Four factors on which to evaluate a diamond. (cut, color, clarity, carat weight)
Fire: the flashes of color you see in polished diamond
Colored flashes of diamonds
Facet: a flat, polished surface on a finished gem

Shaving in diamonds:
Round brilliant lath is a common diamond lath.

,
Low-weight diamonds often cut single cuts.
Each lathe has a shape and a style
The quality of the diamond polishing and polishing is impressive.
The weight in diamonds is based on the weight of the carat
Which is briefly ct.
Diamond Cleanliness:
Two factors of surface impurity and internal impurity affect diamond purity.
The standard magnification for purity check is a 10x diamond.
Diamond Purity Examination is the specialty of those who have passed the evaluation and grading of diamonds and have experience in diamond evaluation.
Five Factors Influencing Diamond Cleanliness:
Size: The greater the size of the impurity, the greater the impact
number: The number of impurities
position: The location of the impurities
Nature: The nature of impurity
relief: The level of impurity
Diamond purity grades
The color table in diamonds was introduced by the GIA in the 1950s with the efforts of Richard T Liddicoat.
The diamonds range from colorless to light yellow and light brown
Normal color range:
Color in diamond:
Blemishes other than FL and IF are not considered to be effective in other categories.
At lower weights, the customer's plot is included in the identification. Plot is made for full report identifiers, which are issued for diamonds above 1ct.
Plot
Colorless diamonds are less scarce than diamonds that tend to be yellow, so they are more expensive.
Colored diamonds:
In some fancy color diamonds the color is not uniform, some fancy color samples are pale. And sometimes the main color has a gray or brown background.
In fancy color diamonds of a natural color with a decent color concentration are very rare and expensive.
People's recognition of colored diamonds began in the 1980s when the Australian Argyle mine offered brown diamonds.
With the efforts of the mine, people have become more aware of colored diamonds. The mine still offers brown diamonds, though the mine is more known for its pink diamonds.
Diamond Pricing:
Determining the price of a diamond is based on its four factors of purity, color, weight and shaving. The price of a diamond is determined by monthly and sometimes weekly listings.
Diamonds weighing more than 0.50CT should be well-known Having a birth certificate from a gem lab facilitates the pricing process of a diamond and, on the other hand, creates greater customer confidence.
Small diamonds and diamonds, especially jewelry based mounts, are not commonly identified. In this regard, the seller should indicate the number and weight of small diamonds in the purchase paper, as well as the selling price of these diamonds.
In cases where the number of these small diamonds is high, the seller may indicate the total weight of these diamonds must be precise and the overall price of the diamond must be specified.
The price of each ct of these diamonds will be determined by the weight and price mentioned Article by Nima Monzavi (Gemologist)
