How do you get a lab-grown diamond appraised? 4 Key Steps to Ensure Authenticity and Value

Getting a lab-grown diamond appraised is a crucial process to ensure its authenticity and value.

This process involves several steps, including identification, grading, and certification.

4 Key Steps to Ensure Authenticity and Value

How do you get a lab-grown diamond appraised? 4 Key Steps to Ensure Authenticity and Value

1. Identification

The first step in appraising a lab-grown diamond is to confirm its origin.

This is crucial because the value of lab-grown diamonds can differ significantly from natural diamonds.

Institutions like the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) are known for their expertise in this area.

They use techniques such as spectroscopy, microscopy, and luminescence under shortwave ultraviolet light to determine the origin of a diamond.

Specialized instruments like the DiamondSure and DiamondView, developed by De Beers and marketed by GIA, are also used to aid in the identification process.

2. Grading

Once the diamond's origin is confirmed, it is graded based on various characteristics such as cut, clarity, color, and carat weight.

This grading process is similar to that of natural diamonds and is essential for determining the diamond's quality and value.

Independent laboratories like GIA and IGI are responsible for this grading process, which ensures that the diamond's attributes are accurately assessed.

3. Certification

After grading, the diamond is certified by the laboratory.

This certification includes a detailed report of the diamond's characteristics and a unique serial number, which might be laser-inscribed on the diamond.

For instance, some lab-grown diamonds from companies like Gemesis are inscribed with the words "Gemesis created" and a serial number prefix "LG" to indicate that they are laboratory-grown.

This certification is crucial for both valuation and disclosure to consumers.

4. Summary

In summary, getting a lab-grown diamond appraised involves a thorough process of identification, grading, and certification by reputable gemological institutions.

This process ensures that the diamond's origin is correctly identified, its quality is accurately assessed, and its value is fairly determined.
