Brucite is not often seen as particularly attractive specimens-- perhaps the most famous are the antique pieces from Pennsylvania, but those generally lack the color saturation of this one (and are generally priced in the thousands of dollars.)  Aside from the Pennsylvania pieces, there are also examples from the Kalahari Manganese fields and from the Urals ( both are blue to whitish gray) though they seldom have the same richness or visual appeal, and none but the finest few have a color saturations as good as the new Pakistani examples.
