and connections along their paths.
