Superb thoumbnail of lustrous intergrown Bisbee Azurite crystals. A complete undamaged floater, well crystallized all around. Historic, fine specimen. Ex. Jon Sigerman collection.

Cluster of double terminated Azurite crystals in a somewhat star-shaped formation. Areas of the Azurite have bright 'electric blue' coloration and areas that have have pseudomorphed to Malachite. Pristine condition. Ex. Jon Sigerman.

Elongated single Azurite crystal. Complete all around and transparent. Ex. Jon Sigerman collection. Jon acquired this from the Arkenstone which provided history and described it as 'a stunning, sharp, complete, GEM crystal of azurite, the absolute pinnacle of quality from Tsumeb. It was obtained from Charlie Key in the 1960s or 1970s...from the award-winning thumbnail collection of Sharon and William Panczner, author of the book Minerals of Mexico, and last seen and exhibited in the 1960s.'

Stunning doubly-terminated Azurite crystal set dramatically atop velvety Malachite and blue Shattuckite. The Azurite is complete all around, undamaged and translucent with sharp edges. Ex. Jon Sigerman collection.

Colorful specimen of Azurite and Malachite from the Sepon Mine in Laos. The Sepon Mine is a Gold and Copper mine located in south-central Laos and produced spectacular Azurite specimens that are reminiscent of Azurite from the Milpillas Mine in Mexico. This is a fine example with a somewhat triangular-shaped crystal that points straight up. The two side faces are bright blue with the front central face a blueish green due to alteration to Malachite. Complete all around and pristine. Ex. Irv Brown, Jon Sigerman.

Cluster of bright blue Linarite crystals from the famous Grand Reef Mine, one of the world's best localities for fine Linarite specimens. The Linarite is translucent with classsic 'electric' blue coloration. The crystals are not terminated but also not damaged, rather contacted at the ends from growth against the matrix. Ex. Jon Sigerman.
