1 Clarity
It is common for diamonds with external and internal flaws. These are also known as blemishes and inclusions. The evaluation of a diamond’s clarity is the number and position of these external and internal flaws. The Gemmological Institute of America uses this scale to assign a clarity grade for each diamond.
Flawless
No inclusions or blemishes can be seen under 10x magnification.
Internally Flawless
There are no inclusions, but some blemishes can be seen under 10x magnification.
Very Small Included
Inclusions may be present but are difficult to see below 10x magnification.
Very Slightly Included
There are minor inclusions that may be difficult to see below 10x magnification.
Lightly Included
Inclusions can be seen under 10x magnification.
Included
Inclusions, They are visible under 10x magnification and can impact the diamond’s appearance.
Although the grade-to-grade differences may not be obvious to the untrained eye, they can still impact its price. The most valuable are those with a higher clarity score, but they are extremely rare.
2 Cut
The cut is often referred to as the shape of a diamond. However, it should not be confused with. The cut is what makes the diamond shine and sparkle. The shape describes the form of the diamond. While brilliant round diamonds are the only cut grade the GIA assigns, retailers may use their grading system to assess other shapes.
This is how the diamond’s cut grade is evaluated:
- Brilliance
- Fire
- Scintillation
- Weight ratio
- Symmetry
The cut of a diamond can make a big difference in its value.
3 Carat
A carat is a unit that measures and is used to indicate the diamond’s weight. A carat equals 0.20 grams or 0.007 pounds.
Larger diamonds are rarer, so prices for larger diamonds tend to increase with an increase in carat.
The cost of a diamond does not always increase with its size. For example, a two-carat diamond won’t necessarily be twice as expensive as a one-carat diamond. Carat is one of many factors that can affect a diamond’s price. Therefore, other factors should be considered when determining a diamond’s value.
4 Shape
The shape is another factor that influences the price of a diamond. While prices may vary depending on the shape, the round is the most costly. Some shapes are Round and Radiant.
How does the shape of a diamond impact its price? When cutting diamonds, cutters may lose some of the original stone. The amount of waste will depend on the shape.
The round shape is more expensive than the. This is because a lot of the original diamond gets lost when cut. Making them more affordable, less is lost when cutting other shapes of the diamond.
5 Fluorescence
A little over 30% of diamonds exhibit fluorescence. This means they emit a soft light when exposed to ultraviolet (UV2) light.
Fluorescence has a positive and negative impact on the price of a diamond. A diamond with a low-colour grade can have its bluish glow overpower the yellowish-brown hue, rendering it colourless. This is why the fluorescent effect can increase the value of these diamonds.
In near or colourless diamonds, fluorescence can cause a slightly cloudy or oily appearance. This can make the diamond less attractive and reduce its value.
6 The GIA Diamond Grading Report
The cut of the diamond, colour, clarity, shape and fluorescence will be provided by retailers. It is in your best interests to verify a Diamond’s information. You can do this by viewing the GIA Diamond Grading report.
This report provides a clear and easy-to-understand breakdown of this information. This report includes Carat weight, colour grade, clarity grade (round diamonds only), symmetry, fluorescence, proportions, location of inclusions and blemishes, and Inscriptions (if any).
Before purchasing a stone, it is important to read the report thoroughly. Brilliance provides this report for all lost diamonds.
