What does chalcopyrite stone look like?
Chalcopyrite is a stone that is striking in its external resemblance to gold (it is sometimes actually present in it in the form of small chips). The mineral is popularly known as fool’s gold or copper pyrite. It is common, so it is cheap, but jewelry with it looks very original. The magical properties of chalcopyrite allow it to be used as a home amulet.
Story. Origin
- fool’s gold;
- donkey gold;
- false gold;
- golden trick.
The official mineralogical name of the stone – chalcopyrite – appeared 300 years ago . “Chalkos” is translated from ancient Greek as “copper”; “Pyrite” is the name of a mineral that is similar in composition.
Copper pyrite is of hydrothermal origin. Also formed during metamorphic processes, found in skarns and greisens.
The chemical formula of chalcopyrite and its composition, in which sulfur and copper are almost equal, give grounds to classify this mineral as copper-sulfur pyrite. It is the most important copper ore, and in the form of crystals it is a valuable collectible mineral.
Physico-chemical properties of chalcopyrite
- Chemical formula – CuFeS2 .
- Color – golden yellow, reminiscent of red gold; sometimes greenish, blue, yellow. There are variegated and almost black specimens.
- The shine is metallic.
- Transparency – opaque.
- Hardness – 3,5 – 4 Feet .
- Density – 4,10 – 4,31 g/ cm 3 .
Chalcopyrite belongs to the group of pyrites.
Large crystals are rarely found. They have a distorted tetrahedral appearance. Deep, coarse shading is usually visible on the edges. Characteristic is a bright mottled tarnish on chips and the surface of crystals.
Twinning and twin germination are common.
The mineral forms granular aggregates, dissemination, and veinlets in sulfides.
Fragile. It is easy to scratch with a sharp object.
Melting temperature – 1000 o C . Under a blowpipe, the carbon is fused into a gray-black magnetic bead.
Has high electrical conductivity.
It dissolves in sulfuric acid with the release of sulfur, and is resistant to hydrochloric acid.
If chalcopyrite is constantly exposed to air, it will turn into malachite after hundreds of years.
Place of Birth
Chalcopyrite has been found on almost all continents, but only in other rocks. The pure mineral has not been found; it is found only in the form of intergrowths with quartz or chrysolite druses.
In each deposit, the ore differs in quality and properties:
- Russia. Greenish stones are mined on the Kola Peninsula and the Urals. In the vicinity of Norilsk, raw materials are very “contaminated” with impurities, so their extraction is unprofitable.
- Kazakhstan. In the Dzhezkazgan area, small agglomerates are mined.
- Japan. On the island of Honshu, small crystals are found, fused together in the form of pyramids.
- France. Mineral suitable for jewelry making. The most expensive one looks like gold.
- Mexico. Small stones are mined in the Zacatecas area.
- South America. Aggregates of copper pyrite form intergrowths with sphalerite.
The size of the largest chalcopyrite crystals is more than half a meter. Such specimens are mined in the Urals.
Application of chalcopyrite
The areas of use of copper pyrite are industry, jewelry and collecting.
Industrials
Chalcopyrite is used as a source for obtaining copper and beneficiating ores (copper-zinc, etc.). Copper in this mineral makes up only a third, but the process is profitable due to the availability of mining, the shallow occurrence of the mineral and the abundance of its deposits.
Before the advent of vacuum tubes, chalcopyrite was used as a detector in early radio receivers.
Jewelcrafting
Chalcopyrite is an ornamental stone; it is not easy for jewelers to process it, as it is quite fragile. Jewelry companies do not use this mineral due to its cheapness and problematic processing. Jewelry with copper pyrite is mainly created by single craftsmen. They make rings, pendants, earrings. The frames are often used in inexpensive metals: bronze, brass, cupronickel, jewelry alloy. Sometimes the frame is made of silver.
Chalcopyrite from France is of particular importance to craftsmen and consumers as it appears like gold due to its rich golden tone and soft glow.
Collecting
Collectors appreciate samples with tarnish, as well as textured ribbed edges. Multi-colored variegated fragments with rock protrusions on the surface are also in demand.

Medicinal properties
Before using this mineral in powder form or as an ingredient in an ointment, you should consult your doctor. If he recommends the use of chalcopyrite, he will prescribe a suitable dosage. The dose should not be increased, as in this case an allergic reaction is possible.
Lithotherapists have discovered some healing properties of chalcopyrite:
- Anti-inflammatory, antimicrobial effect. A stone crushed to powder is added to a pharmaceutical ointment and lubricated on the skin for dermatitis, eczema, etc.
- Calming effect. For systematic insomnia, anxiety, depression, take orally a mixture of ingredients ground to powder: mineral, chalk, sugar.
- Stimulates the production of gastric juice, improves appetite.
Not everyone can use chalcopyrite for medicinal purposes, especially taking it orally, since copper, sulfur, and iron can cause problems, for example, increasing the production of bile. If you decide to be treated with this mineral, you should consult a doctor.

How to wear and care
This mineral has great natural power, so you cannot carry it on yourself or with you all the time. Enough once in two weeks show off this decoration in front of people and put it away until next time.
If a person experiences discomfort while wearing a stone, they should limit contact with it and wear it only in difficult situations.
Chalcopyrite is not particularly durable and therefore requires delicate handling:
- Jewelry containing this mineral should be stored separately from other jewelry.
- It is better to place collectible samples in a closed glass container to slow down the oxidation of the stone.
The oxide film that appears on the surface should be carefully removed with a soft cloth. This must be done regularly, otherwise the film will be difficult to remove.
How to distinguish from fakes
Sometimes chalcopyrite is falsified. Counterfeits are made of coated glass or plastic. It is easy to distinguish them from natural stone:
- If you scratch the sample with your fingernail, the coating on the glass will be damaged.
- If you run the mineral over a light, hard surface, it will leave a greenish-black mark.
- Natural stone is opaque, impenetrable to light, so you need to look through the sample into the light.
- Compared to fakes, jewelry made from copper pyrites looks rough, but interesting. The mineral cannot be processed gracefully. It is usually used to make beads, cabochons or figures with simple geometric shapes.
Chalcopyrite can be distinguished from pyrite by color: the former has a more intense yellow color.
Price
Chalcopyrite is not a very expensive mineral:
- The cost of collectible samples starts from 400–500 rubles .
- Prices for jewelry largely depend on the material of the frame. If it is a jewelry alloy, cupronickel, bronze or brass, then the price for the jewelry usually does not exceed a couple of thousand rubles . Products set in 925 silver are more valuable.
The most expensive chalcopyrite comes from France. Its soft glow and rich golden tone makes it look like gold.
Chalcopyrite (copper pyrite) is a soft stone related to minerals. Under natural conditions, it is often found in mines. Jewelers prefer not to make jewelry with this mineral. The fact is that although copper pyrite is beautiful, the metal that is part of the gem quickly enters into a chemical reaction with atmospheric oxygen.
Therefore, jewelry with chalcopyrite quickly oxidizes, becomes covered with a film, which worsens their appearance. The stone itself is brittle and breaks easily.
History of origin
Chalcopyrite is not a precious, but an ornamental stone. This mineral has been mined for more than two millennia – even before our era, people developed deposits of copper and tin, where they found this mineral.
And copper deposits are the most widespread on earth. This gem has been called differently over the centuries, but one name remains common – copper pyrite. But there are other names:
- donkey gold;
- Fool’s gold
This copper gem received its name three centuries ago. The basis was taken from the Greek translation of the name of the metal – chalcos.
Place of Birth
Chalcopyrite is found commercially everywhere. Chalcopyrite is mined in mines, where there are many polymetallic formations and copper-nickel ores.
The largest crystals of this mineral, mined in mines, are more than 50 cm. Such large stones are mined in deposits located in the Urals and in Puyva.
Small-sized chalcopyrite stones are mined:
- in Zhezkazgan (Kazakhstan);
- on the island of Honshu;
- in Isère (France);
- Zacatecas (in Mexico);
- In the south of Australia.
Chalcopyrite is often combined into a common rock with quartz and chrysolite druses. And subsequently this rock has to be broken into pieces in order to separate the minerals from each other.
Places of extraction of various types of this mineral:
- calcite deposits are rich in small crystals of copper pyrite;
- in the Berezovsky mines in the Ural Mountains, green stones are found;
- in the deposits of the Japanese islands, there are many crystals with a pyramidal structure;
- in mines located in the countries of South America, ores of copper pyrite and falerite are found;
- In Norilsk, copper pyrite is mined, which contains many admixtures of other metals. The extraction of this mineral in these mines is considered unprofitable.
The most expensive are the minerals mined in the deposits of France. It has a beautiful golden hue, very rich in tone, and its glow is soft and pleasant. Such stones are valued very highly in the world market.

- silver inclusions;
- golden crumb;
- impurities of other precious metals.
Chalcopyrite can only be dissolved in sulfuric acid (sulfur precipitates during this reaction). But this mineral is insoluble in hydrochloric acid.
When interacting with air, another ornamental stone is obtained – malachite. But such a process is long and can take centuries. The mineral is widely used in industry, where its decomposition produces pure copper.
Medicinal properties

- improve night sleep;
- help with nervous exhaustion or constant stress.
In the process of wearing jewelry with this healing stone, bile production increases. But doctors believe that copper pyrite can provoke an allergy.
Magical properties
The magical and astrological properties of this gem have not yet been fully understood, so it is difficult to say how strong the magical properties of Chalcopyrite are. But in many countries, copper pyrite is considered a fairly strong amulet. This gem is used to create amulets.
In Europe, copper pyrite is considered the magic stone of women:
- by regularly meditating with him, women find their “soul mate”;

Jewelry with mineral
Among jewelers, the mineral is not very popular because of its fragility. But some jewelers still use the gem when making earrings, bracelets, pendants. The stone is cut cabochon and then set in a silver setting. The mineral does not combine well with gold.
Raznovydnost
The color of the gem can be varied from greenish and blue to variegated. And the color depends on the amount of impurities in the copper pyrite. There are yellow minerals (they are called donkey gold).
If there is a sufficient amount of black coal among the impurities, then the color of the gem will be close to black (such a nugget is called a “magnetic bead”).
How to distinguish a fake?
To distinguish Chalcopyrite from a fake, you should know what a natural gem looks like, since a fake, even a very skillful one, will not have all the hallmarks of copper pyrite.
Copper pyrite has a characteristic shade of green, shines quite dimly, and the reflection is two times less than that of gold. The mineral is not very durable, it is easy to break it into pieces.
You can determine the authenticity of the stone by passing it with any sharp object. If a trace of black with a greenish tint remains on it, this is copper pyrites, yellow color indicates that it is gold.
