Diamonds that are not yet set in jewelry are inarguably every gem lover’s wish because it provide a leeway and liberty when creating tailored jewelry. However, knowing the price tag that accompanies these beautiful pieces of stone is as complex as the brilliance of diamonds. For beginners the aspects of this article will help you understand the cost of loose diamonds while the old-timers will not find anything new here.

What are Loose Diamonds?

Uncut diamonds are simply exactly that – diamonds that have not been incorporated into jewelry pieces. Such loose diamonds are usually bought for own use in the making of other products such as jewelry or for business purposes like acting as investments. They offer a unique advantage: It also allows buyers some measure of checking the quality of the diamond without the presence of a setting that may in some way obscure the stone’s quality.

Factors Affecting the cost of the Diamonds

The following are the factors that define the cost of loose diamonds. The primary ones are known as the Four Cs: Four characteristics depicted as ‘Carat’, ‘Cut’, ‘Color’ and ‘Clarity’. It is about time we look into each of these aspects in detail.

Carat Weight and the influence that it has on Cost

Explanation of Carat

It is worth noting that the diamond size is determined by Carat weight. It was established that 1 carat is equal to 200mg. Generally, bigger diamonds are scarcer and, as a result, costlier, however, the difference in cost is not proportional strictly. A two carat diamond is not only two times the size of a one carat diamond, which would merely mean the price is two times as high, but it is much more than that.

Price Per Carat

The costs also rise as the size of the diamond goes up where one can cost up to $10,000 per carat. There could be for example, a one carat diamond that can be as expensive as $5000 but a two carat diamond is likely to cost $20000 or more. Even if the rare and bigger diamond costs a few million dollars more than other diamonds, it is because such a diamond is very rare.

Cut Quality and Its Effect on Price

Importance of a good cut

The cutting of the diamond determines the general magnificent light reflection and appearance of the diamond. Good shaped diamonds will yield bright reflection if light is being irradiated towards it hence making it to be more attractive as well as worthy a higher price in the market. The cut is the singular Four C that is not dictated by nature and therefore stands out as a vital factor that defines a diamond’s beauty.

How Cut influences Sparkle and Value

A poor cut again can make a high carat diamond look less sparkling, on the other hand, an excellent cut can make a small shaped diamond attractive to look at. Thus, diamonds with excellent or very good cut grades will cost more than diamonds with poor cut grades.

Color grading and how it impacts on the price

Diamond Color Scale

Diamonds are categorized based on color ranging from D, which is the highest color grade, to Z, which is light yellow or brown in appearance. The naturally white diamonds are rarer and are more costly than the colored ones. Thus, while yellow diamonds are famous, fancy-colored diamonds that are blue or pink, for instance, can cost even more due to their scarcity.

Most Popular Brokers and Their Fees

Loose diamonds of the lowest color grade, D-F are the most valuable. Diamond color ranges from the near colorless Grades G-J that are relatively cheaper than the absolutely colorless Grades D-F but relatively expensive than the noticeable colored Grades K-Z.

Clarity Grading and its role in Pricing

Understanding Clarity Grades

Clarity is established by using concepts of inclusion which are imperfections within the diamond and blemishes that are the imperfection on the surface of the diamond. The clarity scale is from Flawless (FL) to Included (I), though there are intermediary classifications that include Very Slightly Included (VS) and Slightly Included (SI).

Common Inclusions and Blemishes

Impurities to some extent have influence over the brilliance and the monetary worth of diamonds. That is, typical objects are crystals, feathers, and clouds. Most inclusions are so small that they cannot be seen with the naked eye, but they do influence price.

Factors that contribute to the Price of Loose Diamonds


These diamonds have been graded by well recognized laboratories as those of GIA or AGS and will pass on all details of the diamond to the buyer. Certification affects the price determination of a diamond because diamonds that are certified tend to be expensive.


Fluorescence is the phenomenon that entrails the diamond’s emission of light when subjected to ultraviolet light. There are customers who avoid fluorescence, while others are alright with it hence impacting the price.


Price also depends on the shape of the diamond where a diamond in the shape of a round cut costs more than any other shape of the diamond. Round jewels are more costly than the other shaped jewels because more people prefer them, and it takes great effort to cut them. It must be added that some styles such as the oval, pear, or marquise settings can be less expensive.

How to save cost when buying Loose Diamonds

Buying Tips
