Chrysocolla - drusy
stock #21.1-010
Inca De Oro, Chanaral
Atacama Region, Chile
6.3 x 3.6 x 1.6 CM (cabinet)
price: $250
new year 2021

Bright blue and with a sparkling druse of Quartz over the display face. Sawn on back it seems this was being fashioned into a jewelry item but was left unfinished. Displays well and the color is an excellent blue, with some green hues seen under strong lighting. The Chrysocolla finds from Chile was a major source of fine specimens for many years. These are no longer available and they have begun to increase in price quickly for choice pieces.

Lemanskiite with Lammerite and Olivenite
stock #20.1-901-(ZS-LEM4260)
El Guanaco Mine, Guanaco Santa Catalina, Antofagasta Province
Antofagasta Region, Chile
5.5 x 4 x 3.8 CM (cabinet)
price: $320
new year 2021

A rich showing of crystal clusters of the rare copper specie Lemanskiite from the type locality. Lemanskiite is a fairly new mineral recognized as unique in 1998. This piece also has a sizable ball of crystallized Lammerite (about 9 mm across) and a few sprays of Olivenite as well. The Lemanskiite is in micro crystals up to 2 plus mm radiating clusters that can be seen as distinct crystals by naked eye, but under magnification these are super impressive. This is a choice specimen of both Lammerite and Lamanskiite.

Krohnkite
stock #20.1-818
Chuquicamata Mine, Calama, El Loa Province
Antofagasta Region, Chile
5.6 x 4 x 2.7 CM (small cabinet/ large miniature)
price: $190
new year 2021

Bright blue to blue green masses of glassy Krohnkite from the type locality at Chuquicamata. A very colorful and rare mineral, this Copper Sulfate was only found in display grade specimens long ago. From every other locality worldwide I am unaware of any specimens over a few millimeters in size. This specimen is rich and colorful on all sides, there are no distinct crystals just masses and seams of Krohnkite.

Chrysocolla (drusy) with Malachite
stock #20.1-629
Inca De Oro, Chanaral
Atacama Region, Chile
7.1 x 3.7 x 3 CM (cabinet)
price: $700
new year 2021

Sparkling blue-green masses of Chrysocolla that has replaced earlier primary Malachite crystals. The entire surface is covered with tiny Quartz crystals that gives the drusy sparkle effect. Some very small bits of Malachite are still present but mostly this is all Chrysocolla. Some of the forms are fingers or stalactites in clusters, one of which has the look of a tree from the right angle. In excellent condition the color and form on this piece is outstanding. This locality has not produced any Chrysocolla for several years now. These replacements are a modern classic and in person this one is highly esthetic, far better than typical.

Brochantite - exceptional large crystals
stock #AC-373
Chuquicamata Mine, Calama, El Loa Province
Antofagasta Region, Chile
5.6 x 2.5 x 1.6 CM (cabinet)
price: $4500
new year 2021

An extraordinary and important old specimen of Brochantite from Chuquicamata, Ex Schortmann's and Immer Cook collection. The original label dates this to 1948-52, and by far it the best specimen I know of from this famed mine. This is certainly a serious contender for the best of specie outside of the 2016 Milpillas find. Even compared to the Mexican specimens this is a very significant stout cluster. The largest crystal is huge, 4.6 CM tall and quite thick. Close exam of the specimen finds a few slender needle crystals which are more typical of the specie. Under good magnification (40x) a few specks of blue that can be Krohnkite, Bellingerite or Aubertite etc are visible. There are areas of contacting making some rough edges but very little damage. A world class Copper secondary specimen.

Chrysocolla - druzy sprays
stock #20.1-325
Inca De Oro, Chanaral
Atacama Region, Chile
8.3 x 7.9 x 6.8 CM (cabinet)
price: $350
new year 2021

Colorful, sparkling sprays of radiating Chrysocolla filling a vug in ore. The drusy Quartz covers the Crysocolla and there is a zone of light blue druzy as well. In fine condition, this deposit has been exhausted for many years these Chrysocolla are modern classics.

Antlerite
stock #19.1-514
Chuquicamata Mine, Calama, El Loa Province
Antofagasta Region, Chile
6.3 x 4.4 x 4 CM (cabinet)
price: $580
Spring 2020

A superb very well crystalized example of this rare Copper Sulphate from Chuquicamata. Good Antlerite in prismatic crystals from this long ago find is not often available. These crystals are in the 3-4mm range which is about as large as any known from this legendary locality. Under magnification a variety of forms are noted and most of the individual crystals are well isolated, gemmy and brightly colored. This locale was at one time the source of many incredible rare copper minerals including rare copper Halides and what were for a century the worlds best Antlerites. A small newer find at Milpillas has since produced larger crystals with a different habit (and a far higher price). Chuqui was developed into one of the worlds largest open pits with efficient mechanized processes that now of course destroy any specimens at great speed. I have visited the site several times in the past decade but never found even a crumb worth obtaining, nothing is coming out. This piece is obviously from long ago.

Langite pseudo after Molybdenite
stock #18.1-622
Jardinera #1 Mine, Inca de Oro, Chanaral Province
Atacama Region, Chile
5.3 x 3.7 x 2.7 CM (small cabinet/ large miniature)
price: $390


An incredible, rare and exotic pseudomorph, Langite replacing bladed crystals of Molybdenite. This was collected by Terry Szenics at the Jardinera #1 Mine (where he discovered his namesake mineral Szenicsite). This was X-ray confirmed in 2009, and retains the Szenics label. There are areas of a dull grey material which seems to be altered Molybdenite that has not yet been replaced by the Langite. This is a remarkable, odd and rare specimen, the best example I have seen, very few were found and all were collected several years ago. The green blades reach 1.6 CM across and are distinct. A fine addition for any collection of pseudomorphs.
