Cracking the Code: How to Identify Genuine Malachite and Moldavite Stones


Malachite and

Moldavite: How to Identify Real Stones

Natural stones have been sought after for centuries for their beauty, spiritual properties, and healing abilities. However, not all stones are created equal and it can be challenging to differentiate natural stones from synthetic or imitation stones.

In this article, we delve into two popular stones – malachite and moldavite – and provide tips on identifying genuine stones.


Malachite is a striking green banded stone that is a favorite among lapidaries. It is a copper-bearing stone that has been used for centuries for its healing properties.

It is associated with transformation, protection, and emotional balance.

Description and Properties

Malachite is a botryoidal stone, which means it forms in globular groups. It often occurs with another copper-bearing stone, azurite, and the combination of the two creates a distinctive blue-green color.

Malachite is easily recognizable for its green, banded appearance that resembles the layers of an onion. It is a soft stone with a Mohs scale rating of 3.5-4.

Forms and Associations

Malachite is often found in its botryoidal form, which is highly prized for its beauty. It is also frequently associated with copper deposits.

You can find malachite in a range of jewelry, statues, and decorative objects.

Identifying Fakes

Unfortunately, malachite is a popular stone for people who want to create fake stones for profit. There are several ways to identify fake malachite, including resin fabrications, reconstituted malachite, and heat tests.

Resin fabrications involve creating a fake stone by mixing resin with small amounts of genuine malachite powder. Reconstituted malachite involves mixing malachite powder with other minerals or resins to create a more durable stone.

A heat test can identify fake malachite because genuine malachite will break down under high heat. Genuine malachite should have clean patterns and bright colors.

Be cautious of malachite that is sold at a low cost.


Moldavite is a unique green tektite that is formed from flung sand during a meteorite impact. It is a highly sought-after stone for its rarity, beauty, and mystical properties.

It is associated with spiritual growth, transformation, and enlightenment.

Description and Properties

Moldavite is a green glass-like stone that is usually found in irregular chunks. It has a transparent appearance and is often described as having a bubbly texture.

Moldavite is thin at one end, where it is believed to have been formed when the meteorite hit the earth. It has a Mohs scale rating of 5.5-6.

Identifying Characteristics

Moldavite can be identified by its unique color and texture. It is usually sold in irregular chunks and has a thinner end.

Genuine moldavite is also often more expensive than other stones due to its rarity and natural properties.

Identifying Fakes

Unfortunately, there are many fake moldavite stones on the market. Fake moldavite can be larger than a dime and have good color and a bubbly texture, but it may lack the irregular shape and thinner end of genuine moldavite.

Be wary of moldavite that is reasonably priced or comes in specialty molds. It is also essential to identify unreliable ID for authenticity and be cautious of stones sold at exceptionally high prices.


Identifying genuine natural stones can be challenging, and it requires some knowledge and research. If you are in doubt about the authenticity of a stone, it is always best to consult with a reputable gemologist or stone expert.

Knowing how to identify genuine stones ensures that you invest in a valuable and beautiful stone that is not only aesthetically pleasing but also has spiritual and healing properties.

Malachite vs.


Differences and

Similarities in Identifying Real Stones

Identifying genuine natural stones can be challenging, especially in a market inundated by imitation products.

Two of the most popular stones,

Malachite and

Moldavite, are often faked by unscrupulous dealers. In this article, we will compare and contrast these two gemstones, highlighting their similarities, differences, and tips on identifying real ones.


The most obvious similarity between these two stones is that they are both easily faked.

Malachite and

Moldavite imitations can be made using resins, other minerals, or heat and pressure treatments.

These imitations are then made to look like genuine stones and sold at a fraction of the cost. Because of this, it is essential to purchase stones from reputable dealers or accredited gemologists.


Malachite and

Moldavite are fundamentally different in their physical and chemical composition.

Malachite is a copper-bearing stone that is opaque and characterized by its green, banded appearance.

Moldavite, on the other hand, is a tektite formed from flung silica-based sand during a meteorite impact. It is transparent and has an irregular bubbly texture.

Physical Characteristics

Malachite has a Mohs hardness rating of 3.5-4 and has a banded or layered appearance. It is available in polished and smooth surfaces or rough and unpolished surfaces.

The beauty of

Malachite can be appreciated in decorative objects, statues, and jewelry pieces.

Moldavite, on the other hand, has a Mohs hardness rating of 5.5-6 and has an irregular chunk shape. It is transparent, glass-like, and has an irregular bubbly texture.

Chemical Composition

Malachite is a copper carbonate hydroxide mineral and is also associated with other copper-bearing stones such as azurite, chalcopyrite, and bornite. Due to its copper content, the stone is highly coveted by jewelry makers and lapidaries for its unique green color.

Moldavite, on the other hand, is a tektite formed from the impact of meteorites on the earth’s surface. It is composed of silicon dioxide, aluminum oxide, and other trace elements such as magnesium and iron.

The chemical composition of this stone is what gives it its unique color and texture.

Reliable ID

When it comes to identifying genuine stones,

Malachite has reliable methods of identification, while

Moldavite is not so straightforward. Real

Malachite should have clean patterns, bright colors, and be relatively soft, while synthetic stones will show signs of resin treatment or other cutting and polishing techniques.

Moldavite, however, is more difficult to verify due to the lack of a dependable identification process. Experts in the field recommend buying from reputable sources, purchasing from dealers who are members of accredited industry organizations like the International Gem Society or the Gemological Institute of America.

Another measure is to look for stones with certifications and reports, which indicate that they have passed the tests for authenticity.

Caution for Buyers

The market for natural stones is a gold mine for scammers who will do anything to make money. Unfortunately, unscrupulous dealers use fake gemstones made from less expensive materials to deceive their customers into believing they are acquiring genuine precious stones.

In conclusion, natural stones like

Malachite and

Moldavite offer beauty, spiritual, and healing properties to their users. While fake imitations can be easily purchased at a lower price, identifying genuine ones is important not only for the value of the purchase but also for the authenticity of the properties.

So when buying these stones, it is best to practice caution and buy from reputable sources to ensure their authenticity. In conclusion, identifying genuine

Malachite and

Moldavite stones requires knowledge and discernment.

While there are methods available to identify genuine stones, it is always best to buy from reputable sources and accredited professionals. Due diligence in purchasing natural stones ensures that the buyers acquire genuine stones that offer value and authentic benefits.
