15.0 x 14.2 x 10.7 cm. An aesthetic 7.5-cw-wide vug in rock and malachite is here hosting botryoidal, lustrous, sky blue chrysocolla spheres, to just over 3 cm in length. A few spheres have a coating of rich green malachite for added contrast. Overall a beautiful specimen representing a complete pocket as it was found. Most are broken open and trimmed to get smaller pieces which show the bubbly look of the chrysocolla. Intact nodules like this, showing how they form in nature, are harder to obtain. Mass over 2 kilograms.
5.6 x 5.3 x 4.7 cm. This is a very rare specimen. These were found in the early 1980s, and the specimen consists of small calcite crystals on dioptase that were completely replaced by the copper mineral plancheite and turned a rich blue in color. This is only at one end of the piece. At the other end, the calcites have been replaced by chrysocolla, I think; or at least so heavily coated one cannot tell and it’s a moot point visually. Ex. Ed Swoboda Pseudomorph Collection (see MinRec Nov/Dec 1997). He sold it to Carter Rich in 1999, who sold this to George Loud right after.
10.9 x 10.4 x 6.5 cm. Yes, this is a natural specimen of chrysocolla. This was a find not too long back at the copper-rich Star of the Congo Mine, of chrysocolla that is so strange and pretty you can hardly believe it is real. The botryoidal surface looks like molten plastic, and is an intense, deep robin’s-egg blue. This striking, sculptural cabinet specimen is covered with beautiful chrysocolla.
10.9 x 6.0 x 5.6 cm. Cornetite is a rare hydrated copper phosphate. This very fine, vuggy specimen in chrysocolla matrix is very richly lined with scintillating, vivid teal blue cornetite microcrystals. A striking and beautiful combination specimen. This fine piece is from a new find at the type locality - the Star of Congo Mine.
7.8 x 5.9 x 2.0 cm. Vivid, turquoise-blue chrysocolla covers the matrix plate on this fine specimen from the less well-known Douglas Hill Mine of Nevada. The chrysocolla has a weird and unusual pockmarked-look to it and some of the chrysocolla is very highly lustrous and botryoidal. Strange. The mine produces copper. Highly representative of the species and locale and seldom available. Ex. Wes Parker Collection, purchased from Doug Wallace who had a lot of this material in the 1990s.
5.4 x 2.3 x 1.6 cm. When these pseudomorphs were first discovered at the Ray Mine in 1976, they were X-rayed, which determined that the blue-green outer rim was chrysocolla after either gypsum or azurite. But a question was raised that the original crystallization appeared to be that of an unknown orthorhombic mineral, which would exclude both azurite and gypsum, both of which are monoclinic. The color has deepened over time with a natural patina, in this specimen, for when it first came out it was a sky blue. Most people seem to be labeling these as after azurite now, in this habit, although some others do look more like selenite and get that appellation. Ex. David and Emily Stoudt Collection.
A GORGEOUS and SPECTACULAR vug in chrysocolla of quartz-coated chrysocolla stalactites from the Ray Mine of Arizona. This piece has superb 3-dimensionality. 3.7 x 3.2 x 3.0 cm
4.8 x 3.4 x 2.4 cm. This very fine and sculptural specimen appears to be a complete-all-around floater in near pristine condition. The bubbly, botryoidal chrysocolla on the front is richly and attractively covered with scintillating, emerald-green malachite microcrystals. The amazing backside of chrysocolla looks like two attached crenellated, powder-blue, flower petals or human hearts. A fascinating and beautiful, two-sided, combination specimen.
So lustrous it looks WET - a rich and very pretty specimen of heterogenite (cobalt hydroxide - it is the dark botryoidal mineral on this specimen) with accents of chrysocolla. VERY HIGH QUALITY for this material! 9.3 x 7.4 x 3.5 cm
6.4 x 4.7 x 3.9 cm. A very colorful and striking combination specimen from a new find at the Star of the Congo Mine. Banded, green malachite is the initial coating on the very vuggy, sculptural matrix. Beautiful, bright powder-blue, botryoidal chrysocolla follows. Two generations of malachite are next: first is forest-green, botryoidal variety; followed by the scintillating, emerald-green malachite microcrystals. An exceptionally fine piece from this new find.
9.5 x 7.2 x 4.8 cm. Cornetite is a rare, hydrated copper phosphate. This very fine, vuggy specimen in chrysocolla matrix is very richly lined with scintillating, vivid teal-blue cornetite microcrystals. A striking and beautiful combination specimen, as the variable colors of chrysocolla are a fine compliment to the teal-blue cornetite. This extra fine piece, from a new find is from the Type Locality - the Star of the Congo Mine.
A showy cluster of blue quartz coating chrysocolla stalactites from the famous Ray Mine of Arizona. One side of the cluster is contacted, but does not diminish the beauty of this piece. 6.5 x 3.4 x 1.9 cm
9.7 x 6.4 x 6.0 cm. Cornetite is a rare, hydrated copper phosphate. This very fine, vuggy specimen in chrysocolla matrix is filled on five sides with very blocky and botryoidal scintillating, vivid teal-blue cornetite microcrystals. A striking and beautiful combination specimen, as the variable colors of chrysocolla are a fine compliment to the teal-blue cornetite. This fine piece, from a new find is from the type locality - the famous Star of the Congo Mine.
9.9 x 9.4 x 6.8 cm. An old-time, fine and rich combination specimen of pretty turquoise-blue chrysocolla botryoids nicely accented with sparkly, emerald-green, primary malachite microcrytals in bubbly form. Chrysocolla is relatively rare from the Bisbee District. Old-time, highly representative and uncommon combination material from the W. Simpson and Dennis Mullane Collections.
12.1 x 6.7 x 2.8 cm. Yes, this is a natural specimen of chrysocolla. This was a find not too long back at the copper-rich Star of the Congo Mine, of chrysocolla that is so strange and pretty you can hardly believe it is real. The botryoidal surface looks like molten plastic, and is an intense, deep robin’s-egg blue. For color and uniqueness, this represents one of the most unusual new finds of the past couple of years. This striking, sculptural, cabinet specimen is solid chrysocolla.
