Traditionally the name ‘Peacock Ore’ was used to describe bornite, named for the classic iridescent sheen. Commercially for many years ‘Peacock Ore’ has been ‘faked’ by treating chalcopyrite with acid to produce a thin oxidized layer that has similar iridescent appearance to bornite. The iridescence on both these minerals, and other sulphides, is probably due to various oxidative coatings of uncertain nature, a few microns in thickness.


Bornite that displays iridescence is considered to be rare and highly sought after by collectors and enthusiasts. The iridescence in bornite is caused by the thin layering of copper sulphide minerals that make up the crystal structure, which diffracts light and creates a rainbow-like effect of colours that shimmer and change as the angle of observation changes. This iridescence is often referred to as Peacock Ore due to the resemblance to the feathers of a peacock. While bornite itself is not necessarily rare, specimens that exhibit this striking iridescence are uncommon and can command high prices on the market. It is this OG Peacock Ore that we will discuss herein.

Peacock Ore, also known as the tarnish on Bornite. It is a strikingly beautiful mineral that is highly sought after by collectors and crystal enthusiasts. With its iridescent shades of purple, blue, and green, it has become one of the most popular decorative minerals in the world. Let’s dive into some interesting facts about Peacock Ore.

What mine locations produce the best quality: Bornite, also known as (Peacock Ore ~ Only when tarnished), is a copper iron sulphide mineral that is typically found in hydrothermal veins and contact metamorphic zones. It is widely distributed around the world and can be found in many countries, including the United States, Mexico, Canada, Australia, Peru, Chile, Morocco, and Germany, among others. Some of the most notable deposits of bornite are found in the Butte district of Montana, USA, and in the Kryvyi Rih region of Ukraine. However, not all bornite deposits exhibit the striking iridescence that is highly valued by collectors. The iridescent variety of bornite is considered to be relatively rare and is often found in smaller quantities compared to non-iridescent bornite.

Rarity: Peacock Ore is considered a relatively rare mineral, with crystal formations being particularly rare. It is valued for its distinctive colour and metallic sheen, which is created by a thin layer of oxidation on the surface of the crystal.

What minerals make up this crystal: The chemical composition of peacock ore, also known as bornite, is a copper iron sulphide mineral with the chemical formula Cu5FeS4. This means that it contains copper (Cu), iron (Fe), and sulphur (S) in its chemical makeup. The exact proportions of these elements can vary slightly depending on the specific specimen, but the overall chemical composition remains the same. Additionally, small amounts of other elements such as silver, gold, and platinum may also be present in some specimens of bornite.

Range of Colours: Peacock Ore has a range of iridescent colours, including shades of purple, blue, and green, which are produced by a thin layer of oxidation on the surface of the mineral. In some specimens, the colours may be more muted or include hints of gold or pink.

Historical Use: Peacock Ore has been used for decorative purposes since ancient times. It was first described by the mineralogist Ignaz von Born in 1725 and was named in his honour. Native American tribes used it for ornamental purposes, and it was also used in traditional Chinese medicine.

Lightworkers Use: Peacock Ore is believed to be a powerful energy cleanser and amplifier that can help to remove negative energies and increase positivity. It is said to enhance creativity, self-expression, and intuition and to promote physical healing and overall well-being.

Spiritual Benefits: In spiritual practices, Peacock Ore is associated with the third eye chakra and is believed to help with spiritual awakening and communication with higher realms. It is also believed to help with manifestation, abundance, and attracting good luck and fortune.

Metaphysical Uses: Peacock Ore is commonly used in crystal healing practices to support physical healing and relieve pain, particularly related to arthritis and other joint issues. It is also believed to help with circulation and the immune system.

Feng Shui Use: In Feng Shui, Peacock Ore is used to promote abundance and prosperity in the home or workplace. It is believed to enhance creativity and support the flow of energy in the space, particularly in areas related to career and finances.

Peacock Ore (Bornite) is a beautiful and powerful mineral that offers a range of spiritual, metaphysical, and physical benefits. Its vibrant colours and unique properties make it a must-have for any crystal collection or decorative display.


Peacock Ore and Chalcopyrite are often confused with each other, as they both have a similar metallic iridescence and are sometimes referred to by the same name. However, they are two different minerals with distinct properties and chemical compositions.

Peacock Ore is actually a trade name for Bornite, which is a copper iron sulphide mineral with the chemical formula Cu5FeS4. It is named after the mineralogist Ignaz von Born, who first described it in 1725. Bornite has a more colourful iridescence than Chalcopyrite, with shades of purple, blue, and green.

Chalcopyrite, on the other hand, is a copper iron sulphide mineral with the chemical formula CuFeS2. It has a golden yellow to brass yellow colour with a metallic Luster, and its iridescence ranges from blue, purple, and green to gold and pink.

While Peacock Ore (Bornite) and Chalcopyrite are both copper sulphide minerals, they have different chemical compositions and crystal structures. So, it’s important to differentiate between them to ensure you are getting the right mineral for your intended use.

There are several ways for Chalcopyrite to get treated to look like the rare Peacock Ore:

  1. Heating: Chalcopyrite can be heated to high temperatures in a controlled environment to produce a rainbow of colours on its surface. The process is known as heat-treating or annealing, and it can cause the chalcopyrite to develop a brighter and more vivid iridescence.
  2. Acid treatment: Chalcopyrite can be treated with an acid solution to remove the outer layer of the mineral, which can expose fresh surfaces that will display different colours. The acid treatment can be combined with heat treatment to produce more dramatic results.
  3. Electroplating: Chalcopyrite can be electroplated with a thin layer of metal, such as gold or silver, to create a metallic sheen on its surface. The electroplating process can also create a protective layer on the mineral that will prevent it from tarnishing or corroding.
  4. Chemical treatment: Chalcopyrite can be treated with a chemical solution that will oxidize the mineral’s surface, causing it to develop a range of colours. The chemical treatment can be combined with heat treatment to produce more vibrant colours.

It is important to note that crystal healing and other alternative therapies are not intended to replace professional medical treatment. While some people may find benefit from using crystals for healing purposes, they should not be considered a substitute for medical advice, diagnosis, or treatment.
