|Malachite and Chrysocolla Polished Display
Stunning polished specimen from Kolwezi in the Katanga province of the Congo. This specimen measures 3.1 x 2.9 x 1.3"
(8 x 7.5 x 3.3cm) and weighs 7.1 oz or 0.44 lbs (202g). It is a combination piece consisting of layered deposits of
turquoise-blue Chrysocolla and rich green malachite. The polishing exposes the concentric deposits of different shades of
malachite and Chrysocolla forming bulls eyes. This piece has nice color variations, depths and formations...an exceptional
display specimen! We procured this piece from the Smithsonian Rock and Mineral Museum on our June 2013 trip.
|Chrysocolla (hydrated copper silicate) is a mineral, or more correctly classified as a mineraloid. It is of secondary origin
and forms in the oxidation zones of copper ore bodies. Associated minerals are quartz, limonite, azurite, malachite,
cuprites, and other secondary copper minerals.
Chrysocolla has an attractive blue-green color and is a minor ore of copper. It is typically found as glassy botryoidal or
rounded masses and crusts, or vein fillings. Because of its light color, it is sometimes confused with turquoise. The name
comes from the Greek chrysos, "gold", and kolla, "glue", in allusion to the name of the material used to solder gold, and
was first used by Theophrastus in 315 BC.
Malachite (Copper Carbonate Hydroxide) is a famous and very popular semi-precious stone. It is named for the Greek
word for "mallow", a green herb. Its banded light and dark green designs are like no other, and give it a unique
appearance unlike that of any other stone. The light and dark green bands are so distinctive that malachite maybe one of
the most easily recognized minerals in the world.
Many beautiful specimens of malachite contain special combinations with other minerals. Such combinations are some of
the most colorful mineral assortments in the mineral world. They include such stunningly colorful minerals as dark blue
azurite, sparkling black mottramite, blue chrysocolla, or rusty red limonite. So common is malachite that it is associated
with almost every secondary copper mineral whether they are carbonate minerals or not.
