Fake Malachite: How to Tell Real from Fake

Fake malachite is increasingly common, particularly online. Some imitations are easy to recognise, while others can be convincing enough to fool experienced dealers. This article explains how fake malachite is produced, the signs to look for and why price, provenance and claims made by sellers all matter.

Identifying Fake Malachite

Due to its popularity, fake malachite is often produced using coloured plastic or resin with distinctive green swirls that mimic the stone’s natural banding.

Real malachite is cool to the touch, as are most natural minerals. It has intricate, organic patterns and, being a copper mineral, is relatively heavy. Fake malachite is often lighter, feels warmer and has overly uniform or repetitive patterns.

The colour of real malachite ranges from light to dark green, with prominent banding or concentric circles. The banding may be extremely dark green, but it's not naturally jet black, which is a good indicator of a fake stone.

Black is used in the production of fake malachite because it’s extremely difficult to reproduce the stone’s natural colour.

Natural Forms of Malachite

Malachite is best known as a smooth, banded stone, but it also occurs in other formations. It can grow as a stalactite, a hanging formation shaped over time by mineral-rich water, and can also crystallise.

Crystallised malachite forms needle-like or prismatic crystals, often clustered together or growing alongside other copper minerals such as azurite.

Malachite can also occur in a fibrous form. This variety, known as velvet malachite, has a silky appearance due to its fine, hair-like crystals.

Fake Malachite Sold Online

Most fake malachite is produced in China. Some fake material is so convincing that it can be difficult to identify, particularly on sight alone, even for an expert.

The malachite in the following photo looks authentic, but is being sold in an online marketplace for £12.95, with free shipping from China. The seller states that the piece is ethically sourced. Shipping to the UK would cost more than the price of the stone.

Once the costs of mining, processing, and transportation between Africa and China are taken into account, claims of ethical and sustainable sourcing at this price become impossible to substantiate.

The malachite in the next photo, which also looks to be genuine, is being sold for £4.95, with free UK shipping. Both images have very obviously been digitally altered.

Testing Malachite for Authenticity

Fake polished malachite can be relatively easy to identify, but raw material can be far more difficult. Although there are tests that can confirm whether malachite is real or fake, most will cause some damage. Laboratory testing is another option and will not cause damage, but can be expensive.

Fake Malachite Can Fool Experienced Dealers

Some years ago, fake malachite stalactites were produced in Africa. The stones were made with a thin copper wire running through them, so when broken open, a hole ran through the centre.

A mineral dealer from the Democratic Republic of Congo, who had been around malachite his entire life, purchased a large quantity of this fake stalactitic material. Upon arriving at the mineral fair in Tucson, Arizona, he learned it was fake but nonetheless sold it as genuine.

How to Avoid Buying Fake Malachite

Buying from a knowledgeable and trustworthy seller is the best way to avoid fake malachite. Price may also be a good indicator. When material has genuinely been ethically mined, it's more expensive.

Ethically sourced crystals cost more because they require higher wages and safer working conditions, both of which incur additional expenses. Therefore, you can't realistically have cheap, ethically sourced stones.

In this industry, everyone wants crystals that have been ethically and sustainably sourced. However, few people are prepared to pay the additional price.

The malachite we currently have in stock was ethically sourced from the Democratic Republic of the Congo, which is reflected in its price. For that reason, it does not sell as quickly as cheaper malachite that we've had in the past.

When people pay more, they expect a higher grade, but ethical mining adds to the cost regardless of the grade.

Examples Found Online

In the photo below, the malachite in the top row is fake. The stones in the middle photo appear to be Kambaba Jasper.

The hearts in the first image in the second row are also fake. The malachite in the next two photos appears to be real, and the price, which is considerably higher, confirms that.

Having contacted the company selling the hearts, I asked whether the malachite was real. They confirmed that it was and told me the stone was imported from the Democratic Republic of Congo and the hearts were then produced in their factory in China.
