Diamond Classification Standards
Diamonds in general, and natural diamonds in particular, are considered the king of gemstones. They possess outstanding physical properties and are regarded as the most perfect in the gemstone hierarchy. So, what is this assessment based on, and what role do diamond grading standards play in this process? Let’s explore the article below to understand it better.
Why are diamonds so favored by the aristocracy? Since ancient times, diamonds have been considered one of the jewelry items of the wealthy. They were often chosen as engagement rings for royal classes.
The value of diamonds
Outstanding characteristics
Nowadays, natural diamonds are not only chosen as engagement items, but they are also highly valued by people in terms of feng shui. Diamonds are one of the gemstones with the most complete physical properties. They are the material with the best hardness among all gemstones.
Natural diamonds are very difficult to scratch, and this is considered a very clear diamond grading standard compared to other gemstones. Therefore, they are widely used in jewelry making, with their diverse colors combined with the craftsmanship of artisans. The beauty of this rare gemstone, when displayed, easily leaves us astonished and captivated.
The meaning of diamonds
Diamonds symbolize the eternal and sincere love of couples. They express the faithfulness that two people have for each other. In addition, they also enhance one’s luxurious beauty.
Diamonds also carry great significance in feng shui. They are considered a talisman that removes impurities and brings luck and prosperity to the owner. To choose a quality diamond, people rely on standards to classify diamonds—so how is this done?
What factors are diamond grading standards based on?
Diamonds are considered the queen of gemstones. Their formation conditions are already harsh, and diamond grading standards are even more carefully regulated. Diamonds are evaluated and classified based on 4 factors, collectively called the 4Cs, including:
Carat
Used to determine the weight of a diamond, 1 carat = 200 milligrams. Weight and price are directly proportional to each other, following a certain exponential progression. However, its value also depends greatly on 3 other factors.
Color
Color is one of the most important standards for determining the value of a diamond. Color reflects the clarity of the gemstone. Its quality is graded in descending order according to the alphabet from D to Z, in which D is the clearest and Z is the most opaque yellow.
Clarity
It helps us determine scratches, color, and the location of fractures. However, this is not the factor that greatly affects the external aesthetics of the diamond.
Cut
This is the factor that determines the aesthetics and brilliance of the diamond. Well-proportioned cuts are always an important factor that helps a diamond become more radiant.
In addition to the 4 diamond grading standards above, sometimes people also rely on the 5Cs or 6Cs standards, which are price and certification, but these are not as important as the 4Cs.
What is the selling price of diamonds? Where to buy from a reputable source?
The selling price of a diamond increases as the weight of that diamond increases. You can clearly see this when referring to the selling price of a diamond:
A 5 mm diamond, weighing 0.45 carat, D color, VVS1 clarity, is sold for 54 million VND
Also a 5 mm diamond, weighing 0.5 carat, D color, VVS1 clarity, is sold for 59 million VND.
