This is often the case with custom diamond rings: two diamonds have the same 4C grade, making it difficult to choose. Today, I will share this advanced version of the drill selection strategy, and after reading it, I will directly become half an industry expert.
If two diamonds have the same 4C grade, you can further choose from the clarity aspect, which is described below according to different clarity grades:
1. VS1 and above clarity grade
Diamonds above VS1 clarity are generally relatively clean to the naked eye, you can check the date of the certificate, the diameter of the diamond, if the certificate is within one year, choose the one with a larger diameter, the naked eye effect will be better.
2. VS2 and below clarity grade
There are 2 main types of VS2 and SI1 clarity diamonds: clean to the naked eye and not clean to the naked eye.
For diamonds in this clarity range, the flaws are in the cut-off line between whether they are visible to the naked eye, and if you don't pay attention to it, the type, size, color, and distribution location of the flaws will affect the effect of the naked eye, and also have an impact on the fire of the diamond.
(1) Clean to the naked eye
If the merchant is clear that the diamond is eye-clean, it can directly compare the date and diameter of the diamond certificate.
(2) The naked eye is not clean
If the eye-to-eye defects of the diamond are not obvious and more obvious, you can further communicate with the merchant to confirm the type, color, size, distribution and location of the defects, and choose the defects that are not obvious and the location is biased, such as some defects in the diamond crown, which can be directly covered with prongs when setting. Choose the one with a higher degree of eye cleanliness at the same price to avoid spending money on inferior diamonds that are not clean.
SI1 clarity diamonds are very popular in diamond buying experience, and they are worth buying because they are very cost-effective and eye-clean.
