Lab Diamond Certificate

Can lab-grown diamonds be certified? 

Yes, lab-grown diamonds can and should be certified.

All diamonds should go through a grading process that considers the 4Cs, no matter their origin. The 4Cs contribute to a diamond’s overall value and serve as the standard across all jewelers and grading agencies. Whether mined or sustainably grown, higher grade diamonds carry a higher value because purity is difficult to obtain.

What does a diamond certificate look like? 

Not all diamond certificates look alike. Various institutions or brands will have slightly different diamond certificates. The most important information to look for, however, is a diamond grading report based on the 4Cs.

I will let you how to read it or what all things to analyze in it,let’s start !

1. Date 

The date can tell us several different things. These details help us to judge the diamond. Is it brand new or graded which year? It helps in deciding what and which diamond to take. Its not bad to repurchase but only if the Diamond comes back in the best conditions.

2. IGI Report number 

Every report has a unique number and you can also view it from the IGI website. The Buyer can check the authentication of the report which is provided to them. 

3. Shape and cutting style 

As the people generally take the shape and cutting style as the same but these 2 things are different. The shapes are round, pear, square, oval, etc. There are different cutting style available like the Single cut, Brilliant cut, etc. 

4. Diamond measurement

5. Carat weight 

The Carat Weight explains how much is the weight of the Diamond. 

6. Color grade 

This identifies the color of your diamond by the GIA Color Scale (D-Z) and references its absence of color.

7. Diamond Clarity grade 

The clarity grade shows how many flaws contain in the diamonds. This is also shown by the chart called Diamond Plot, where the flaws are shown by the marking. 

8. Diamond cut grade 

The diamond cut grading considers the factors like table size, culet girdle thickness, etc.

9. Polish 

It means that the facets of the diamond are smoothly and perfectly polished. If any facet has been over polished or less polished or marked with flaws, they can alter light and even make your diamond look less shiny. Light can reflect off from these flaws and can create a dull impact.

10. Symmetry 

Symmetry refers to how closely the same kind of facets is proportionate. Like Star Facets should all be perfectly identical, they should all match up and look similar.

11. Fluorescence 

Fluorescence means the diamond has a Milky or Cloudy inclusion which makes the diamond looks dull in natural light. Even if that Diamond does not have any Flaws in it, that is a Diamond with white Color and an Excellent Cut. The diamond will glow when kept under UV light. 

12. Inscription 

The meaning of the inscription here is a Laser Inscription number, which means that the numbers will be written on the boundaries or the girdle of the diamond. With the help of diamond tools, you can see the numbers and identify the diamond correctly. Here is a pic show that how the inscription looks like on diamond:

13. Proportions 

The diagram shows the actual proportions of the diamond i.e. table size, width size, girdle thickness. Etc. This helps us to understand if the diamond is ideal for buying with the ideal proportion of diamonds.

14. Clarity characteristics 

The inclusions in the diamond are shown in the following diagram of the diamond. The inclusions are shown exactly at the same point in the diagram where it exists in diamonds. This helps to easily locate the inclusions in the diamond.
