CHC16 Calcite
Daye Mine, Daye Co., Huangshi Prefecture, Hubei Province, China
9.0x 6.6x 6.4 cm
$92
A nice example of a "pagoda calcite" from the Daye Mine, these were found many years ago, though there was a find late last year as well. This piece comes from the newer find, minor scuffing though in pretty good condition overall.
CHC17 Quartz with Sphalerite.
Palomo Mine, Castrovirreyna Prov., Huancavelica Dept., Peru
10.0x 7.8x 5.0 cm
$68
A quartz plate with interspersed sphalerite crystals, and some pyrite. The Palomo Mine produced a lot of material in the early 2010's, then production suddenly stopped. This is the locality best known for producing the Peruvian realgar.
CHC18 Datolite
Centennial Mine, Houghton Co., Michigan, United States
6.8x 5.6x 1.8 cm
A decently sized, polished datolite nodule half from Michigan's Upper Peninsula. This one has a couple splotches of green that identify it as being from the Centennial Mine

Erongo Mountain, Erongo Region, Namibia
4.5x 1.9x 1.8 cm
A nice example of purple fluorite crystals clinging to the side of a schorl crystal, from Erongo Mountain, Namibia
CHC20 Calcite in Clam Fossil
Rucks Pit, Fort Drum, Okeechobee Co., Florida, United States
9.6x 5.6x 4.3 cm
$68
A nice reference example of orange-yellow calcite crystals in a fossilized clam, from Florida.
CHC21 Pyrite
Jiangxi Prov., China
7.1x 5.5x 3.5 cm
A ball-shaped aggregate of pyrite, on a calcite covered matrix.
CHC22 Veszelyite
Kunming District, Yunnan Prov., China
5.6x 3.8x 2.8 cm
$96
A nice example of the very rare species veszelyite, from a recent find in southwestern China. These are best known from the 60's-70's finds at the Black Pine Mine in Idaho, USA-- for decades those were the only available examples. Then around 2020-2021, there were two nearly simultaneous, separate finds of the species in both the Republic of Congo and China.
CHC23 Fluorite
Erongo Mountain, Erongo Region, Namibia
3.9x 3.5x 2.5 cm
$58
A vivid green (with the correct light) etched fluorite crystal on a muscovite-rich matrix, with (I think) a small magnetite or hematite crystal next to it.
CHC24 Feldspar/ Amazonite
Klein Spitzkoppe, Erongo Region, Namibia
6.5x 4.8x 4.3 cm
$68
A satisfyingly chunky feldspar crystal from Klein Spitzkoppe, with a couple areas of bluish amazonite. Some contacting on the reverse, but displays well from multiple angles-- it looks kind of like a plaster crystallographic model. This location is best known for its topaz, but also produces beryl, smoky quartz, and feldspar.
CHC25 Fluorite on Schorl Tourmaline
Erongo Mountain, Erongo Region, Namibia
4.6x 3.3x 3.0 cm
$96
A really interesting example of fluorite on schorl, a sort of lollipop.... pieces like this are why I love Erongo-- the species associations themselves may not be terribly unusual, but the ways they are combined tend to be particularly unique!
CHC26 Copper
Katanga Copper Crescent, Katanga, Democratic Republic of Congo
9.3x 3.6x 2.9 cm
A very rare example of copper from the Katanga Copper Crescent region of the Southern D.R. Congo. It might sound ridiculous for copper to be rare in a region bearing its name, and that also happens to contain one of the world's richest deposits of the metal, but native copper is almost never seen as specimens from here. These are rather crude crystals, but you can definitely see the form of the copper, and they seem have a surface alteration of cuprite.
CHC27 Pyrite, Chalcopyrite, and Quartz
Jiangxi Prov., China
10.3x 6.8x 2.5 cm
A beautiful plate of quartz crystals with chalcopyrite accents, some of these in turn have overgrowths of pyrite, adding an extra sparkle.
CHC28 Fluorite
Auglaize Quarry, Junction, Paulding Co., Ohio, United States
5.8x 5.0x 3.7 cm
A sample of highly sought after (at least here in the Midwest) purple fluorite from the Auglaize Quarry, in Ohio. The side crystal is cleaved-- still, a very good reference for the price.
CHC29 Copper
Keweenaw Peninsula, Michigan, United States
6.7x 3.7x 1.4 cm
A sample of crystalized copper from Michigan's Upper Peninsula. There are some good crystal faces near the top of the specimen.
CHC30 Pyrite
American Aggregates Quarry, Indianapolis, Indiana, United States
3.8x 3.7x 2.7 cm
$42
A nice ball-shaped aggregate of pyrite crystals from a quarry near Indianapolis.
CHC31 Quartz var. Amethyst (Enhydro)
Goboboseb Mtns., Brandberg Area, Erongo Region, Namibia
5.4x 2.6x 2.3 cm
A beautiful quartz specimen with amethystine zoning, from the Goboboseb Mountains. This crystal has a small moving bubble.
CHC32 Quartz var. Amethyst
Erongo Mountain, Erongo Region, Namibia
5.4x 2.8x 1.9 cm
$48
A reference example of amethyst from Erongo mountain, and a scepter too. Amethyst is quite common from the Goboboseb area, located many km northwest of Erongo, but it's quite uncommon on Erongo itself. This comes from a recent discovery.
CHC33 Slag
Tsumeb Mine, Otjikoto Region, Namibia
7.0x 5.5x 2.0 cm
$56
Not a mineral, more of a mining/historical oddity for all the Tsumeb buffs out there-- this is a piece of slag, the waste product of ore refined at Tsumeb decades ago. For obvious reasons, the miners didn't bother selling these, though I've seen a couple in collections and I suppose it would be something of a curio for those with a special interest in this historic locality.
CHC34 Smoky Quartz
Goboboseb Mtns., Brandberg Area, Erongo Region, Namibia
7.2x 3.2x 2.5 cm
A very beautiful example of enhydro quartz from the Goboboseb area, with light smoky zoning and a trapped water bubble.
CHC35 Prehnite
Goboboseb Mtns., Brandberg Area, Erongo Region, Namibia
6.4x 5.3x 4.2 cm
$58
A nice reference sample of green prehnite on matrix, from the area best known for its world class amethyst specimens.
CHC36 Fluorite
Erongo Mountain, Erongo Region, Namibia
4.5x 2.7x 3.0 cm
$48
An interestingly shaped luster of green fluorite crystals fro recent finds on the southern face of Erongo Mountain.
CHC37 Calcite
Pugh Quarry, Weston, Wood Co., Ohio, United States
6.6x 5.8x 2.4 cm
$48
A nice example of orange fluorite from the Pugh Quarry, in Ohio.
CHC38 Fluorite
Madoc, Ontario, Canada
6.0x 4.8x 3.3 cm
$46
A reference sample of light green fluorite from one of the less frequently encountered localities for the species.
CHC39 Fluorite on Schorl Tourmaline
Erongo Mountain, Erongo Region, Namibia
5.1x 3.9x 3.0 cm
$64
A nice example of fluorite on a cluster of fibrous tourmaline. As is often the case with Erongo, the fluorites show interesting zoning, with areas of green, colorless, and purple.
CHC40 Bournonite
Machacamarca District (Colavi District), Saavedra Province, Potosi Department, Boliviah
6.3x 3.3x 2.5 cm
A nice sample of bright bournonite crystals on matrix, from finds made in 2021.
CHC41 Schorl Tourmaline on Quartz
Erongo Mountain, Erongo Region, Namibia
5.8x 4.4x 4.4 cm
$58
A nice example of an elongated schorl crystal on quartz, from recent finds on Erongo Mountain.
CHC42 Lazurite
Sar-e-Sang, Badakhshan, Afghanistan
8.0x 5.0x 5.1 cm
A nice example of lazurite from the Sar-e-Sang mines of northeastern Afghanistan-- lazurite has been collected at this location for over 5000 years. This one features one sharp, well exposed crystal, along with a slightly rougher one and a third larger crystal section exposed in the marble matrix.
CHC43 Smoky Quartz with Schorl Tourmaline and Hyalite Opal
Erongo Mountain, Erongo Region, Namibia
8.2x 7.2x 3.8 cm
$76
A nice example of smoky quartz with lustrous schorl tourmalines near the base. The main quartz crystal has a sort of "boa" wrapped around near the top. There is chipping not he main quartz, though still particularly good from overall.
CHC44 Corundum var. Sapphire
Transvaal, South Africa
5.7x 3.9x 2.9 cm
$58
A decently sized sapphire crystal from South Africa, showing rather good form.
CHC45 Muscovite with Fluorite
Erongo Mountain, Erongo Region, Namibia
6.5x 4.5x 3.5 cm
$74
An unusual example of muscovite with fluorite from very recent finds on the southern face of Erongo Mountain.
CHC46 Beryl var. Aquamarine on Schorl Tourmaline
Erongo Mountain, Erongo Region, Namibia
4.3x 1.8x 1.5 cm
An unusual example of small blue aquamarines on schorl. Erongo produces such odd combinations-- seeing these two species together is nothing new, in fact it is downright common from Pakistan-- but the odd ways that various species grow together at Erongo is what makes it one of my favorite localities.
CHC47 Calcite
Pugh Quarry, Weston, Wood Co., Ohio, United States
10.0x 5.4x 5.1 cm
A nice example of orange calcite from the Pugh Quarry, in Ohio.
CHC48 Alabandite
Uchucchacua Mine, Oyon Prov., Lima Dept., Peru
7.5x 5.2x 5.0 cm
$112
A nice crystallized example of this rare manganese mineral from the Uchucchacua Mine, better known for its rhodochrosite, silver, and silver sulfosalts. This piece comes from a find made around 10 years ago.
CHC49 Beryl var. Aquamarine on Smoky Quartz
Erongo Mountain, Erongo Region, Namibia
3.8x 2.2x 2.3 cm
$56
A nice example of gemmy aquamarine on a smoky quartz crystal, from recent finds on Erongo Mountain.
CHC50 Smoky Quartz with Schorl Tourmaline
Erongo Mountain, Erongo Region, Namibia
7.8x 3.5x 3.5 cm
$69
A very nice smoky quartz crystal from recent finds on Erongo-- it also has included schorl needles.
CHC51 Barite
Rock River, Yukon, Canada
6.8x 4.8x 4.3 cm
$64
A reference sample of barite from a very remote location in northwestern Canada-- not perfect, but not a common locality.
CHC52 Calcite
Erongo Mountain, Erongo Region, Namibia
3.8x 2.7x 1.3 cm
$42
A very odd calcite rhomb from Erongo-- it has the standard crystal shape, but very unusual zoning-- some kind of sand inclusions perhaps? I'm used to seeing this sort of thing with selenite, though it's the first time I can recall seeing such clear zoning (presumably caused by sand) in a calcite crystal.
CHC53 Fluorite
Goboboseb Mtns., Brandberg Area, Erongo Region, Namibia
5.1x 3.8x 2.9 cm
An odd new discovery from Namibia's Brandberg Regoin: clusters of orangish-brown fluorite. If you walked up to me in Tucson and showed me this, my first guess would probably be Henan Province, China.... but it's actually from the area best known for its world-class Amethyst.
CHC54 Calcite
Sweetwater Mine, Reynolds Co., Viburnum Trend Dist., Missouri, United Statese
7.1x 5.2x 4.3 cm
$64
A decently sized, orangish yellow calcite crystal from the Sweetwater Mine, in eastern Missouri.
CHC55 Manganocalcite
Racracancha Mine, Tinyahuarco Dist., Pasco Prov., Pasco Dept., Peru
4.5x 3.6x 3.6 cm
A nice reference sample of a manganocalcite twin on a black sphalerite matrix, from old finds at the Racracancha Mine, in Peru. These have a patchy, bright pink fluorescence.
CHC56 Fluorite on Schorl Tourmaline
Erongo Mountain, Erongo Region, Namibia
3.6x 2.6x 2.6 cm
$58
A pair of fluorite crystals on a spray of schorl tourmaline crystals, from Erongo. As with many Erongo fluorites, the internal zoning of the crystals makes the color somewhat odd and highly dependent on lighting-- its somewhere between purple and dark green, depending on the light.
CHC57 Dolomite
Barett Quarry, Norwood, St. Lawrence Co., New York, United States
4.1x 3.7x 3.6 cm
$36
An old example of well crystalized, pinkish Dolomite from Upstate New York. Old material dating to the 1970's.
CHC58 Brazilianite
Linopolis, Minas Gerais, Brazil
3.8x 2.4x 1.6 cm
$48
A terminated crystal of greenish-yellow brazilianite from Linopilis.
CHC59 Schorl Tourmaline, Tessin Quartz
Erongo Mountain, Erongo Region, Namibia
6.2x 5.6x 3.4 cm
$68
A nice example of smoky tessin quartz on a schorl matrix, from recent finds on Erongo.
CHC60 Calcite
Berry Materials Corp. Quarry (North Vernon Plant), North Vernon, Jennings Co., Indiana
4.8x 4.0x 3.6 cm
$58
A nice example of calcite from the Berry Materials Quarry, displaying the very distinct rounded appearance and color typical of specimens from this location.
CHC61 Calcite
Lehigh Cement Quarry, Mitchell, Indiana, United States
7.1x 4.6x 2.1 cm
A doubly terminate calcite crystal from a cement quarry in Indiana-- the American midwest is dotted with various quarries that produce everything from food grade silica to frac sand, a number of these also produce their own distinct habits of calcite, celestite, or fluorite.
CHC62 Quartz Scepter
Erongo Mountain, Erongo Region, Namibia
6.0x 3.3x 2.2 cm
An unusual little quartz scepter attached to the side of another crystal section, from recent finds on Erongo Mountain.
CHC63 Prehnite
Goboboseb Mtns., Brandberg Area, Erongo Region, Namibia
4.6x 2.4x 3.3 cm
A nice green cluster of prehnite crystals on matrix, from the Brandberg area of Namibia.
CHC64 Schorl Tourmaline
Erongo Mountain, Erongo Region, Namibia
6.1x 5.2x 3.3 cm
$38
A nice example of very sharp, lustrous schorl crystals scattered about on a feldspar matrix. From recent finds on the south eastern side of the mountain.
CHC65 Calcite
Erongo Mountain, Erongo Region, Namibia
4.1x 1.2x 1.0 cm
$40
An unusual calcite crystal from Erongo-- for all the species that this area produces, calcite is definitely not one that comes to mind. This piece has an unusual, elongated habit.
CHC66 Fluorite on Orthoclase
Erongo Mountain, Erongo Region, Namibia
6.8x 2.4x 2.3
A single, dark purple fluorite crystal clinging to the side of a twinned orthoclase.
CHC67 Barite
Gravois Mills, Morgan Co., Missouri, United States
