Understanding the Cost of a One Carat Princess Cut Diamond

When it comes to purchasing a diamond, one of the most common questions is: “How much is a one carat princess cut diamond?” This question is vital for both first-time buyers and seasoned collectors who wish to add this stunning gemstone to their collection. The price of a one carat princess cut diamond can vary significantly based on several key factors, including the diamond’s quality, the market conditions, and where the diamond is purchased. This article aims to provide a comprehensive guide to understanding the cost of a one carat princess cut diamond, covering all aspects from the 4 Cs to the influence of market dynamics.


The Appeal of Princess Cut Diamonds

Before delving into the specifics of how much is a one carat princess cut diamond, it is essential to understand why the princess cut is so popular. The princess cut, known for its square or rectangular shape with pointed corners, offers a modern and stylish alternative to the traditional round brilliant cut. This cut is renowned for its exceptional brilliance and fire, second only to the round cut in terms of light performance. The sharp lines and contemporary aesthetic make it a favored choice for engagement rings and fine jewelry.


The 4 Cs and Their Impact on Price

The primary factors influencing the cost of a one carat princess cut diamond are known as the 4 Cs: Carat, Cut, Color, and Clarity. Each of these elements plays a critical role in determining how much is a one carat princess cut diamond.

Carat Weight

Carat weight is a measure of the diamond’s size. A one carat diamond is equal to 200 milligrams or 0.2 grams. While the term “one carat” indicates the weight, it does not address the diamond’s quality. The price of a one carat princess cut diamond can vary based on the other three Cs. Typically, larger diamonds are rarer and, therefore, more expensive. However, two diamonds of the same carat weight can have vastly different prices depending on their cut, color, and clarity.


The cut of a diamond is crucial as it affects the stone’s brilliance and sparkle. A well-cut princess diamond will reflect light beautifully, enhancing its visual appeal. The precision of the cut, including the proportions and symmetry, can significantly impact the price. When considering how much is a one carat princess cut diamond, a premium cut can command higher prices due to the labor and skill required to achieve optimal brilliance.


Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). Colorless diamonds are the most desirable and, thus, more expensive. For a one carat princess cut diamond, slight variations in color can make a notable difference in price. Color grades D, E, and F are the most sought after, while grades G to J offer a good balance between quality and cost for those mindful of their budget.


Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. The clarity scale ranges from Flawless (no inclusions visible under 10x magnification) to Included (inclusions visible to the naked eye). Higher clarity grades mean fewer imperfections, which typically increases the price. When evaluating how much is a one carat princess cut diamond, diamonds with higher clarity grades such as VVS (Very, Very Slightly Included) or VS (Very Slightly Included) are generally more expensive than those with lower clarity grades.

Additional Factors Affecting Price

Beyond the 4 Cs, several other factors can influence how much is a one carat princess cut diamond. These include fluorescence, certification, and the diamond’s overall market demand.


Fluorescence refers to the diamond’s reaction to ultraviolet light, which can cause the stone to emit a bluish glow. While fluorescence can affect the appearance of a diamond, it can also influence its price. Some buyers prefer diamonds with no fluorescence, believing they have better quality, while others might not mind or even prefer a slight fluorescence. This preference can affect how much is a one carat princess cut diamond.


Diamonds are often accompanied by a grading report from a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the American Gem Society (AGS). Certification provides an objective assessment of the diamond’s quality, covering the 4 Cs and other attributes. A certified one carat princess cut diamond is typically more expensive than a non-certified one due to the assurance of quality and authenticity.

Market Demand

The price of diamonds can also be influenced by market trends and consumer demand. Economic conditions, fashion trends, and cultural preferences can cause fluctuations in how much is a one carat princess cut diamond. For instance, if princess cut diamonds become particularly fashionable, their prices may rise due to increased demand.

Where to Buy: Retail vs. Online

The venue from which you purchase your diamond can significantly affect how much is a one carat princess cut diamond. Traditional brick-and-mortar jewelry stores often have higher overhead costs, which can be reflected in their prices. On the other hand, online retailers typically offer more competitive pricing due to lower operational costs. Here’s a closer look at the pros and cons of each option:

Retail Stores


Personal interaction with jewelers.

Ability to see and feel the diamond in person.

When determining how much is a one carat princess cut diamond, it is essential to consider these factors and choose a purchasing method that aligns with your preferences and budget.
