Natural agates and onyxes are not monochromatic. They always have a drawing on them. It can be seen under a microscope when examined using special methods. Black agate also has inclusions and stripes, even if they are not visible to the naked eye. Gemologists call dark gray chalcedony black agate; black onyx - experts do not recognize this name.
ONYX AND AGATE: WHAT IS THE DIFFERENCE
For non-specialists, it is acceptable to think that onyx and agate are one and the same.
In essence, these are twin brothers: both belong to layered chalcedony, the same hardness and resistance to acids. They have the same chemical formula, SiO2. The main difference between black (relatively) onyx and black agate is in the patterns and contrast of layers.
Minerals also differ in the quality of their shine. Agate has a matte sheen, while onyx has a glassy sheen.
These minerals are distinguished by the arrangement of stripes:
- onyx stripes are usually straight, thin, and run parallel to each other;
- agate has thicker stripes, often concentric, parallel or oval-shaped.
Onyx
Onyxes are more expensive than agates, which is surprising - the stones are almost the same. True, the hardness of onyx is higher, and the lines-stripes are thinner and more graceful than those of their counterparts.
Types of minerals
Agates amaze with their variety of patterns: most often they are found in gray, blue, and white stripes.
Stones with stripes of other colors have their own names:
- bastion;
- mosses;
- ocellar;
- landscape;
- black;
- iridescent.
Onyx in orange, red, fiery colors is called sardonyx. This mineral is called Algerian, if it is painted in black and white colors, it is the most expensive of the onyxes.

Samples of dark deep shades are found: they are usually called black. But black onyx does not exist: this is a trade name, there is no such concept in gemology.
Black agate
Onyxes are easily converted to slate black by refining with cobalt nitrate. In ancient times, this procedure was carried out using honey and heated sulfuric acid.
Treated stones are not fake.

One of the advantages of colored onyx is that it is suitable for almost all representatives of the zodiac cycle, only the color varies.
The red variety or sardonyx is the best stone for bright emotional personalities, channeling their irrepressible ardor in the right direction. This is a talisman of Aries, signs of the fire element; it is better if it is a ball or a carved figurine of an eagle. Black stone is contraindicated for Aries (any kind). Recommended for Capricorns, especially in the form of an amulet with a figurine of a black cat, as well as for Taurus, Libra and Virgo (namely black color).

Therefore, you can safely give a souvenir or chess, an amulet or jewelry with this stone even to that person whose zodiac sign is not known.
How to spot a fake
Onyx is a hard stone with the properties of expensive stones, although it is classified as semi-precious or ornamental gems. High hardness leaves no chance of leaving damage on it.
Helpful advice! If you doubt that you have purchased beads from this stone, swipe it with a knife or any hard blade - there will be no scratches or other marks left.
Counterfeits made of colored glass are often passed off as onyx, sold to unlucky tourists and visitors to oriental bazaars at the price of natural stone. A natural gem does not heat up well, so it often has a lower temperature than the surrounding environment.
Looking at how a mineral looks in a photo, it is easy to recognize characteristic stripes and veins - natural stones do not have sharp boundaries between color segments. Contrasting transitions and multi-colored stripes without related shades are most likely a fake.
Note! Sometimes cheaper stones are impregnated with caustic green or red-brown dyes to add brightness. Such beads and pendants quickly fade, so sellers do not hang them on the counters on the sunny side of the market.
In interior design, they do not hide the fact that imitation glass, acrylic or onyx-like porcelain stoneware is used. This is a beautiful decor in the form of countertops and facing tiles.
