What does a real ruby ​​look like?

Ruby is a colorful and transparent stone, almost as hard (9 on the Moss scale) as diamond (10).

A real ruby ​​can look different: the intensity of the red color, as well as the quality, depend on the deposit of the mineral.

The more iron and chromium oxides in a stone, the redder it is. So a ruby ​​can be colored in fiery crimson, red-brown and red-pink shades, or it can be yellow-red.

A highly valued mineral that shines with bluish or purple hues. This stone is called “pigeon blood” – one of the most expensive among rubies.

There are star rubies: after processing, a six-pointed star appears in the center of the stone. They are also among the most expensive.

Another type of jewelry is anionite. The mineral consists of green cyosite interspersed with dark pink or dark red ruby. Thanks to this, a beautiful design and a very high cost of the stone are born.

How to distinguish a real ruby ​​from an artificial one

Natural ruby ​​stone is obtained as a result of long natural processes. Experts grow the artificial mineral using various accelerated methods, and the chromium content in such samples is thousandths of a percent.

You can tell the difference between a man-made and a natural ruby ​​if you pay attention to the details.

As Emil Akhundov, commercial director at the Research Institute for the Development of Public Education, head of the “Opinion Leaders Factory” project, explains,

A real ruby ​​has a high density and is heavier than an artificial one.

In addition, natural ruby ​​has a high refractive index, brilliance and brightness. But since artificial stones can imitate these properties, it is necessary to test jewelry using special methods.

“If you want to verify the authenticity of a ruby, it is best to contact a professional gemologist who can conduct research using specialized equipment and techniques,” recommends Emil Akhundov.

But a quick inspection of the jewelry can be done at home.

For example, a magnifying glass with tenfold magnification will allow you to examine the stone in detail. A real ruby ​​has natural inclusions such as roughness, bubbles or cracks.

Microcracks in natural garnet will be zigzag-shaped, while in synthetic garnet they will be smooth and shiny.

You won’t be able to scratch a natural stone, but you can easily leave scratches on a glass fake.

An interesting experiment can be carried out with milk: a natural mineral immersed in liquid will color it pink. In a clear glass filled with water, the ruby ​​will emit a reddish glow. Synthetic or glass rubies are not capable of such an optical effect.

How to check the authenticity of a ruby ​​without special tools? If you only navigate visually, the following three parameters can help determine whether the stone is natural or not:

  1. Glossy shine. The reflections of the sun play on natural ruby; it shines through, but does not fade, unlike its synthetic counterpart.
  2. A real mineral glows and shimmers. Chrome, which is at least 2% in any ruby, glows violet-garnet in the sun.
  3. Cut: the edges of a natural stone are smooth and clear. They will blur artificially.

How are synthetic rubies made?

Man-made rubies are grown using a variety of technologies, including melting, hydrothermal processing and chemical deposition methods.

The main character in the production process of synthetic ruby ​​is corundum (alumina), consisting of aluminum oxide.

One of the ways to grow stone looks like this: alumina, silica and chromium compounds are placed in a crucible (container) and placed in an autoclave – a sealed apparatus.

In it, raw materials are subjected to high temperatures and pressure. After a change in temperature, minerals of various shapes and shades crystallize.

This process can take from several weeks to several months, depending on the desired crystal size. The resulting crystals are ground and polished.

Price as a criterion of authenticity

The value of a ruby ​​primarily depends on its weight. As with diamonds, it is measured in carats.

Taking into account the number of defects and the color of the stone, three price categories are distinguished:

  • pure gems. The defects are small (stripes and dots) and are visible only with the help of strong optics. Price 1 carat – $800-1500;
  • crystals with small inclusions of other stones, cracks in visible areas. Such stones sell for $500-800 per carat;
  • There are many defects, they are found all over the surface of the ruby, there are cloudy areas. The cost of 1 carat is $200-500.

Synthetic stones can be sold a thousand times cheaper. The same is true for glass “rubies”.

If you focus on the country of origin of the jewelry, then the most expensive rubies are those mined in Burma. Minerals from Mozambique will be slightly more affordable. Stones from India, Vietnam and Thailand will be cheaper.

Considering the high prices for jewelry with rubies, it is most profitable to purchase them in installments. For this there is a universal card “Halva” from Sovcombank.

There are special methods for establishing the authenticity of a stone: some of them can be used at home.

To insure yourself against buying a fake, choose jewelry from licensed jewelry stores. The price of the product is too low and should alert you.

For examination, you should contact gemologists – they are engaged in the classification and identification of precious stones.

A natural ruby ​​is a beautiful and expensive stone with a characteristic red color, characterized by incredible hardness, comparable only to a diamond. It has long been valued for its physical and aesthetic qualities and is considered a symbol of eternal love, courage and true beauty. In ancient times, lovers gave ruby ​​jewelry to each other before a long separation, in the hope that they would become a reliable amulet and a reminder of the giver. In the modern world, few people endow stones with magical properties, but a beautiful ring with a ruby ​​will be a welcome gift for any holiday and even for an engagement. Due to the fact that jewelry with natural stones costs a lot, rubies are often replaced with cheap analogues. There is nothing wrong with this if the seller directly says that the insert is not natural; in other cases, it is better to find out in advance how to identify a fake.

Features of ruby

  1. It is difficult to leave a chip or scratch on a natural ruby, because its hardness is 9 units on the Mohs scale. Even if the ring is not handled very carefully, the stone is unlikely to be damaged.
  2. Natural stone necessarily contains a number of impurities that are easy to see under a microscope or using a powerful magnifying glass. Pure and transparent natural rubies are also found, but they can hardly be seen on the shelves of regular stores. Such specimens are found at jewelry auctions and are very expensive.
  3. Natural rubies, even after cutting, rarely take an ideal shape with clear and even edges, but for a synthetic substitute this is quite natural.

Like many natural stones, ruby ​​has low thermal conductivity. If you hold a natural gem in your hands, it will remain cool for a long time.

Synthetic rubies

If you think that artificially grown rubies are a remake, you are mistaken. Verneuil technology, which is used to create synthetic stones, appeared at the very beginning of the twentieth century, so artificial red gems can be found even in antique jewelry. Since new crystals are constantly synthesized in laboratories, their market value is insignificant and there is no talk of any uniqueness here.

What are natural rubies substituted for?

Unscrupulous sellers often pass off the following as rubies:

  • garnets are fairly soft and dull silicate minerals of a dark red hue;
  • tourmalines are reddish-pink silicates, in their hardness located between garnets and rubies;
  • fragments of red glass – cheap and fragile, even in appearance they are far from real stone;
  • Composite rubies are crystals made from glass and ruby ​​chips.

The latter option is most often passed off as natural rubies and sold at the price of a natural mineral.

How to distinguish a fake

The most accurate way to check is the opinion of a gemologist or professional jeweler. But, if this is not the case in your city, several simple ways will help reduce the number of suspicions:

  1. Examine the stone using a powerful magnifying glass or microscope. If you see small white bubbles, cracks and other defects in the cavity, this is a fake. Inclusions of red color indicate naturalness.
  2. Bring the stone to a bright light source: the natural mineral will become darker.
  3. Shine an ultraviolet lamp on a ruby: the fake will take on an orange tint, while the natural stone will remain red.
  4. Pour water into a transparent glass and throw a stone into it. A real ruby ​​will glow red, but this will not happen with a fake.

In good jewelry stores, the origin and quality of stones are confirmed by relevant documents, so do not hesitate to ask for a certificate in the store.
