One of the most important factors that play a key role in the quality of diamonds and diamond jewelry is their certification. You must know that internationally recognized and independent labs like the GIA test and evaluate diamonds to ascertain their quality and provide a certificate that verifies their grading. Also, keep in mind that the grading of some labs are not consistent because they are not strict in their evaluation process. GIA and AGS are two of the most consistent labs. In this article, we will discuss in detail GIA certification, and shared below are details about this.
What Is Diamond Certification?
When you buy diamonds and diamond jewelry certified by GIA, you receive a document that describes all the characteristics of the stone. You can also use this document to evaluate the quality of the stone before purchasing it. Some of the elements that are used for grading a diamond are its color, clarity, cut quality, carat weight, length, and width. This is done by trained professionals called gemmologist, and they use tools like a microscope and loupe for this purpose.
You must also keep in mind that there will be variations in the certification provided by different grading entities. For instance, GIA certification will be different from that of AGS certification. Sometimes, this difference will be significant, and hence it is important to know which labs are reliable and trustworthy. Moreover, the value and price of diamonds cannot be compared across varying certifications because the certificates provided by the third-party labs are not created equal.
What Should You Look In Diamond Certification?
Consistency
The most important factor that you must consider when choosing a diamond grading entity is its consistency. For example, the color, clarity, and cut grades are only as good as the reputation of the certifying lab.
Diamond Grading Is Subjective
Remember that the grading of diamonds is subjective, and this is similar to the value of diamonds. Also, there is no central organization for creating unified standards for the factors used for determining the quality of these precious stones. Above all, keep in mind that it is not wise to buy a costly diamond with a weak certificate.
Consider The Price
Do a GIA certificate check before buying a diamond and use this to evaluate the price of the stone. Remember that the price must justify the cut, quality, and beauty of the stone. For this, you could make use of a diamond expert review or the opinion of a gemmologist.
On a final note, when buying diamonds online, compare between stones that are certified by the same grading entity.
