This tarbuttite specimen is covered with bright, sparkling crystals on a dark brown gossan matrix. The tarbuttite is sharply crystallized, colorless, and highly lustrous. This is a highly representative specimen from the type locality for this rare zinc phosphate. This locality has produced some of the finest specimens of the species ever found. The Broken Hill Mine (also called the Kabwe Mine) was a lead-zinc-silver mine that opened in 1906, and continued to produce until 1989.
