Ruby is a gem with unique properties. It is especially beautiful, resistant to mechanical damage, attracts attention with its modulations, therefore it is highly appreciated among other stones. More expensive than a ruby can be realized only the rarest diamonds - pink, blue and green. The most expensive stone is determined not by the analysis of characteristics, but by the place of extraction. Burma is the birthplace of the world's best rubies.
The gem is an unusual mineral. It combines a number of minerals. Pure corundum is a transparent, scarlet color of ruby imparts an admixture of iron oxide or chromium. Rubies from Burma are stained with chrome, which provides increased fluorescence to the stone.

A ruby with an intense red hue is more appreciated than less bright stones.
Color is the most important characteristic of ruby quality. Color includes hue, hue and saturation.
The basic shade of ruby should be red. However, there are stones with orange and purple hues. There are secondary shades that either emphasize the primary color, or spoil. However, the choice of shade depends on the tastes of a particular person.
This parameter characterizes how ruby is light or dark. The most valuable are average tones. Too dark or light tones worsen the visual effect of the stone.
It determines the intensity of the shade. The brighter and more saturated the color, the more appreciated the ruby.
The less ruby is interspersed and the less noticeable they are, the better the quality. It is best to choose rubies with defects that are invisible to the eye, but are visible only with an increase.
There are stones called "star rubies", whose defects and impregnations adorn and give the stone a special uniqueness.
Such rubies are polished like cabochons, which allows them to reflect the incident light in the form of a star with six rays. This is due to the optical effect, which gives impregnations similar to a spider web.
Cutting is a pretty significant characteristic of ruby. Firstly, it is designed to improve its shape and appearance. Secondly, the proportions and symmetry of the cut determine the ability of the stone to reflect and refract light, creating luster and sparkling. Thirdly, the cut must ensure the durability of the stone, protecting some of its sharp parts from possible impact or damage.
You can buy ruby in all existing types of cuts. But the most popular and expensive is round cut. Such a ruby should not be too deep.
The depth of the round stone should be 60% -80% of its width (diameter of the belt). Low purity stones are often cut like cabochons. They are evaluated based on symmetry, transparency and brilliance.
It is very difficult to evaluate the cut, as there are different opinions and patterns of how an ideal stone should look and what criteria it should have. Therefore, when choosing a suitable ruby, you need to be guided, first of all, by proportions and radiance.
Processing and improvement.
Today there are many rubies on the shelves of jewelry stores that have been heat treated to enhance color. Typically, the result of such processing is stored for a very long time. Sometimes stones are even specially painted to increase their value.
Some rubies are treated with a special material to mask impregnations and make it more transparent. However, the effect of such processing is not long-term.
In any case, before buying a ruby, you need to ask the seller about the processing methods to which he was subjected. It is even better to ask for a certificate confirming its quality. In general, a natural ruby with natural beauty will cost significantly more than processed stones.
Tips for choosing.
When buying a ruby, it is better to choose a stone that comes with a certificate proving its authenticity and origin. This is especially true if it is expensive and you need to be sure of the authenticity of the high quality of this stone.
Before buying, you must definitely be interested in possible processing in order to improve the properties of ruby. Since then this can affect its inspection, cleaning and maintenance. In addition, you need to find out whether the purchased ruby is artificial or natural.
Ruby is one of the most popular gemstones among jewelry lovers, but its popularity also means that there are many fakes that some sellers try to pass off as real rubies. Let's see what fake rubies are made of and how you can identify these fakes.
A fake ruby is made from an artificial material such as glass or a non-ruby mineral.
It is important to distinguish between fake ruby and synthetic.
While fakes have different chemical and physical properties compared to real stone, synthetics have the same chemical composition, and is, technically, a real ruby.
Stones used as imitations.
There are some gems that look like a ruby and can be used as analogues. For example, red garnet is very similar to ruby and can replace it. To simulate ruby, red glass is also sometimes used.
Unlike analogues, synthetic ruby has the same structure as natural stone. But he was created in the laboratory. It has higher purity and is more affordable.
Stones commonly used as ruby imitations are other natural red minerals, as well as colored glass. Here are the most commonly used ruby imitations:
Tourmaline: This is a silicate mineral, whose hardness is rated at 7.0-7.5 on the Mohs scale of hardness. Its pink-red variety is often used as a ruby imitation, but tourmaline is much milder.
Garnet: This is another silicate mineral. Pomegranate has many different colors, but its red variety is what is sold as a ruby imitation.
Like tourmaline, garnet is softer (garnet hardness rating on the Mohs scale is 6.5-7.5).
Glass: Many fake rubies sold in the market are made of red stained glass. These simulations are very cheap, but they are also not very durable.
Composite Ruby: It is made of real ruby, fused with glass. The purpose of combining these materials is to increase the size of the stone while reducing its selling price compared to a real ruby.
The problem with composite rubies is that they can easily break and be damaged by chemicals used in everyday life and when repairing jewelry.
How to distinguish fake and genuine ruby?
Here are the most common differences between real and fake ruby that can help you identify a fake:
Hardness: Substitutes such as tourmaline, pomegranate or glass are softer than a real ruby. This means that fake rubies made from these materials will be more easily scratched.
Weight: Most fake rubies are less dense than real ones. This is easy to establish if you weigh a fake ruby - its weight compared to a real ruby of this size will be less.
Price: How much ruby is worth is an indication of how likely it is to be real. Ruby is a rather expensive gem, so if someone sells it at a suspiciously low “bargain” price, it is likely that it could be a fake.
However, sometimes a ruby can be cheap just because it was created artificially, but in this case, its price should be much lower than the price of a real ruby like that.
How to identify a laboratory-created gem?
Many rubies that are sold today are not natural resources, but actually created in the laboratory. But is there a way to find out if a natural ruby or is it grown by a laboratory? Let's see how you can find out.
Synthetic ruby (also known as created, cultured or grown by the laboratory) is created through an artificial process that usually involves the use of heat and pressure.
From a chemical point of view, an artificial ruby is no different from a natural ruby and is considered a real ruby.
Testing includes analysis of the physical structure and chemical composition.
Although the synthetic and natural ruby are virtually identical, there are some very subtle differences that can be detected by the corresponding equipment.
A gemologist can tell if ruby is a synthetic product by looking at its structure under a microscope.
The ruby has the so-called "growth lines" - structural patterns that arise during its formation. Growth lines in synthetics are characteristically curved, indicating artificial origin.
Laboratory-created rubies can also have microscopic gas bubbles inside that form during the manufacturing process.
The creation process leaves certain chemical traces in the stone that are not present in natural minerals. For example, even a small amount of lead may indicate an artificial origin.
Although laboratory testing is the most accurate way to find out the origin of a ruby, it is not always reliable. The processes of creating the gem are constantly improving, and the rubies created by the laboratory become almost completely identical to their natural counterparts.
Signs that ruby may be grown by the laboratory.
If you do not have the opportunity to send your ruby to a laboratory for testing, there are more practical ways to determine if it can be a synthetic product.
Look at the following symptoms (but keep in mind that none of them is definitive evidence of origin):
Artificial ruby is created in a controlled process that minimizes the presence of internal defects. As a result, synthetic stones have a higher purity than most natural stones.
It cannot be said that an impeccable ruby is necessarily artificial, but if such a stone is real, it will be very expensive.
If a high-purity ruby is significantly cheaper than a comparable natural one, then you are probably dealing with a synthetic product.
Large natural ruby is rare and very expensive. For example, it is easier to produce synthetic ruby, which is 1.5 carats, than to find a similar one in nature.
However, there are also limitations on how large a ruby can be created. (On the other hand, production methods continue to improve.)
However, if ruby is quite large and affordable, it could be a synthetic product.
If ruby is relatively cheap despite having a few flaws, is quite large and has a rich red color, then this is a sign that it can be created in the laboratory.
However, if the price is too low, it should be remembered that this may be a fake.
It is a good idea to compare the prices of a natural ruby with a stone of a similar color, clean and weight, synthetics will be 10-15% cheaper, while fakes can cost 90-95% less.
Remember: the surest way to establish whether a ruby is a synthetic product is to either ask for a certificate confirming its origin (if the gemstone has such a document), or send it to the laboratory for verification.
