13.3 x 10.0 x 3.3 cm. A really good specimen from this relatively recent find of warty-looking (in an attractive way!) black heterogenite, bubbled up richly upon a crust of bright blue chrysocolla. Ex. Charlie Key Collection.
10.6 x 6.4 x 5.6 cm. Yes, this is a real, natural, unretouched specimen of chrysocolla, from a recent find in Congo. These are unlike any specimens of any mineral I have seen - almost PLASTIC-like in appearance, with a wet-looking, melty surface. Truly a very unusual copper-mineral specimen, and pretty, too - with deep, saturated turquoise color. The matrix here is covered all around and on both sides with chrysocolla.
8.7 x 7.9 x 5.7 cm. This is a heavy specimen of SOLID chrysocolla and malachite, in a gorgeous balance, with beautiful banded bul’l-seyes. Malachite comes out of this area in high quantities, but when it is intermixed with chrysocolla, it is really sought-after for the obvious reason of its great beauty. It is REALLY hard to find ones like this where the two colors are in such a great balance and you get the beautiful malachite patterns in a "sea" of deep turquoise blue. These tend to get grabbed very quickly. This large piece is polished all over to bring out the beauty.
7.5 x 5.6 x 4.8 cm. This is a now very rare Arizona old-timer: a thick layer of translucent, botryiodal quartz on deep robins-egg blue chrysocolla, which in turn is on underlying malachite. The covering of silky quartz appears almost as if added to dress up the chrysocolla underneath, giving it the appearance of a translucent smithsonite. The color is glorious!
9.9 x 8.4 x 5.9 cm. This is a large, very rich specimen of chrysocolla from what is probably the most classic locality in America. You can see various shades of robin’s-egg blue and green (there is some malachite but the vast majority of this is chrysocolla). There is a shallow pocket with some botryoidal forms in it. I would say about 50% of this large, thick nodule is chrysocolla (the rest being matrix).
9.3 x 7.4 x 5.3 cm. A big, thick specimen of SOLID chrysocolla and malachite, which is actually tightly banded (from sedimentary deposition) if you look at it from the side. The specimen has been polished to bring out its beauty.
12.2 x 7.4 x 6.0 cm. We have had a couple of these Arizona classics in the auctions lately, from completely different collections. They have always been favorites - robins-egg blue chrysocolla covered with a coating of sugary, sparkly quartz. And, they have never been available in quantity, so they get good money on the market. This is a large and very impressive one! The label that came with it is from dealer Claude Humber, and indicates that he collected it himself at the mine in 1975.
5.6 x 1.4 x 0.7 cm. The quartz-on-chrysocollas from Arizona have always been prized by collectors, for their beautiful color and the sheen given them by the overlying quartz. When they form actual stalactites, such as in the case of this specimen, they are very highly sought-after. This is such an elegant mini -- with three spires rising dramatically side-by-side. They are perfect and undamaged - with gorgeous robins-egg blue color.
9.6 x 7.4 x 5.2 cm. Though it hardly looks real, this is natural, unpolished chrysocolla with a truly bizarre look to it, as if melted - from a recent find in Congo. It has intense deep turquoise color and again, this UNIQUE melty surface!
5.4 x 5.2 x 1.5 cm. These specimens certainly have been few and far between. I personally have only seen about five of them over the last few years. This specimen features several sparkling, gemmy, lustrous, water-green color spherical aggregates of Prehnite associated with dark blue-green color Chrysocolla aggregates which are sprinkled over the surface. It is not terribly common to find isolated Chrysocolla aggregates, and although these are somewhat weathered, the association with unusual and attractive to be sure. Ex. Brian Kosnar Collection.
12.4 x 7.9 x 4.3 cm. This beauty, out of the Hauck collection, is for the cabinet collector - and boy, is it showy and magnificent! The bright robins-egg blue chrysocolla is covered by a druse of sparkly quartz, filling a shallow recess that curves 3-dimensionally around the top of the specimen. This pocket measures 8 cm in length! Even small specimens of this classic Arizona combo are prized, and big ones such as this are just so hard to get.
4.7 x 4.2 x 3.1 cm. These have always been well-loved by collectors - quartz druse over deep robins-egg blue chrysocolla, here thickly filling a seam. The quartz has formed a pretty snowball in one place!
8.8 x 6.2 x 4.5 cm. A large, solid nugget of malachite with highlights of robins-egg-blue chrysocolla - polished to bring out the beauty.
8.0 x 4.8 x 2.6 cm. A gorgeous specimen with an antique Ward's Science Establishment label dating it to pre-WWI in the early 1900s. Ward's was an active buyer at the time, but an even older (unidentified, calligraphy) label glued to the back indicates this may date to the earliest days of copper camp mining in Arizona. However, the pedigree aside, it’s just an incredible specimen with eye appeal due to the startling contrast of the (8mm) primary malachite crystals to the blue quartz underneath. It was, in Hauck's collection, a stunning blue quartz representative...but it’s more than a mere quartz in my book!
6.3 x 5.1 x 3.4 cm. Pseudomalachite is a phosphate, NOT a carbonate like malachite, and the two are often mixed up in favor of malachite. This is an excellent, showy, display-sized specimen from this famous occurrence, one of the great classic finds for the species.
