Electric Blue Chalcanthite
from Poland

$72.00
Large Laboratory grown
Electric Blue
Chalcanthite display
specimen.

This specimen is from our
personal collection and is a
beautiful example of quality
lab grown crystals from
Boleslawiec, Poland.

The color is an excellent shiny
electric blue with many nicely
formed crystals. The color is
actually a darker blue in
person. The crystals reflect a
lot of light.

This specimen weighs
0.93 lbs or 14.96 oz (423g)
and measures
4.8 x 3.9 x 3 inches
(12.3 x 9.9 x 7.8cm)

Due to the fragile nature of
these crystals this item ships
in its own box and cannot be
combined shipping with other
items. Shipping weight is
calculated at 2 lbs with
packing materials.

Chalcanthite is a water soluble copper sulfate. As chalcanthite is a copper mineral, it can be used as an ore
of copper. However, its ready solubility in water means that it tends to crystallize, dissolve, and recrystallize
as crusts over any mine surface in more humid regions. Therefore, chalcanthite is only found in the most arid
regions in sufficiently large quantities for use as an ore.

Secondarily, chalcanthite, due to its rich color and beautiful crystals, is a sought after collector's mineral.
However, as with its viability as an ore, the solubility of the mineral causes significant problems. First, the
mineral readily absorbs and releases its water content, which, over time, leads to a disintegration of the
crystal structure, destroying even the finest specimens. It is critical to store specimens properly to limit
exposure to humidity. Second, higher quality crystals can be easily grown synthetically, and, as such, there is
a concern that disreputable mineral dealers would present a sample as natural when it is not.

Chalcanthite's blue color is one of its most notable features, but it is insufficient in identification. Other useful
tests include associated minerals, crystal habit, solubility and subsequent coloring of the water blue, and
taste. A special note on tasting chalcanthite, however: chalcanthite has a sweetly metallic taste, but taste
testing should not be done haphazardly. The specimen should be never touched with the tongue, as
chalcanthite is poisonous. The liquid from chalcanthite will also stain skin blue for several days.

Most of the Chalcanthite sold to collectors is laboratory grown and presents an excellent electric blue display
specimen for your cabinet. Chalcanthite should always be kept inside a cabinet to prevent young children
from reaching out and touching the "pretty blue rock"
Item #1CHN10160001
Natural Blue Chalcanthite
from New Mexico

$22.00
Beautiful Natural Electric Blue Chalcanthite display specimen.

This specimen is from our personal collection and is a beautiful example of natural secondary copper crystals
from Socorro, New Mexico. The color is an excellent shiny electric blue with a nicely formed crystal formation.
This crystal has been sprayed with polyurethane to help seal out the moisture. These crystals will disintegrate
if kept in an environment with moisture unless they are sealed. This is a natural specimen collected by a
geology/mining student at New Mexico Institute of Mining and Technology (New Mexico Tech) from a copper
mine in the Magdalena Mountains near Socorro, NM. It has been in our collection for over 20 years now.

This specimen weighs 2.5g and measures 1.3 x 0.6 x 0.3 inches (35 x 17 x 9mm)
