ex. ex. Chicago Field Museum ex. Dr. Edward David ex. Maynard Bixby
This remarkable oldtimer came from the Maynard Bixby collection, turn of 1900s, to Chicago Field Musuem. (see the purchase note on the museum's accession card!). They essentially liquidated their musuem collection to Dave Crawford in the late 1980s, and he sold it to Ed, so we have the whole trail from 1905 til now, of ownership. it was probably found when Utah wasnt even a state. its the largest i have seen, best i have seen, and only good one i have seen for sale beyond a small specimen. Truth be told, I am thinking of trimming in half to keep one half as profit and i bet the other half would still probably go for the same 5000. These just are NOT around to be had, it is big, and it is pretty after all..

These just are NOT around to be had, it is big, and it is pretty after all.. 17 x 12 x 5 cm
9.7 x 6.3 x 6.0 cm. A pristine, lustrous, hematite-included calcite rhomb nicely attached to a conichalcite crust from Tsumeb. This large, 4.0 cm, nail-head crystal has good lustre and outstanding stepped-growth faces. Excellent material from the George Elling Collection.
10.4 x 8.9 x 4.2 cm. What you see here as a field of pretty, powdery green conichalcite here is actually made up of thousands of tiny crystalline balls. They form a solid field on the underlying limonite matrix. Pretty contrast between the moss green and rust colors. Quite a large plate for the locality!
6.5 x 4.8 x 1.5 cm. Sparkly, dark grass-green conichalcite microcrystals cover botryoidal hematite matrix on this CLASSIC specimen from the famed Mina Ojuela of Mexico. This is very fine, older material and typical from this well-known locality. Ex. John Ydren Collection.
7.0 x 3.9 x 2.2 cm. This specimen starts with a layer of crystallized clear to white calcite rhombohedra upon which sit emerald green, lustrous dioptase crystals up to 3mm; and on top of this are spherules of forest green conichalcite to 3mm. Ex. Willy Israel Collection.
7.9 x 4.8 x 3.1 cm. A carpet of mossy-green conichalcite from Mexico - actually with small, translucent scalenohedral crystals if you look closely in addition to brushy patches. Conichalcite (Calcium Copper Arsenate Hydroxide) forms in the oxidation zone of copper ore bodies; the best-known specimens are from Mexico. This is a superb example of this find and style. Ex. Consie Prince Collection.
7.2 x 4.3 x 2.7 cm. A striking combination specimen from the Mohawk Mine of San Bernardino County, California. Powder-blue tufts and needles of rosasite are beautifully complimented by apple-green conichalcite and fill compartments on both sides of the amazing, shoe-shaped gossan matrix with excellent, box-work structure. Outstanding, rare, old-time and seldom available material from this locale. Ex. Jaime Bird Collection.
9.0 x 7.4 x 2.4 cm. Two fields of sparkly, rich, forest-green, botryoidal conichalcite are aesthetically separated by a ridge on goethite on this fine and sculptural specimen from the Mina Ojuela of Mexico. Ex. Consie Prince Collection.
6.7 x 5.0 x 4.8 cm. Sparkly, grass-green conichalcite microcrystals beautifully accented with glassy, colorless calcite crystals cover both sides of the crest of the very lightweight, bubbly, botryoidal limonite matrix on this very striking and colorful specimen from the Mina Ojuela. This fine piece probably dates to the 1970s finds at this historic locale. Ex. Consie Prince Collection.
A gorgeous Mexican combo specimen, featuring sharp clusters of calcite perched on a combo of tiny ball-shaped conichalcite on a plate of bright green cuproadamite microcrystals. (NOTE CORRECTED TEXT) 9.6 x 7.1 x 3.0 cm
5.8 x 4.1 x 1.3 cm. Higginsite is a synonym for conichalcite and is named after the less well-known Higgins Mine at Bisbee. Lustrous, apple-green conichalcite microcrystals richly cover the matrix plate on this old-time specimen. Conichalcite is a relatively uncommon copper arsenate found in the oxidized zones of copper deposits. Ex. Dennis Mullane Bisbee Collection and comes with a Warner & Grieger label. They were prominent California dealers and collectors prior to World War II. Primary production from the Higgins Mine was from 1913-1929. Old-time material.
8.5 x 4.7 x 3.2 cm. A very bright, stunningly white calcite layer covers a carpet of intense green conichalcite here…a classic from this old mine in Utah. The calcites form as dogtooth scalenohedrons, and completely cover the top surface. Ex. Harold Urish Collection.
4.6 x 4.4 x 1.4 cm. Self-collected in 1979 when this locale was still accessible to collectors, this is a rich specimen of intense green conichalcite, with minor pastel green austinite in association. Rare material, today. Ex. Harold Urish Collection.
An excellent and rich, old-time specimen of forest-green, micro-crystals of conichalcite richly covering gossan matrix. The CLOTH label on the specimen tells you, that this is an OLD piece from the Park City District, Utah. In fact, conichalcite is VERY UNCOMMON from Park City. Ex Richard Hauck Collection. 7.9 x 6.3 x 3.8 cm
