Material properties of diamond these are known as ballas and are important to industry as they lack the cleavage planes of single-crystal diamond. Carbonado is a similar opaque microcrystalline form which occurs in shapeless masses. Like ballas diamond, carbonado lacks cleavage planes and its specific gravity varies widely from 2.9 to 3.5. Bort diamonds, found in Brazil, Venezuela, and Guyana, are the most common type of industrial-grade diamond. They are also polycrystalline and often poorly crystallized; they are translucent and cleave easily. Because of its great hardness and strong molecular bonding, a cut diamond's facets and facet edges appear the flattest and sharpest. A
Carbonado, Washington Carbonado—the company also owned the houses and the energy resources as well. The energy resource in Carbonado was also the raw material that the citizens of the company town were harvesting, coal. During the time of the initial boom in the valley Carbonado grew to rival the size of Tacoma at the time. The railroad, which was integral to the transportation of people, of the raw materials harvested and the supplies need by the towns, stretched all the way up the valley too. Not only did it service the towns but also several homesteads farther up the valley. These homesteads
