GOLD

The range of gold products is constantly expanding, improving design, improving properties through the introduction of special additives in the alloy. This made it possible to obtain a variety of materials: white, green, blue, blue gold, etc.

History of gold, the value of jewelry

The first mention of the precious metal is connected with Egypt. It was here that gold was first used: at first for domestic purposes (those who sewed, made needles, others made chisels, knives, etc.), but very soon jewelry was made of it.

In order to increase the amount of metal, gold deposits were mined.

A large amount of it gradually accumulated on the territory of Egypt - more than 3,500 tons. But because of the wars, the stocks were lost. They moved first to Babylon, then to the Greeks. As time passed, the gold reserves were scattered all over the world. Now mining is carried out in different countries and in Russian lands, too.

The enmity between the states on this ground has become history.

The value of jewelry is determined by various factors, among which stands out:

• beauty;
• rare;
• durability.

But these criteria do not allow us to accurately determine the value of materials, because the meaning is constantly changing. It is possible to determine the approximate value of products. However, even this factor is not considered accurate. It varies depending on different conditions, for example, the price per kilogram of precious metal. Accordingly, its value is determined taking into account indirect factors. In addition, at different times, the peoples of different countries have put their own meaning into this metal.

Now it is mostly just a precious material that carries no sacred meaning for most people, but is still extremely valuable.

Precious metal (Au) - chemical, physical properties

According to the periodic table of Mendeleev, Au is a Group 1 element and is a yellow heavy metal. The formula of the chemical compound is always different, which depends on the conditions under which the material is formed. Properties:

• the melting point is 1064°С;
• density depends on the composition, in nature there are materials with different values of this value: 19.3-19.32 g/cm³;
• the atomic mass is 196.966569 grams/mol;
• high softness;
• plasticity;
• significant weight;
• metal is not magnetic;
• the material retains its attractiveness: it does not blacken, does not rust.

The precious metal is represented by different shapes and structures:

• nuggets - chunks of rock formed as gold from rock;
• gold-bearing ore - placer material, metal particles contained in other materials (e.g., quartz, iron), from which gold alloys are made.

Colored metal, shades

Jewelry made of precious metal can look different. Many people are used to seeing a lighter or darker yellow precious material. In fact, it has many more colors, all of which are real and contain a substantial portion of gold:

• pink;
• red;
• white;
• blue;
• green/lemon;
• blue.

Alloys are often confused with base metals. But this is real gold, although it is more difficult to distinguish by its appearance than yellow-colored material. Precious metal in other shades is often as expensive as the classic version. The price is high due to the content of precious stones (diamonds, topaz, etc.).

In addition, the gold content is often 58% or higher, which also affects the price.

A distinction should be made between gold and red gold. The difference in shades is noted: the items of the first group are characterized by a saturated red color, while red gold contains more additives. And the tone of the metal depends on what kinds of ligatures were used.

Types, types and grades of gold

Varieties of precious metal:

• monetary;
• banking;
• colloidal;
• double;
• born;
• Turkish;
• medical;
• sassal;
• food;
• refining;
• schlich;
• Dubai, etc.

There are many types of such material, which is due to the difference in composition. If the Siberian nugget contains only gold (provided that there are no ore impurities), the melted metal is often mixed with additives.

This determines the value of the items, as well as the grade (branding): 375, 583, 585, 750, etc.

Pyrite or "fool's gold" also occurs. This is an inexpensive material that only superficially resembles the precious metal. The best variant is gold bullion (the weight is determined by the troy ounce). Such items are considered the most expensive due to their composition.

The best gold is 999. This is the purest gold possible when compared to 583-size items like this.

Use of the noble metal

Today, the old royal gold (money in the form of coins) is no longer in use. Alloy is used, and it is often rhodium-plated, as a result of which the item can turn black. Ornaments with gilding also turn dark. The price of a blackened item is low.

However, the cheapest jewelry is the one with the least amount of gold.

Today, precious metal alloys are used to make a variety of products: gold watches, jewelry, electronics parts, and reflective coatings. Scrap gold is melted down, with items still being the most expensive (if the best ratio of ligatures was used in production). Many stores offer items online and can be chosen from photos.

Dream - to what do you dream of gold

It is believed that the precious metal in the dream - to a good change. The exact meaning depends on the details of the plot. The appearance of this symbol in a dream could mean that in real life, money will be attracted, there will be a good job, the probability of a successful marriage will increase. If you dreamed that the precious metal was lost, the dreamer interprets this situation as a sign of the loss of a unique chance in life. Looking at a catalog of gold jewelry is a sign of unfulfilled desires.

If you dream that your lover gives you a ring, it is a symbol of an impending wedding.
