From the collection of adamite connoisseur Marty Zinn, a specimen with relatively large isolated bipyramidal crystals of adamite (rather than the usual clusters of microcrystals) to over one centimeter! Fine luster, color and translucency too. Adamites such as this are quite rare in comparison to the more familiar whorls and pinwheels. 5.3 x 5 x 2.3
