Description and properties of black coral, a rare mineral for fine jewelry

If you have ever worn jewelry with diamonds, you have probably noticed that wearing them makes you feel somehow different: more confident, stronger, more purposeful. In a word, you feel a little like the master of life, who can handle absolutely everything.

Perhaps this is self-hypnosis, but supporters of lithotherapy and occult sciences interpret such sensations differently. They believe that these magic stones are endowed with special magical properties that can influence human energy in both positive and negative ways.

Description of the stone

In Greek, “coral” means “son of the sea.” Essentially, this is the skeleton of a polyp. Black coral looks like a small bush with fluffy branches. The stone does not transmit light and has a waxy shine. The second name of the mineral is Akkabar.

The stone is shrouded in myths and beliefs:

  • When Perseus was able to cut off the head of the gorgon Medusa, the blood flowed in streams into the water, where it turned into coral;
  • the Romans used it to treat wounds, as an antidote to snake and insect bites;
  • in the Middle Ages it was a symbol of kindness, modesty, protection from evil spirits;
  • in Rus' it personified a happy family life and was given as a wedding gift.

Black coral grows very slowly at a depth of more than 100 m or in a cave or grotto - it does not tolerate the light of the sun. It needs a warm underwater current that carries its main food - plankton.

Diamond production technology

It takes several months of work for a diamond to shine with its 57 facets and become a real diamond. Processing technology has not changed for the last hundred years; the most modern cutting methods are certainly used, but the skill of the cutter plays a decisive role. Stages of obtaining diamonds from diamonds.

Grade

A pre-production assessment consists of a thorough examination of the stone through a lens; the appraiser looks at the size and mass of the mineral, identifies possible defects, and determines the structure of impurities. At this stage, the master understands what kind of diamond can be obtained from the crystal and how much it will weigh and cost.

Today, diamonds are evaluated by a program, the stone is placed in a spectral box, and the computer displays all the information about the stone in a matter of seconds, and the person makes the final decision.

Marking

After evaluating the nugget, markings are made - cutting lines are applied to the stone, which determine the shape of the future diamond.

Sawing

This is one of the most labor-intensive and difficult stages of work; due to the hardness of the stone, there is always a danger of cutting the diamond incorrectly and applying erroneous edges. If the stone does not need to be sawed into pieces, the craftsman carries out grinding, the operation removes excess parts of the stone and prepares the diamond for turning.

Turning and cutting

Diamond turning is a rather labor-intensive process during which the master gives the diamond its future shape. Cutting or applying facets (edges) is carried out by rubbing the diamond on a grinding disc.

First of all, the cutter works with the top of the workpiece, creating a platform on it (this manipulation is performed by removing a large, smooth bevel). After cutting, the lower part of the stone lends itself to forming a cone-shaped pavilion. The top facets will form the crown of the diamond. The cutter must also apply additional facets on the pavilion and crown. Each edge is sharpened at a certain angle. The almost finished diamond is also outlined with a girdle, and a culet (spike) running parallel to the platform is applied to the lower part of the pavilion.

Coral mining and processing

It is not widely distributed throughout the oceans and seas; the main production points are Cuba, the Red Sea, and India. Fishing is prohibited in many places.

Black coral is mined using 2 long beams with nets attached to the ends. Minerals are lifted, cleaned, and sorted by hand. Then the master cuts the stones into blanks and polishes them. Most often they do:

  • beads;
  • rose;
  • cabochon;
  • circle;
  • oval.

The final stage is soaking in a special solution for 36 hours to clean the surface and add shine.

How to distinguish from a fake

The quantity of black corals is limited, demand and price are high. On the jewelry market they give out the following for a stone:

  1. Fake. For imitation, colored glass, colored limestone or plastic are used.
  2. Artificial mineral. It has been produced since the 20s of the last century by burning calcite. Only a connoisseur can distinguish it from the original.
  3. Pressed coral. It is obtained by grinding substandard fragments into powder and then shaping them into a ball, oval, etc.

The following features will help you distinguish a real original from a fake:

  • glass fakes are heavy and cold;
  • limestone is easily scratched with a needle, leaving a white furrow;
  • when heated, plastic melts, emits a characteristic odor, and the natural mineral cracks;
  • prolonged exposure to water makes the natural mineral brighter;
  • the price of a fake is lower, the difference can be 10–30 times.

See what the stone looks like:

Diamond colors

Each stone mined from the depths of the earth has its own luminescence and color; most diamonds are yellow, but due to blue luminescence they are perceived by the human eye as transparent. “Pure water” diamonds are found in less than 1% of all mined diamonds; blue and black diamonds are even less common in nature.

Only stones with blue luminescence have jewelry quality. In this case, yellowness should be completely absent, but a slight brownish tint is allowed.

Color is a term used by diamond sorters and cutters. It means a slight shade, which determines whether the stone will become a diamond or will be used in industry.

Scientists do not fully understand how a diamond acquires its color. After all, there are no other chemical elements in the stone. The exception is black diamond, whose structure contains impurities of graphite, magnetite and hematite. Geologists believe that carbon receives its shades under the influence of radiation in the depths of the mantle; the higher the background, the more transparent the stone.

Properties and uses of coral

The formula of Akkabar is Ca(CO)3, based on calcium carbonate with admixtures of magnesium, iron, and manganese. Physicochemical characteristics:

  • hardness on the Mohs scale 3.5–4 points;
  • opaque;
  • density 1.3–2.6 g/cm3;
  • after processing it acquires a glass shine;
  • there is no crystalline base - the mineral is amorphous;
  • contains inclusions, pores;
  • decomposes under the influence of acids and high temperatures.

The main use of the stone is jewelry, souvenirs, and less commonly used in lithotherapy and magical practices.

Black coral is endowed with healing properties and is used for:

  • joint diseases;
  • neuroses;
  • migraine;
  • eye diseases;

Can you wear diamonds during the day?

Many people think that wearing diamonds is very easy. I put on the jewelry and went to show off in front of other people. But in our modern world, even on this score there are special rules.

Of course, no one will ever dare to call you an uncultured person if you do not adhere to these rules. However, we believe that such a stone deserves to be served properly.

So, we suggest you learn the rules for wearing diamond jewelry:

  1. In principle, you can wear discreet small diamonds at any time of the day, even during the day. Other rules apply exclusively to large diamonds.
  2. Wear large diamonds preferably in the evening, as they only look perfect in the evening light.
  3. Try not to display the beauty and elegance of diamonds in large stores and supermarkets - even the richest ladies do not do this.
  4. Wear a necklace with diamonds only under a dress with a neckline. But you must understand that such an outfit cannot be worn during the day.
  5. Large diamonds are not suitable for a business meeting during the day.
  6. Don't wear diamond jewelry, even the most discreet ones, to work. Remember, many directors do not feel comfortable if their employees wear sparkling stones. Accordingly, for office work, give preference to pearl jewelry.

And most importantly, wear diamond jewelry in a way that matches your outfit.

Stone cost

Black coral is a relatively expensive stone. Earrings and a bracelet will cost from 5,000 rubles, a ring can be found from 2,500 rubles, prices for pendants and necklaces range from 5,000 to 15,000 rubles.

The cost of a product is determined by the components included in it - the most expensive piece of jewelry was sold for $34,000. It was a diamond owl sitting on a branch of black coral.

Black coral is a rare find in the sea. A fragile, amazing stone, wearing which can change the owner for the better, attract attention to him, and help in the fight against disease.

Diamond deposits

Today, diamonds are mined in three types: the rock can be rich in intergrown crystals, there are single stones and polycrystals, which are intergrown grains of small diamonds.

In 2022, a double diamond was found in Yakutia, which was called “Matryoshka”. In the middle of the diamond, a second diamond was discovered, which was dangling in the mother nugget like in a nesting doll. Take a look at this unique find - the only one in the world - in our video.

Today, diamonds have been discovered on all continents except Antarctica; South Africa, Botswana, and Russia remain the leaders in diamond mining. In India, the country that started the diamond's rise in the world, reserves have been depleted and production has ceased.

98% of mined diamonds are yellow in color and have zero transparency; the stones are used in industry and are not used in jewelry. The discovery of a jewelry diamond is considered a great success for the company and a world sensation.
