The question we should ask ourselves is – does the certificate that comes with the diamond describe the stone accurately?
Sadly enough, the answer to this question is a definite No.
In this post we will discuss the different laboratories in the diamonds world and reveal all the secrets and warning concerning natural diamonds that are graded by different gemological institutes.
I am sure that many traders in this industry will not like this post which will expose and show the difference between the diamond laboratories.
Let’s start with the biggest problem the consumer is facing when purchasing a certified diamond.
Original diamonds are a natural resource that comes from the ground.
It’s not a patent which makes it harder in defending the consumer.
As a natural resource, anyone can open a diamond laboratory and grade the diamonds based on his eyes only.
The problem is that there’s a price list for diamonds based on their weight, color & clarity.
Therefore, for example, if a strict lab will grade a diamond as F VS1 for which the price list in 1 carat is around $10k, another lab which we nickname as “fun lab” and much less strict will grade the same diamond as D IF or VVS and by that the “value” of the diamond will go up in the price list to $16k-$18k per carat.
