Exquisite beauty, bewitching, unique patterns - this is natural agate, a semi-precious mineral. It is not surprising that gemstones are increasingly being counterfeited, “improved” - tinted, painted, irradiated. This destroys the magical and healing properties of natural stone. How to distinguish natural agate from imitation can be found in this article.

HOW TO DISTINGUISH A GENUINE AGATE FROM A FAKE
Real agate or fake can be determined in different ways. There are instrumental methods that are not available to the average buyer. These include:
- Chelsea filter. Under it, blue and green agates will glow with a pinkish light.
- Fluorescence color: pale, yellowish, greenish. Agate practically does not fluoresce; if the stone being analyzed cheerfully and actively fluoresces in other colors, then it is a fake.
- Examination of the sample under a microscope. Here, almost all the secrets of the fakes are in full view. The mineral is not monolithic; it has cracks and voids. And the coloring solutions that fill cracks are clearly visible under a microscope.
Sarder
If you don’t have a microscope and fluorometer in your bag, you can use your eyes, hands and knowledge from our article.
Thermal conductivity
Natural minerals have low thermal conductivity.
- A fake made of epoxy resins, plastic or glass will heat up very quickly in the palm of your hand, within 5-7 seconds.
- A natural gem will require at least half a minute to heat up.
Hardness
The strength test will help in identifying fake stone chips.
You can take a sewing needle and scratch the gem.
This method works especially well when checking a bead, where you need to “poke” with a needle next to the hole in the bead.
- The mass pressed from crumbs will crumble when pressed or scratched.
- Natural agate will withstand “attack”.
Chrysoprase
Color fastness
Painted stones are brought to clean water... with water.
- Dip the gem halfway into the water.
- Let him stay there for several hours.
- During this time, the water will wash away the paint that was used to tint the gem.
- If it has been painted, the water will become slightly cloudy after a few hours.
We study the difference between the dry and soaked parts of the stone.
On suspicion:
- difference in color of the parts being tested;
- the shine of the “soaked” half - natural agate will not change its shine;
- The color of the stone has faded or become cloudy - this means that you are holding a fake.
The natural gem, after drying, will be the same as before testing.

Shine
The natural mineral has a soft matte shine.
In your hand, the glassy shine of the stone pleases the eye - don’t be fooled, this is not an agate, but a tinted gem, “killed” by treatment with chemically aggressive solutions.
Color
Often, ordinary natural gray stones are impregnated with solutions of salts of chromium, cobalt, iron, nickel and other metals. The process is combined with annealing or treatment with acids or alkalis.
Expected color | What and how to process |
Blue (cyan) | The mineral is placed in a solution of yellow blood salt, then boiled in a solution of iron sulfate. |
Black | The gem is kept in a concentrated sugar solution, then treated with sulfuric acid. Cobalt nitrate is sometimes used. |
Brown (imitation sarder) | Methods for obtaining black stone vary. |
Green | Impregnation of the mineral with solutions of chromium salts or nickel nitrate followed by firing. |
Red | The gem is treated with a solution of iron nitrate and then fired. |
African agate
(firing - high heat).
To enhance color, natural stone is subjected to ionizing radiation.
If:
- layers are too contrasting, sharp transitions between stripes;
- solid color, without stripes or lines (even subtle ones);
- too bright, unnatural colors -
It is better to refuse the purchase - this is clearly processed agate that has lost its healing and magical properties; it cannot be called natural.
Cracks
“African agate”, “dragon veins”, “craquele” are not varieties of gemstones. The names are derived from the processing method.
- Natural agate is tinted (painted), then heated strongly and immediately cooled sharply. This causes dark cracks that look like veins to appear in the stone. These varieties are called "craquele", or "dragon veins".
- Natural craquel exists, but is vanishingly rare.
- If the gem is first heated and cooled, and then painted, the veins remain light, but the stone darkens. This is an “African” agate, no longer a natural specimen.
Black agate ring
Uniformity
- A natural mineral always contains layers, even if they are invisible to the naked eye.
- Even in a black specimen (if it is natural), reddish, gray, and white layers are visible under a magnifying glass. It is impossible to fake them.
Agate is a layered stone: this is its “calling card”.
Certificates
- There are no state-issued certificates for semi-precious stones.
- There are organizations that can issue a so-called certificate (according to their own standards). Naturally, without an expert opinion, this is just a piece of paper.
- All that can legally support the naturalness and properties of a stone is an expert opinion from a gemological laboratory. However, you will have to pay for it. Often more than the stone itself is worth.
Who is it suitable for?
But, not everything is so simple - black agate, like any other mineral, has its own meaning. Therefore, it is not suitable for everyone, and esotericism clearly indicates the compatibility of the mineral with different zodiac signs, human psychotypes and names.
Zodiac sign
Black agate is ideal for Taurus. It is to this constellation that he promises protection and prosperity.
It also goes quite well with the following constellations:
- For fish it will support health.
- For virgins, it will be an excellent amulet for maintaining a psycho-emotional state.
- For Libra, it will bring peace and tranquility to the family. But it is important to respect the mineral and try to display it in a prominent place in your home or wear it as an elegant item on your body. Libra should try to place it as close to the heart as possible.
- For cancer it will help get rid of negative outside influences.
- Scorpios and Geminis can also use it as a talisman.
Note! But for Sagittarius and Aries this mineral is strictly contraindicated. He is an antagonist towards people born under these constellations.
But for Capricorn it is a neutral mineral, which, although it can be used, is not worth expecting from it to have an intense effect on fate.
By name
Women with the following names can actively use the stone in different types of jewelry or amulets:
- Agatha.
- Taisiya.

- Thin-banded agate (0.5-1 mm);
- Broadband agate (from 1 mm);
- Rough banded agate (from 10 mm);
- Variegated agate (from 0.5 mm to 10 mm).
According to the drawings there are agates:
- Bastion - patterns resemble old maps;
- Ocellar layers are concentric, forming a pattern resembling an eye;
- Dendritic - have tree-like or fern-like patterns;
- Moss – the pattern looks like moss thickets;
- Landscape - with intricate patterns;
- Iridescent or iridescent;

Based on the color of the layers, they are distinguished:
- Carneolonyx (red and white);
- Sardonyx (brown and white);
- Arabic onyxes (black and white);
- Chalcedonyx (bluish-gray and white).
Colors
The most common are light-colored agates with alternating blue-gray, white, and colorless layers.
Stones with yellow, brown, red, black layers are not so common, but bright green or blue colors in this mineral are very rare. Certain color varieties of agate even received their own names, for example, onyx consists of plane-parallel layers of various shades, and red and red-brown agate is called sardonyx.
Tibetan Dzi beads
Dzi beads are agate with a pattern printed on it: various circles, waves, geometric shapes. A bead with the so-called “9 eyes” is especially valued. This number is sacred in Buddhism. Their history goes back about three thousand years.
Tibet and everything that is made there is considered sacred. These beads were used as amulets that gave strength and brought good luck. Alexander the Great gave them to his soldiers as a talisman for good luck in battle. Today they are famous all over the world and are worn by many celebrities in the form of bracelets.
Tibetans make beads from blue agate. In addition to agate, the ancient beads included minerals that do not exist on earth. They were attributed to alien origin. How our ancestors made these beads is unknown to this day.
Areas of use
The main area of application of black agate is jewelry. Most often it is worn in the form of necklaces or pendants. Men's signet rings made from this stone look impressive and elegant. The best examples of jewelry are kept for centuries, becoming the pride of rich families.
The most powerful energy of the gem is used by lithotherapists. Black agate can help a person improve their health and get rid of mental trauma. Magicians of our time, like their Celtic and Roman predecessors, use the gem in their rituals.
Unlike other varieties of agate, coal-black stone is not used as an ornamental material. This gem is too rare and expensive to be “ruined” by complex processing.
History of the stone
Black agate stone was already known in antiquity. In ancient India, it was considered a talisman of gurus and spiritual teachers; the gem symbolized wisdom and the ability to lead others. It was believed that the stone was capable of granting enlightenment, magical abilities, and helping to achieve spiritual perfection.
In ancient Rome, they tried to ensure a good harvest with the help of the mineral. Peasants buried it in the fields before starting plowing. Perhaps the Romans learned about this stone from the Celts or Etruscans.
In Ireland and Britain, Druids also invoked fertility by marking the mineral with sacred symbols.
In the Middle Ages, another property of the stone was discovered. Merchants, warriors, and pilgrims, going on long journeys, bought black agate for their wives so that they would not forget them. He helped maintain fidelity during a long separation.
Western European doctors advised the mineral to pregnant women so that they could give birth to a healthy baby. A pendant with a gem also helped nursing mothers - the milk did not run out, and the breasts did not become inflamed.
Chemical, physical properties
Black agate is characterized by: increased hardness, opacity and layered structure. Manganese adds depth to the color and mineral. The stone has a layered structure formed by silica, chalcedony, quartzite and quartz. The matte deep color of this mineral is given by the large proportion of manganese in its composition.
Formula | SiO2 (silica) |
Color | Black |
Shine | Matte |
Transparency | Not transparent |
Hardness | 6,5—7 |
Cleavage | absent |
Kink | uneven, conchoidal |
Density | 2.6 g/cm³ |
Talismans and amulets
As a talisman, agate helps the owner discover deception, identify ill-wishers, and warns of impending troubles. The mineral tunes its owner to the wave of perception of the subtle world, makes him clairaudient, clairvoyant and clairvoyant. However, those who wish to achieve unconventional abilities should remember that they will be able to achieve them with the help of agate only if they learn to understand the “speech” of the stone
You can study the language of a mineral (not only agate, but any other) if you focus all your attention on the stone for 10-15 minutes every day, thus establishing contact with it. When contact is established (when contemplating the stone, clear pictures will appear, for example, a river, a tree, a building, etc.), you can begin to work with agate, developing psychic abilities
Products made from agate have been known since ancient times: in tombs near Alushta (agate beads - 5th century BC).
