A 0.25 Carat diamond is worth between $275 to $440. However, this price is subject to fluctuation and change based on market factors. When it comes to evaluating a diamond’s worth, the following is taken into consideration:

  • Published weekly at midnight each Thursday, the Rapaport Report is the primary source for current diamond pricing information.

  • Cut, Clarity, Carat, and Color: the Four Cs of diamond quality will highly influence the price and value of a diamond.

  • Diamonds that have received certification from either GIA (Gemological Institute of American) or  AGS (American Gem Society) are considered reliable.

Industry-Standard Diamond Pricing Information in the Rapaport Report

Diamond merchants and jewelers rely on the in-depth Rapaport Price List as their primary source for current diamond price information. Dealers use this data as a guideline when evaluating diamond prices.

Because this resource lists the high cash asking prices for better diamonds and Rapaport Specification 2 diamonds, they may be significantly more than actual transaction prices. In fact, it’s common for those in the diamond trade to buy and sell diamonds at a discounted price from the list.

Nonetheless, when certain qualities are in limited supply or are in speculative demand, the  prices they are bought and sold at could be at a premium compared to the list. However, these premiums are typical only for very fine cut, large diamonds.

4Cs of Diamond Quality are Accurate Price Indicators

All diamonds are not created equally. Therefore, a standardized list of prices is not enough to evaluate a diamond’s actual worth. Rather, the actual diamond’s characteristics need to be taken into account, which includes: Carat, Cut, Clarity, and Color.

Carat: How Much does the Diamond Weigh?

When it comes to diamond terminology, the term carat refers to the actual weight of the diamond. While this measurement usually gives a general indication of the size of the diamond, the carat number does not always accurately portray the size.

A diamond that has been meticulously cut will reflect light out of the top which may cause it to appear bigger and brighter than its carat weight. Poorly-cut diamonds are bottom heavy and appear smaller than the actual carat weight. In fact, a diamond with a lower carat weight but a higher quality cut will often appear larger than a diamond that has been poorly cut that carries a greater carat weight.

Cut: How Sparkly is the Diamond?

Because the way a diamond is cut has the biggest influence on its sparkle factor and overall appearance, it’s often considered the most important feature of a diamond.

The top of the diamond (also known as the table) is where the light is reflected outward. How the stone has been cut will determine how strong this effect will be. When the cut is narrow or shallow, the light is not reflected out of the top of the diamond, rather out of the bottom. A diamond that has been cut too deeply will lose light from the sides of the gem.

Clarity: How Many Imperfections are in the Diamond?

Most diamonds will include medium and minuscule imperfections. Clarity is the measure of the size and quantity of these imperfections. However, these exist in nearly every single diamond and are typically microscopic in nature and cannot be seen or alter the image of the diamond.

Out of the 4Cs of diamond quality, clarity is considered the easiest to understand, and has the least amount of influence on the appearance of the diamond. Diamonds with the lowest amount of imperfections achieve the highest clarity grades.

Color: How White is the Diamond?

While it’s referred to as color, the color grading of a diamond actually measures the whiteness, or lack of color present in the stone. Z is the lowest grade and includes the most coloration and D is the highest possible grade with the least amount of coloration.

Coming in just after the cut, color is considered the second most important factor when choosing a diamond.

Has the Diamond Received Official Certification?

Diamonds that  have been certified by the GIA or AGS are considered reliable. These officially-recognized institutions use consistent and systematic methods of grading diamonds, which gives buyers more confidence in their purchase.

Furthermore, it’s important to keep in mind that when you buy a certified diamond it should not cost more than other diamonds. Rather, this certification is intended to assure the buyer that the diamond’s official grade is true and accurate. Therefore, you are getting exactly what you paid for.
