Round diamonds (KR-57) are considered the most expensive and most valuable form of diamond cut. The price for diamonds of all other cut shapes is calculated differently – compared to the round shape, fancy diamonds are 15-20% cheaper.
Details
For an accurate impression of the size of the diamond, focus on the size standards for the round cut KR-57: 0.25 carats – 4.2 mm, 0.35 carats – 4.5 mm, 0.50 carats – 5.0 mm, 0.75 carats – 6.0 mm, 0.90 carats – 6.3 mm., 1.00 carat – 6.5 mm.

Absolutely colorless
Colorless
Off white
Diamond clarity
For most jewelry, it is sufficient to select a stone clarity of no higher than VS1(4), VS2(5) or even SI1(6). Such a diamond will be impossible to distinguish from ideal IF-VVS without special skills and instruments.

Supreme purity
Better cleanliness
Average purity
Certificate
If you are buying a large diamond, we recommend choosing a stone with a certificate from the GIA or the Smolensk Gemological Center SGC. For diamonds up to 1 carat, a certificate for the product is quite suitable.
Details
Diamond fluorescence is an effect that almost all diamonds have. The effect is noticeable when the stone is placed under an ultraviolet lamp and appears as a blue glow inside the diamond. Diamonds without fluorescence are quite rare in nature, which is why they are more expensive.
Details
“Very Good” (B) is the basic parameter for cutting a diamond. Excellent cut – can increase the value of a diamond by 7-20%. Group B cut – “Satisfactory”, on the contrary, reduces the cost of a large diamond by 10-20%.
Details
Diamonds have the same characteristics, but they can cost differently, depending on the nature of the inclusions and their location. For example, diamonds with inclusions located at the back or on the edges look a little better and will cost a little more. This parameter is important if you are selecting the ideal characteristics of a diamond.

There are four main characteristics that determine the quality and value of a diamond. They are called 4 – C (carat, cut, color, clarity). After you learn everything about 4-C, it will be easier for you buy a diamondthe one you want.
The price of a diamond is made up of 4 – C
Carat – weight
The weight of diamonds is measured in carats. The word carat comes from the name of the grains of a tree, with the help of which valuable things were weighed in ancient times. In other words, these grains were used instead of weights, each grain weighing 0.20 grams. Today, to accurately determine the carat weight of a diamond, the carat itself is divided into 100 units, i.e. weighing to one hundredth of a carat. Many people mistakenly believe that carat is a measure of size and not weight. The larger the diamond, the more it weighs and, accordingly, the more expensive it is. When mining diamonds, large stones are more rare than small ones. Therefore, the higher the carat weight, the higher the price and this relationship is geometric.
Diameter depending on weight
It is also important to understand that the proportions of a diamond have some effect on its apparent size and a 2 carat diamond will not have twice the diameter of a 1 carat diamond because. The depth of the stone also increases.
Due to the different cut shapes of a diamond, a diamond that appears larger to the naked eye or from a certain angle may actually weigh less than expected. Although weight and size are related to each other, cut shape and proportions will affect the apparent size to a certain extent.

Cut – cut
The quality of a diamond cut includes the diamond’s proportions, symmetry, and polish. The quality of a diamond’s cut has a big impact on its appearance; the higher the quality of a diamond’s cut, the more it will shine and sparkle. Based on mathematical formulas, a perfectly cut diamond will reflect light from one facet to another and scatter light rays in all directions, resulting in magnificent brilliance and sparkle.
Although nature determines the color and clarity of a diamond, the quality of the cut and shape of a diamond depends solely on the qualifications, knowledge and experience of the diamond appraiser and cutter, who control the entire process to achieve the best results (brightness and sparkle).
Brightness is the strength and amount of light that comes out from the top of the diamond into the eye of the observer. High luminosity means that a large amount of light is emitted from the top of the diamond and this makes the diamond very bright and beautiful.
Sparkle is sparkles of all colors of the rainbow. These colors are created by the decay of light rays on the diamond’s crown.
Proportions.
The ratio of the width and depth of the diamond creates the greatest effect of refraction of the light beam, as light passes into the diamond, is refracted in it, and exits the diamond through the crown.
The following ratio options are available:
A perfect diamond – when the cut is done in the correct ratio, light enters the diamond, is reflected in its facets and comes out in a large number of rays through the crown. The diamond sparkles and plays.
Deep diamond – when, due to excess depth, light rays go through the sides of the diamond, and not through the top, the diamond does not shine and looks dull.
Shallow Diamond – When a diamond lacks depth, light passes through the entire diamond and comes out from the bottom, the stone loses its sparkle and fire.
Dimensions and properties.
A round diamond consists of the following main parts:
The crown is the top part of the diamond.
Band – A band around the widest part of the diamond that separates the top of the diamond (crown) from the bottom (chaplet).
The halo is the lower part of the diamond from the girdle to the spire.
Diameter – the width of a diamond is measured by the diameter of the band. Other characteristics are measured as a percentage relative to the diameter, and the diameter is taken as 100%.
Depth – The height of the diamond is measured from the Spire to the Landing.
The platform is the largest facet of the diamond, which is located above the crown.
The spire is the facet at the tip of a diamond that is usually not visible to the naked eye.
Polishing and symmetry.
Polishing and symmetry are very important factors in the diamond cutting process.
With poor symmetry, the light that enters the diamond will be unevenly distributed and will not exit the diamond correctly, resulting in a loss of brightness. If the surfaces of the edges are poorly polished, they lose their ability to sparkle.
Polishing.
Polishing refers to the smoothness of a diamond’s facets.
Defects in polishing such as marking lines and rough surfaces.
Symmetry.
Refers to the alignment of a diamond relative to its axis. The facets should be straight and merge in a perfect way with each other to form the tip of the diamond (spire).
The finished diamond in gemological laboratories is studied, measured and assessed for the quality of the cut based on all 3 indicators: proportions, symmetry and polishing of the diamond.
There is the following scale for assessing the quality of cut.
The ideal cut is a diamond cut at the highest level, such a diamond reflects the light rays through the crown as much as possible, resulting in magnificent brilliance and play of light.
Very Good Cut – This diamond reflects most of the light, brilliance and brilliance with only slight variations from a perfect cut.
A good cut means a diamond reflects a lot of the light that penetrates it. Suitable for people who are willing to compromise between quality and price.
Normal cut – The diamond reflects half the light through the crown, a compromise between quality of cut and maintaining the weight of the diamond.
Poor cut – made for the sole purpose of maintaining the maximum weight of the diamond. With this quality of diamond cut, most of the light is reflected through the sides and bottom of the diamond, resulting in poor brilliance and lack of play of light.
When purchasing diamonds, it is important to understand that the quality of the cut plays an important role in calculating the value of the diamond. For example, Diamonds that are Perfectly cut in all 3 dimensions are rare and difficult to produce. Thus, they are much more expensive (with the same characteristics of weight, clarity and color) than well-cut diamonds.
Color – color
White diamonds.
The color of a diamond has a big impact on its value. The color of white diamonds is classified alphabetically from D to Z, if color D is colorless and the most expensive, then gradually moving to color Z (light yellow) the price of the diamond drops significantly. The differences in color between adjacent letters of the alphabet are very small, for example: the difference between the colors D, E and F is difficult to distinguish even with the eyes of a professional.
diamond color rating scale from D to Z
White diamond colors can be divided into groups:
Gh
Very close to colorless diamonds, a slight difference can only be detected in close comparison with colorless diamonds.
IJ
Next to colorless diamonds, a slight yellow tint is found in the diamond.
KLM
Very faint yellow tint
NZ
Diamonds range from yellow to yellow in color.

Diamonds in fancy colors.
Fancy colors include colored diamonds such as blue, green, yellow, pink, purple, a combination of these colors and much more. These diamonds are very rare and very highly prized.
They are graded on a different color scale than white diamonds (D to Z). A fancy yellow diamond cannot be found by the grade of white diamonds.
The intensity of the fancy colors is very important in determining the price of a diamond; the more intense the color, the more valuable the diamond.
Fluorescence.
A fluorescent diamond can change its color, from colorless to fancy. When we talk about a fluorescent diamond, we are talking about its ability to fluoresce into a specific color (usually blue) when exposed to ultraviolet (UV) light.
Although fluorescence is a characteristic that can be measured, it is rarely an issue when selecting a diamond. The fluorescence of a diamond is assessed by the intensity of its glow: none, weak, medium, strong and very strong.
Clarity – purity.
This refers to how clear and clear a diamond is – diamonds that are absolutely clear are very rare and therefore the most expensive. Most diamonds contain natural imperfections in the form of inclusions such as traces of minerals, air bubbles, microcracks, etc., which are found within the diamond. They may appear as tiny crystals, black dots, clouds, or feathers. These inclusions reduce the diamond’s value and affect its clarity and beauty.
When determining the clarity of a diamond, it is important to take some facts into account, such as size, location, color, angle, thickness, and the number of inclusions.
All gemological research laboratories (GIA, EGL, AGS, IGI, etc.) have special rules on how to correctly assess the clarity of a diamond.
Diamonds are divided into the following groups according to purity:
IF – Flawless: no internal defects or inclusions. Very rare diamonds and very expensive.
VVS1, VVS2 – Very, very small inclusions: very difficult to see inclusions at 10x magnification. Rare and expensive.
VS1, VS2 – very small inclusions: inclusions are not visible to the naked eye. High quality.
SI1, SI2, SI3 – Slightly visible inclusions: inclusions that are difficult to see with the naked eye. Good quality.
I1, I2, I3 – Visible inclusions: inclusions and defects visible to the naked eye.
