Criteria for evaluation
Estimating the value of a natural ruby depends on many factors. In this case, it is worth taking into account its weight, place of extraction, size, color. The cost is also affected by the presence of defects and cutting features. The price of real stones is determined not in rubles, but in American dollars.
Field
Rubies are found on all continents. The only exception is Antarctica. Stones are mined in large quantities in Asia. They are found in Vietnam, Thailand, and Ceylon.
African deposits are located in Madagascar and Tanzania. There are also rubies in Mozambique and Kenya. The largest stone, measuring 400 carats, was found in Burma. India is considered a promising option.
At the same time, the approximate cost of gems depends on the deposit. So, for 1 carat of a large ruby, which was mined in Burma, they can pay 2-90 thousand dollars. At the same time, crystals from Mozambique will cost much less. A stone weighing 4-5 carats can be purchased for $500.
Quality
Finding perfect rubies in nature is difficult. Usually they are distinguished by various defects - cracks or voids. High-quality gems are those that have no flaws. At the same time, there are inclusions that increase the cost. These include microcracks that form a six-pointed star.
Another quality parameter is cleanliness. Based on this feature, crystals are divided into the following groups:
- the first - includes small inclusions or thin cracks;
- the second – contains gems with minimal defects or condensations;
- the third includes opaque stones or gems with large opacities.
Important! Cost is affected by processing. Of particular value is a cut with correct proportions without chips, stripes or gouges.
The cost of the stone is affected by the type of processing. The number of crystals that do not require special thermal effects does not exceed 5%. Usually the stones are heat treated. This procedure is called refining.
To do this, the material is placed in chambers in which it is heated to 800-1900 degrees. Under the influence of temperature, the color of the ruby changes and extraneous shades are eliminated. The inclusions present in the stone melt. This leads to an increase in its purity.
When comparing stones that have undergone thermal treatment and ordinary ones, the cost of the latter, with other identical characteristics, is 2-3 times higher.
Upgrading often leads to cracks. Lead glass is used to eliminate defects. In appearance, the stone becomes perfect. However, jewelers classify such crystals as the cheapest. Their price is 1-20 dollars per carat.
Size
The cost of precious stones depends not on size, but on weight. Mass is considered the main characteristic. The weight of rubies is measured in carats. To understand the size, it is worth noting that 1 carat corresponds to 0.2 grams.
The price of a ruby is set not for 1 gram, but for 1 carat. But not everything is clear here. Small stones cost less than large crystals. Therefore, there is no direct connection between mass and price.
The cost of a ruby depends not only on the size, but also on the quality of the stone. However, the larger the dimensions, the less likely it is that the crystal will have an impeccable structure. Rubies weighing 3 carats are rare. At the same time, it is impossible to find gems weighing 5 carats without defects.
Color
How much a ruby will cost depends on the color. Real stone often has a red tint. At the same time, it changes from light to bright and saturated. Pink, purple or orange rubies are also found. These shades are associated with the presence of natural inclusions.
A pure ruby with a rich red hue is called pigeon's blood. In this case, according to the classification of colors, the following options are distinguished:
- bright red;
- medium red;
- light red.
Important! Descriptions of shades include saturation. Bright stones are much more expensive than light or dull ones.
What gems can be traded in?
The antique store carries out the purchase of jewelry with inserts of any stones. We can accept both modern jewelry and antique pieces.
That is, a product that belongs to the “precious” category is accepted by an antique store, regardless of its size and cut. Only a diamond that weighs at least 0.5 carats is accepted as a separate item.
The cost of a real ruby in Russia
The Russian Federation has adopted its own classification, which divides crystals into categories of defects and shades. The following groups are distinguished:
- Quality 1 – this includes pure gems that are distinguished by small defects in the form of stripes or dots. They are located in different places and do not merge. It is possible to identify such areas only with the help of special devices. 1 carat of ruby from this group costs $800-1500.
- 2 quality – crystals are distinguished by certain defects. These include small inclusions of other stones or cracks in visible areas. Their cost is 500-800 dollars per carat.
- 3rd quality – rubies are distinguished by large defects that cover the entire surface of the stones. The structure contains cloudy areas. Such gems cost $200-500 per carat.

How does an expert evaluate gemstones?

- Are there any foreign particles;

To protect the product from chips or other damage, you need to store it in proper condition. If you have a valuable heritage, then it is very important to take care of the quality of preservation of the stone.
Some purchases do not take into account the main criteria of the stone, and the gem is assessed only by the weight of the mineral, which makes it difficult to sell precious stones in Moscow. With such a valuation of the stone, the terms of its sale will not be profitable for the owner of the jewelry, because the minimum price is offered for the product. And all this happens due to the fact that many companies do not have experts - gemologists who can accurately determine the real cost of a stone. Perhaps this is beneficial for someone, but not for us, because our antique store “Arbat, 40” operates in accordance with the law, and a client who comes to us can count on high-quality and safe services.
