Diamond Appraisal 101

Diamond Appraisal

Looking to Know Your Diamond's Value?

There are many of us who own diamonds that have either been given to us as a gift or inherited from a loved one. While we enjoy these diamonds, we also tend to wonder “how much is my diamond worth?” Diamond value is an interesting question and the answer is not found in the price tag. While there are a couple of ways to get a diamond evaluated it is most important that whoever is examining your diamond is fully qualified and objective. 

What is a Diamond Appraisal?

When it comes to diamond’s value, some terms are often misused and their meaning is not always clear. Most people think that a diamond appraisal reveals the diamond’s absolute value. But actually, appraisals are carried out for a specific purpose, like insurance or tax. There are 27 types of appraisals to suit different purposes! This means that the value stated in the appraisal will only be valid in that specific context and it doesn’t reflect the unalterable value of the stone.

Diamond Appraisal vs. Diamond Grading

While diamond appraisal is the process of assigning monetary value to a diamond for a specific purpose (insurance, tax, divorce, etc), diamond grading is the thorough evaluation of a diamond and its attributes: carat, cut, color and clarity. Diamond gradings are carried out in renowned gemological laboratories like GIA and IGI by certified professionals. The market assigns value to diamonds according to their grading, so if you know your stone’s 4 C’s, you can get an estimated market value, like the ones provided for free by Worthy. Ultimately, a diamond grading report is the most transparent, accurate and objective tool you need to determine how the market values your diamond in a specific moment in time.

Where to Get a Diamond Appraisal?

If you’re looking to get your diamond appraisal for a specific purpose like insurance or tax, the most obvious place to begin is at your local jeweler. Local jewelers should have the tools and the know-how to carry out a diamond appraisal accurately. But if you’re looking to sell your diamond, you might consider getting a more objective grading from one of the following institutes worldwide:

GIA: Gemological Institute of America
EGL: European Gemological Laboratory
IGI: International Gemological Institute 
AGS: American Gem Society 

When you decide to sell a diamond with Worthy, we provide GIA and IGI grading reports, at no cost to you. A proper diamond grading is vital to us and we only trust the very best in the business to carry them out. 

The Diamond Grading Process 

  1. Cleaning. This is the first step in a diamond evaluation because In order to see your diamond clearly and assess it accurately the evaluator must polish away any superficial flaws.  
  2. General Condition Overview. At this stage, the certified professional simply looks at your diamond without any tools to see if there are any scratches and to verify that it is in fact a real diamond.
  3. Measurement and the 4 C’s. This refers to the 4 factors that go into evaluating a diamond. They break down to carat, cut, color, and clarity. 
  4. Description. At the end of the diamond grading process, the evaluator writes a detailed summary based on their findings. Some descriptions include an estimated market value, however here at Worthy, we leave the market value to the market itself, with our live auction platform.  

Knowing Your 4 C’s

This is the most important step in the diamond grading process, so when buying or selling a diamond, it’s good to at least have an idea of what each element means. 

Carat - This most basic and familiar aspect of diamond value. Carat refers to the size of the diamond, correlating with the weight of it. For your reference, 1 carat equals .2 grams. 

Color - To an untrained eye, most diamonds appear colorless, or white when in fact, it is common for diamonds to have a slight brown or yellow tint. Color grades sit on a scale from D-Z with D being completely void of color and Z having a yellow tone. 

Cut - This is commonly misunderstood as the shape of the diamond. While there are several shapes that hold different value due to popularity at any given time, it is not entirely related to the quality of the cut. Standard diamond cuts are; Point cut, Table cut, Old Single cut, Mazarin cut, Peruzzi cut, and old European cut. Each cut varies with the proportions and angles of each facet. 

Clarity - Since assessing quality includes examining internal and external flaws, it is not easy to determine a diamond’s clarity with the naked eye. When an evaluator examines a diamond, they must use special tools in order to see blemishes and inclusions (flaws inside the diamond). A diamond that is flawless does not have any scratches, blemishes, inclusions, or clouds. This makes them very rare and valuable.
