5 Factors That Determine The Price of Loose Diamonds

How to sell loose diamonds, and how are they priced? No, we are not talking about diamond jewelry of any form. Instead, in this article, we will be discussing loose diamond pricing and the factors that play a role in loose diamond prices

1. Diamond certifications

It is a prominent factor that impacts loose diamond pricing significantly. You must have heard of GIA certifications. The Gemological Institute of America grades and assesses diamonds. Since they are a world-class laboratory with the highest evaluation standards, GIA diamond certificates are highly coveted. As a result, GIA certificates increase loose diamond pricing.

Apart from GIA, several other renowned laboratories grade diamonds. Each certification consists of a complete, detailed analysis of the diamond. This is useful in figuring out the worth of the diamond. If you are buying loose diamonds with certification, you will inadvertently need to pay a high sum for the certificate. In reverse, if you are selling loose diamonds along with certificates, you stand to earn a high sum of money.

Thus, whether you plan to buy or sell, loose diamonds pricing rests heavily on the diamond certification.   

2. The 4Cs

For accurate grading of diamonds, there is a need for uniformity. Thus, four factors are primarily kept in mind while examining a diamond’s value – clarity, color, carat weight, and cut. These 4Cs determine loose diamond pricing and ascertain whether a diamond has finished or not.

Diamond clarity:

According to GIA, diamond clarity refers to a qualitative metric that grades the visual appearance. Very often, natural diamonds have a host of imperfections and flaws, which compromises their clarity. But sometimes, these imperfections are too minimal to be noticed by the untrained eye. Diamonds that are free from internal blemishes are scarce. Thus, loose diamonds pricing varies based on relief and inclusions present in the stone.

Diamond color:

The color of a diamond plays a significant role when it comes to determining loose diamond pricing. GIA classifies this color factor on a color scale that ranges from “D” to “Z,” where D represents colorless diamonds, and Z signifies diamonds that are yellowish or light brown. Colored diamonds like blue and pink hold high value. A yellowish tint has not considered to be desirable in the case of white diamonds.

Carat weight:

Due to the extreme precision required in weighing diamonds, the fraction of a carat can make a huge difference in loose diamonds pricing. Thus, accurate weighing of a diamond is of great importance in setting loose diamonds pricing.

Diamond cuts:

A cut diamond requires expert craftsmanship and expertise. The proportions and cutting determine the angle at which light enters the diamond. If the light does not enter at the best angle, it will result in a dark and dull appearance, which will negatively impact loose diamond pricing. It is why artisans take special care to cut and shape the diamond in such a way to enhance the light and dark areas. This contrast enhances the sharpness and clarity of the diamond, giving it a crisp and neat look. As a result, well-cut loose diamonds have priced higher.


3. Diamond symmetry and polish

Aside from the 4Cs, factors like diamond symmetry and polish also affect loose diamond pricing, albeit to a lesser extent. In case a diamond is not well-polished, its facets fail to act as mirrors. So, light has not reflected correctly, and the diamond will appear dull and ordinary. Diamonds with extremely poor symmetry will have a clear gloomy appearance. It is because light will not be reflected in the intended manner, making the stone look deformed. 

4. Diamond fluorescence

If you have a good understanding of diamond fluorescence, you will realize that it affects loose diamond pricing. This fluorescence is nothing but a tinted glow emitted by diamonds. The diamond’s fluorescence is heavily dependent on the stone’s color range and has therefore priced accordingly.

5. The big names

The inner workings of the diamond industry are complicated and convoluted. But, it is worth noting that large-scale diamond manufacturers affect loose diamond pricing. Many brands may determine the prices of loose diamonds with hidden charges. Thus, it is safer to go for trusted names that offer a transparent process whether you are buying or selling loose diamonds.


Having reached this point of the article, you must have understood the basics of how loose diamond pricing works. While the issues discussed above are enough to give you a head start in this field, loose diamond pricing has best understood with experts’ guidance. While diamond certificates are key players, testing the fluorescence, clarity, and tint of diamonds is of utmost importance. The slightest of change can heavily affect the loose diamond pricing.
