It nearly takes millions of years for coal to convert into a diamond. The fact that its origin is charcoal basically with some impurities and moisture in it, the diamond is itself the purest form of carbon.
Mostly, coal needs the right amount of pressure, stress, and tenure to completely transform into a pure gem. Despite the fact that diamonds are rare, it is also necessary to buy them with great caution.
The reason is that some laboratories are also producing synthetic diamonds which are factually artificial. And if anyone is considering to buy authentic ones they need to consider a few points in their minds.
Various Diamond Color
The diamond comes in so many colors that one cannot deny its beauty. Usually, this gem is valued on the D-Z scale, the colorless ones come under D-zone. And this way the shade pattern goes from transparent to yellow-brownish Z-zone.
While color is a solely individual preference, but the colorless diamonds have higher prices than the colored ones. But at first place, expert ideas are always needed to analyze these precious stones worth.
Evaluation of Diamond Clarity
Due to high pressure and temperature, some stones lost their clarity and only experts can recognize it. They use a high powered x10 magnifying glass to ensure the clearness of a diamond. It is true that the flaws affect the transparency of a diamond to too much extent.
Though it can be the least concern for a common man because the usual flaws cannot be seen with naked eyes. The flaw or crack can be either internal or external, so the marks can be judged according to the grade of;
- FL (Flawless)
- IF (internal flaw)
- VVS1 and VVS2 (Very slightly internally included)
- SI1, SI2, SI3 (slightly included flaw)
- I1, I2, I3 (flaw can be seen without magnifying glass aid)
Determining Diamond Carat Weight
All the gemstones are measured in weight with the help of Carat (Ct). Consequently, the carat weight also increases with size and diameter, and the prices of diamond levels up as well.
According to a rough estimation, the cost becomes double with the increment of a carat and dimension. Though 200 milligrams lie in 1 carat, the price correlates to other 4Cs as well, especially the cut and shape of the gem.
Reflecting Diamond Cuts
A diamond is the hardest substance on earth, it is nearly 58x harder than anything. So it can only be cast into shape by a diamond itself. The round shape is the most expensive one, whereas, the oval is the cheapest.
Honestly, the raw, newly discovered diamond has no shape or cut. Then it is being molded into different shapes. Though the cut is the matter of brilliance, fire and sparkling, the cut only represents a diamond’s reflecting power.
The diamond can be the wealthiest jewel one can possess. Altogether the 4Cs are the most renowned method for determining diamond’s value, The GIA certified loose diamonds possess all the above-mentioned qualities and characteristics that one can look for.
