Libethenite - unusual rosette habit from type locality
stock #15.1-715
Lubietova, Slovenske Rudohorie Mts,
Banska Bystrica Region, Slovakia
6 x 4.8 x 3.6 CM (cabinet)
price: $350
new year 2021

An excellent very old Libethenite from the type locality with well-formed rosette structures. This habit is quite rare from Lubietova (originally Libethen) and these are sizable up to 5 mm which is large for any locale. From the collection of Dr Warren Johannson, his label notes he obtained it in a trade with Amherst College in 1982. The rosettes are in very good condition having been protected in a vug.

Euchroite - well-crystallized, type locality
stock #17.1-715
Lubietova, Slovenske Rudohorie Mts,
Banska Bystrica Region, Slovakia
1.6 x 1.5 x .8 CM (thumbnail)
price: $300
new year 2021

Super crystals of the rare Copper Arsenate Euchorite from the type locality. The color and form are especially nice on this thumbnail, there is a slight translucence and classic waxy luster. Examination with good magnification finds a few tiny rough spots and the backside is incomplete, but by naked eye the condition is excellent. Though not perfect the quality for this rare specie is still very fine and not often available. A slightly bent or curved aspect to some faces is noted as was often the case in the larger crystals in the type locality. These crystals are very large for the locality and for the specie. An older specimen, Ex Rejl collection.

Pseudomalachite
stock #19.1-406
Lubietova, Slovenske Rudohorie Mts,
Banska Bystrica Region, Slovakia
9 x 7.7 x 4.6 CM (cabinet)
price: $480


Large and superb, rich old specimen of Pseudomalachite from the ancient mining area of Lubitova. This locality was called Libethen by the Germans and Libetbanya by the Hungarians, but is now in Slovakia, and is Lubitova. Mined since the Bronze age and closed in 1863, this is one of the great locales of Europe and this specimen is an outstanding Pseudomalachite which has formed on and arround a gossan type matrix. In addition to the large botryoidal green masses there are hundreds of tiny spheres and a few stalactitic fingers in a dense mass of deep green. Very fine piece for the specie and for the locality.

Posnjakite
stock #18.1-511
Spania Dolina, Banska Bystrica County
Banska Bystrica Region, Slovakia
6.2 x 3.9 x 3.1 CM (small cabinet/ large miniature)
price: $140
Dec 2018

A fairly dense deep blue color mass of crystalized Posnjakite from Spania Dolina. This ancient Copper mine has been worked for over 1000 years and probably even in the Neolithic era. At times known as Herrungrund (German periods often seen on old labels). This deposit is very large and has many old mines along a belt of several kilometers. This zone has produced a number of colorful Copper species along the oxidized zone of the deposit. Thgis is a choice specimen for the area.

Langite
stock #16.1-1282
Spania Dolina, Banska Bystrica County
Banska Bystrica Region, Slovakia
12.2 x 9.1 x 5.3 CM (cabinet)
price: $360
Worldwide mix summer

Incredibly rich, a large old Langite specimen with a fine blue-green color that is quite intense. This secondary copper Sulphate specie is a dimorph of Wroewolfeite and can be confused with it or Posnackite. While Langite is found as micros at many localities, the best and largest specimens are mostly from old Slovakian mines. The matrix here has at least some Langite on every side, but the 3 main faces have the best coverage and most distinct crystals. This could easily be made in to several very good specimens but we like the large size for impact. Formerly in the Vrzal collection in Brno, Czech Republic.
