How to price a diamond with a price list?

Today we will try to understand that price lists are usually produced or two types of diamond shapes:

  • For Round cut diamonds
  • For Pear shaped diamonds

Now, the Pear shaped diamond price list is also used a lot o times for other fancy cut diamonds. Fancy cut diamonds are basically diamonds like the princess cut diamond, the oval cut diamond, the emerald diamond, the heart diamond and so on and so forth!

Fancy shaped Diamonds

In case of other fancy shaped diamonds (apart from the pear shaped diamond) you need to pay special attention to the cut of a stone.

The diamond price list is mainly presented by Rapnet. There you will also be able to find the up-to-date diamond price list. This price list is presented in a table where the values are organized by carat weight color and clarity.

Step 1 in looking at the diamond price list

Before we actually get into the nitty gritty details there is one little thing I still need to mention: You should have a diamond grading report when looking at diamonds. Without it you will be lost and you will not be able to estimate a diamond’s price properly. But in order to do that you will definitely need a diamond grading report!

We recommend to go for a diamond grading report by either GIA or AGS.

The first step is to determine the diamond shape that you want to buy. You have to know your diamond shape to be able to look at the right price list. Only then will you be able to have a look at the most appropriate diamond shape.

Usually, it comes down to the decision between a round cut diamond and another fancy cut diamond

What you also need to be aware of is that diamond prices differ according to to the diamond shape.

Round cut diamonds are the most expensive diamond shape if you look at it per carat weight. You get the most carat weight per dollar for princess cut diamonds. It is also for this reason that princess cut diamonds have recently become so popular!

Step 2 in using a diamond price list

Now, you have to determine the carat weight of the diamond. In order to do so you will simply have to look at the diamond grading report into the carat weight section.

You then have to find the section that responds to the carat weight of your own diamond. If for instance your diamond has a carat weight of 1.26ct you will most likely have to look into the 1.00ct – 1.49ct section of the diamond price list.

One quick tip to save more money: You can save a considerable amount of money by getting a diamond that is just below the threshold to the “next level”. For instance if you were able to get a diamond with 0.99ct it would be considerably cheaper than a diamond with exactly 1.00ct.

The reasons for these sudden price jumps are purely psychological of course. Many people want to buy a diamond that has 1.00ct or 1.5ct and it is for this particular reason that people will try anything to get these particular diamonds.

If you are not like that and you are fine with buying a diamond with say 0.99ct or 1.49ct you can save a whole lot of money.

Now, to be really honest with you: It will be a challenge to find such diamonds anyway. Because it is a very well known fact that diamond cutters will try to cut diamonds on purpose in such a way that they just make it above these psychological marks.

In fact, many diamond cutters will even sacrifice the diamond cut in order to get the diamond above certain thresholds. It is just a sad truth that the average diamond consumer just pays more for certain carat weights!

Step 3 when using the diamond price list

Now, you will have to find the quality grade of your diamond and find the corresponding price!

There will be two scales you will need to check for every table. The one is the scale for diamond color and the other one is the scale for diamond clarity! Both must match the diamond characteristics of your own diamond!

You can see an example of a Rapaport Diamond Price List below. You can enlarge the image by clicking on it:

Step 4 when using the Rapaport price list

Now you will have to do a simple calculation.

You will have to multiply the price per carat by the carat weight that your diamond has. This way you will end up with the correct diamond price that you should pay for a diamond with these specific 4C parameters!

This way you don’t end up paying too much for your diamond!

We recommend that you use the diamond price list every time before making a purchase!
