What are the 4 c's of diamond quality?
A gemstone rating system consists of four main indicators:
This is the weight of a crystal and is equal to 0.2 grams. The carat got this name thanks to the seeds of the carob tree. The thing's that these seeds have a constant mass and since ancient times they have been used as a measure of scales, and in the Ancient East, jewellery merchants measured precious gems with these seeds.
There are three weight groups of diamonds:
- small (weight up to 0.29),
- medium (weight up to 0.99),
- large (1 carat and more).
There is a universal international system GIA, according to which the gradation of colours is estimated from letters from D to Z.
Colourless diamonds are categorized as D, E and F and are the most expensive. Only a highly qualified specialist will be able to distinguish brilliants of this highest category. G-H is the second category. They are also quite valuable, but they have a slight yellow tint, which is why their cost is lower. All other jewel from I to Z belong to the group of inexpensive colourless gems.
Gemstones of fancy colours are also highly valued and the darker they are, the higher the cost of such a crystal. There is a special rating system for them.
This is a parameter that shows the presence or absence of internal and surface defects of the stone, foreign inclusions in its structure. This is an important criterion that affects the quality of the gem and its cost. Even the smallest high-grade brilliant will cost more than a large, low-grade gem.
The quality of the cut of a crystal is much more important than the shape, and this parameter is the most important of the four. Here, the quality depends on the amount of light that the surface of the gem reflects. A flawlessly cut diamond can reflect up to 99% of the light.
There are many ways to cut diamonds and they are classified under the same GIA system, which divides them into several categories from Ideal to Poor.
All these 4 C's of diamonds qualities are always indicated on the jewellery label. And on the website Fjewellery, you can find them in the description for each model with gems.
