PIERRE MARCASSITE – HIS HISTORY

Marcassite stone, also called “fool’s gold” for its gold-like luster, was named after the ancient Arabic word “marqachita”, which meant all pyrite minerals at the time. Although it could be mistaken for gold in the past, it was first distinguished from pyrite in 1814 by French mineralogist René Just Haüy, then accurately described in 1845 by Austrian mineralogist Wilhelm Karl Ritter von Haidinger. These two scientists greatly contributed to the development of knowledge and the enrichment of gem collections in Europe. Modern techniques for testing stones no longer allow for confusion.

Marcassite stone has been used since prehistoric times to produce fire by percussion with a hard rock such as granite, flint or quartz. Upper Paleolithic, Mesolithic and Neolithic man used this stone because of its combustion by exothermic oxidation, caused by iron and sulfur particles torn off on impact. The resulting sparks were then directed at tinder or other fine plant material to start a fire. Today, percussion ignition kits containing a lighter, flint and marcasite are commercially available.

Interest in marcasite stone has been fickle through the centuries. In Europe, it has mainly been used for ornamentation, following social trends and codes. Initially, it was used to embellish brooches, medallions and shoe buckles, before losing popularity for a long period. Its revival came in the 19th century, when large quantities of marcasite were imported to Paris. The French used this stone in the same way as antique jewelry, which was very popular in Paris and Geneva. During the Second EmPire, French women were particularly fond of this jewelry, whose price was equivalent to that of gems and precious metals. In Victorian England, it was cut in a regular, symmetrical pattern (round or square) and then set to create a sparkling pavage, like rivers of diamonds. Women readily associated this sparkling stone with their refined or lacy outfits. The rococo style in vogue during the reign of Louis XV was the insPiration for its combination with colored glass pastes and enamels. Its popularity waned, however, when its production became less qualitative and too commonplace. Nevertheless, a few decades later, it became popular again, succeeding the black diamond of the Roaring Twenties. With the economic crisis in full swing, it became a fashionable stone, mounted on jewelry insPired by the Art Deco style characteristic of the 20s.

Currently, the vintage trend is bringing marcasite stone back into fashion by pairing it with silver to give historical authenticity to clothing, reminiscent of the Victorian era. Peru was once the main source of the large slabs of this rock used to make mirrors, but they are now nowhere to be found. European mines, in particular the Jura and German deposits, provide small specimens of around two carats. It’s the jeweler’s meticulous work that reveals the luminous brilliance characteristic of pyrite gems. The “rose” cut combines a flat base with triangular facets, taking advantage of the mineral’s opacity to reflect light. Mounted in pavé on white metals or silver, they offer a particularly brilliant sparkle.

MARCASSITE STONE – ITS ORIGIN AND COMPOSITION

Pyrite and marcasite are very similar in that they have the same composition, hardness and appearance, and come from the same deposits. Only their structure differs, with pyrite being more stable than marcasite. Their names have different etymological origins, one referring to a Persian province, the other to the ancient Greek word for “fire”. Marcasite is pale yellow-bronze, coppery-gray and opaque, and creates characteristic inclusions in other minerals, such as laPis lazuli, making each specimen unique. Composed of ferric sulfide, it is found in sedimentary rocks such as chalk and carbonaceous rocks such as coal. It is formed during diagenesis, a chemical process that transforms sediments into rocks, in an environment deprived of air and in the presence of hydrogen sulfide. For this process to occur, the temperature must be low or moderate. The iron oxides present in the rock are first transformed into ferric sulfide, then into ferric disulfide.

The pH of the medium in which diagenesis takes place is decisive: an alkaline pH favors the formation of pyrite, while a neutral or acid pH favors the formation of marcasite. The latter is unstable in contact with air and highly sensitive to humidity, which inevitably causes marcasite samples to weather, transforming them into ferric sulfate and sulfuric acid. To slow down this phenomenon, it is possible to apply a specific varnish to the sample, but this only delays the process. Mineralogy specialists, whose collections are old, have observed that this chemical reaction also alters boxes and labels exposed near minerals degraded to sulfate.

Marcassite stone can be found in the form of nodules, boudins or mamelonned kidneys, which are enveloped by a goethite iron cap, resulting from an oxidation phenomenon. Sometimes, the alteration is so severe that pseudomorphosis occurs, with goethite replacing marcasite entirely. If the nodules are fragmented, they reveal an aggregate of needle-like crystals organized into rays (fibroradial structure) that have a pewter-white luster, but raPidly tarnish on contact with air. The stone is rarely found as isolated crystals, but when it is, it has a silvery-metallic luster and an elongated, tabular appearance, more rarely prismatic. The crystals form a complex array of multiple macles with a so-called “cock’s crest” or “arrowhead” arrangement, with other thinner crystals lying parallel to these macles.

The main deposits of marcasite stone are in South and Central America (Peru, Bolivia, Mexico), Europe (Spain, Romania, Sweden) and the USA. In the past, its rich ferric disulfide content made it an essential element in sulfuric acid production.

WHERE DOES THE NAME MARCASSITE COME FROM?

The name “marcasite” probably comes from the Arabic “marqachita”, meaning “pyrite”. Indeed, marcasite is a crystalline form of pyrite, a stone that is often confused with marcasite. However, although the two stones are similar, they differ in their atomic structure and physical properties. It’s also interesting to note that the term “marcassite” has been used in the past to refer to other sulfide minerals, but is now generally reserved for the crystalline form of pyrite.

WHICH CHAKRA DOES MARCASSITE ACT ON?

Marcasite is often associated with the solar plexus chakra, which is located in the abdomen area. This chakra is linked to self-confidence, willpower, inner strength and digestion. Marcasite is considered a stone that can help balance and stimulate the solar plexus chakra, promoting self-confidence and decision-making. It can also help regulate digestion and relieve stomach upsets linked to stress and anxiety.

What’s more, marcasite is also associated with the planet Mars, which is the planet governing the sign of Aries.

SUMMARY OF THE MARCASSITE STONE

Marcassite stone is a semi-precious stone that is often used in jewelry making. It is composed of iron sulfide and has a shiny metallic appearance. Marcasite is often confused with pyrite due to their similar appearance, although pyrite is harder and denser than marcasite. Marcasite stone has been used since antiquity to make jewelry and ornaments. It enjoyed a period of great popularity in the 18th century, but has since become less common due to its tendency to tarnish over time. Marcasite jewelry often requires regular maintenance to preserve its brilliant appearance. Marcasite is also used in gemmotherapy for its alleged healing properties.
