Diamonds are a natural resource that is mined from the depths of the earth. The diamonds that come from nature have different colors that are clearly visible, and the color of the diamond is an important factor that affects the price of the diamond.
How color grading affects the value of a diamond
A diamond value is determined by a complex set of parameters. Four main parameters have a sharp impact on diamond value, and the diamond color is one of them.
Diamonds coming from the heart of the earth come in many colors and shapes. As the diamond is colorless (transparent), its value will also be higher than that of a diamond that has a yellowish color that is visible.
How colors are graded
The diamond color grading is done according to the ABC table, but the rating begins with the letter "D" symbolizing the highest level of diamond in the world, and its value is the highest.
The rating ends with the letter Z, which represents the diamond whose color and value is the lowest of all the diamonds in the world.
A D color diamond is a diamond that is crystal clear and has not a single drop of extra color.
A Z colored diamond is a yellow-colored diamond, and there may also be other additives such as brown, gray ...
The most common colors
The most common colors for jewelry are G - H diamonds, and these are because diamonds are very white and are priced much lower than the price of the same D diamond.
For years, diamonds have been a favorite item for women and men around the world, thanks to their special brilliance, history, and social status when you are a diamond jeweler.
The finished product of billions of years of raw material that has been cut from the depths of the earth around the world and polished to be the glittering and familiar diamond we all know from the movies and our small part own a personal jewelry collection studded with diamonds.
Rough diamonds are found in nature in a variety of shapes, some as long as a bottle and some square and hostile. The primary function of a professional diamond polisher is to refine the rough diamond and turn it into a polished diamond with minimal weight loss resulting from the polishing process. There are currently two advanced computer programs that work with lasers that scan the rough diamond and extract a sketch of several diamond cutting options according to certain shapes and by maximizing the weight of the diamond and losing as little weight as possible in the polishing process.
These are the most common diamond shapes
The round diamond has 57 strokes. 32 strokes at the top of the diamond and another 25 strokes at the bottom of the diamond. Another name for the round diamond is Brilliant Cut. Round shape is the most popular shape of all shapes. Round diamonds make up approximately 85% of all diamond shapes embedded in jewelry. At the beginning of the 20th century, discovered that if a diamond is polished according to a particular mathematical physics model, then the coefficient of breaking the light of the diamond will be maximized because the rays of light will optimally illuminate the diamond.
The Princess is the most famous square diamond. The Princes' cutting was invented by an Israeli diamantaire and became the best-selling shape after the round diamond. The diamond polishing method combines two different techniques. The first is the step cut, and the second is the Brilliant Cut. The combination of the techniques gives the diamond lots of cuts at many angles that make it a particularly sparkling diamond.
The emerald diamond is a polished diamond with a step cut technique and a rectangular shape. Cutting the diamond in this polishing makes the diamond transparent in its entirety. The sparkle level of the Emerald diamond is relatively low since most of the light entering the diamond goes out and does not "bump" into other walls that reflect and reflect the light in all parts of the diamond. Emeralds are only emeralds in relatively large sizes of 1 carat or more because they are relatively deep and with less weights, they seem too small.
The oval is an elongated shape in different proportions in the diamond parts. In fact, this is a combination of round diamonds and emerald diamonds, so that the oval shape "takes" from both worlds the benefits. The shape of the oval was invented in the 1960s by the American diamond corporation Lazar Kaplan. The Havel is especially suitable for women with a thin finger who do not want a diamond as wide as the round diamond for example, but they are interested in the brilliance and brilliance of the round cut. While the color and cleanliness of the diamond are a factor that has a significant impact on the price, but also the ratio between the width of the diamond and its length has a large impact on the price. The ideal model for the ratio between the width and length is 1.7. Which means that the length will be 1.7 times greater than the width of the diamond. Any scorching of the conventional proportions will significantly damage the brilliance of the diamond and significantly reduce its value.
Marquise is an old shape. As early as 1600, there are paintings by women wearing jewelry with marquise diamonds. This shape was invented in France and has become very popular over the years. The marquise has an elongated model whose ideal ratio is 1: 2. This means that the length of the diamond should be twice the width of the diamond for the diamond to be full of gloss.
A diamond cut in a drop is also known in Hebrew as a pear-cut diamond, which is spectacular and highly sought after due to its unique shape, perfect for embedding in a wide range of jewelry ranging from coins to pendants and earrings. You could say that this is a combination of marquise and oval, but it will not be 100% accurate. Pear has 58 cuts throughout. The exact ratio between the width of the diamond length is 1.6, meaning that the length will be 1.6 times the width of the diamond to maximize the breaking of the light and the brilliance of the diamond
The radiant is a square diamond but can also be rectangular. There are several options for polishing a radiant ranging from 53 to 70 cuts (depending on how deep the rough diamond was). The corners of the diamond are cut and not sharp. This is a trendy shape when it comes to colored diamonds because its unique shape conveys the light and the color of the diamond to the maximum and thus emphasizes the color of the colored diamond. The correct ratio for a radiant diamond in a square shape is 1.05 at 1.10, and if it is rectangular, then the optimal rate is 1.20 to 1.50.
As the name of the cut, it is a diamond whose shape is like a heart shape. The heart diamond has about 58 cuts. Its polishing technique is very similar to the polishing technique of the drop diamond. A diamond in the shape of a heart requires great skill because there are many parameters of symmetry that need to exist in parallel so that the diamond will return light at maximum. This shape is very popular because of its symbolism and because it can also be embedded in fashion jewelry such as pendants and earrings.
The cutting of the Cushion is also known in Hebrew as the cutting of the "pillow". This is a pretty rectangular or square polished diamond world known for more than 150 years. This is a refinement that has become very popular in recent years, especially in the American market, because this shape combines a lot of techniques that complement a very impressive final result. The difficulty, like the radiant, is a shape that upgrades colored diamonds due to the concentration of the color that is evenly divided and emphasizes the color. The difficulty is a very popular and popular shape of vintage engagement rings.
The clarity of a diamond is gauged using the differentiators below. With clarity, the types of diamond are gauged depending on the quantity and visibility of flaws.
The cleaning rating is divided into five main quality groups
The first group is symbolized in the FL - flawless IF - internally flawless and ranks the cleanest diamonds in the world.
This means that these diamonds do not have internal and external defects, and even if we examine them with a microscope that increases by 40 times, it will not be possible to detect the smallest particle.
The second group is marked by the very low-inclusion combinations V1S very slight inclusions, and it refers to very high-grade diamonds, in which the particles are very small and barely distinguishable through 10-fold magnifying glasses.
The third group is denoted by SI1 slight inclusions 1 and refers to the most requested level of cleanliness. This level is preferred by most customers because the quantity and size of the particles in the diamond are not large and do not appear unprofessional, and therefore their price is very attractive, although there is no visual difference between them and the diamonds in the two upper groups.
The fourth group is denoted by SI2 slight inclusions 2 - SI3 height inclusions 3 and refers to diamonds of class cleanliness
Medium - Low. This rank is very common in the US market because of its relatively low price. Even though this level is considered low, the diamond defects will not be easily visible, making diamonds of this grade attractive because of their low and glittering visual value.
The fifth group is symbolized in the combinations I1 included 1 - I3 Included 3 and refers to the lowest and lowest value grades. These diamonds will have a very large amount of defects that can easily be seen even with an unprofessional eye.
Size is the most visible factor that determines the value of all diamond types. The price of the diamond rises exponentially depending on its size.
By definition, 1 carat is 200 milligram. Since most diamonds sold in the market weigh less than 1 carat, the carat is usually subdivided into "points." There are 100 points in a single carat. So, a diamond weighing 3/4 carat would be a "75 point diamond".
1 carat = 200 milligrams = 100 points.
Weight groups for diamonds
The weight of diamonds is divided into weight groups with each group having its own price. For example, the "semi-carat" group starts with 0.50 points and 0.69 points. All the diamonds that are suitable for this group will be called half carats, although some will weigh more than half a carat.
The next group is the 3/4 group. This group contains all diamonds weighing between 0.70 points and 0.89 points.
For example, if we compare a diamond of the same quality of color and cleanliness between a 0.51-point (semi-carat) diamond that will cost about $ 2,500 and a diamond of 0.71 points (belonging to the 3/4 group) its price will jump to $ 4,000. As can be seen, price increases are not proportionate to weight gain because diamonds from the 3/4 group are rarer, and so are their value.
If we compare the same diamond from the 3/4 group to the same quality but from the 90-point group (that is the group above the 3/4), then the diamond that weighed 0.71 points will cost $ 4,000 compared to the same quality of 0.91 points which will cost $ 5,400.
A larger diamond costs more
It can be said that the larger the diamond, the rarer and its value is higher. This rule is permanent, and there are no outstanding diamonds.
The most common diamonds that customers choose to insert when they purchase pleasant engagement rings in sizes between 1/2 carat and 3/4 carat because these diamonds have a great presence and much more attractive price than the following weight groups.
