What Factors Determine the Value of Oval Lab Diamonds?


Factors That Determine the Value of Oval Lab Diamonds


Diamonds have always been highly coveted and valued gemstones, symbolizing elegance, luxury, and everlasting beauty. However, when it comes to determining the value of a diamond, several factors come into play. Oval lab diamonds, which have gained popularity in recent years, are no exception. In this article, we will delve into the various factors that determine the value of oval lab diamonds. From the 4Cs (carat weight, color, clarity, and cut) to additional considerations such as shape, fluorescence, and market demand, we will help you understand how these elements affect the value of these exquisite lab-grown gemstones.

The 4Cs: Carat Weight, Color, Clarity, and Cut

Carat Weight:

The first and most well-known factor that influences the value of any diamond, including oval lab diamonds, is the carat weight. Carat weight refers to the size or mass of the diamond. Generally, larger diamonds are rarer and, therefore, more valuable. However, it is important to note that carat weight alone does not determine a diamond's value. The other 4Cs play an essential role in assessing the quality and desirability of the stone.


Color is another crucial factor affecting the value of oval lab diamonds. The Gemological Institute of America (GIA) grades diamond color on a scale from D (colorless) to Z (light yellow or brown). Generally, the closer a diamond is to being colorless, the more valuable it is considered. Oval lab diamonds with higher color grades, such as D, E, or F, are more sought after and command higher prices due to their exceptional brilliance and purity.


Clarity refers to the level of imperfections or inclusions within a diamond. The fewer imperfections, the higher the clarity grade, and consequently, the higher the value. The GIA clarity scale ranges from Flawless (no inclusions) to Included (multiple inclusions visible to the naked eye). Oval lab diamonds with higher clarity grades, such as VVS (very, very slightly included) or VS (very slightly included), are more desirable and valuable.


The quality of a diamond's cut greatly influences its value as it affects the stone's brilliance and overall beauty. The cut refers to the diamond's proportions, symmetry, and finish. Oval lab diamonds with excellent cut grades exhibit exceptional fire, brilliance, and scintillation, making them highly valuable. A well-cut oval diamond will reflect light in a captivating manner, captivating the viewer with its shimmering brilliance.

Shape and Symmetry

Beyond the traditional 4Cs, the shape and symmetry of an oval lab diamond also play a significant role in determining its value. Oval diamonds have an elongated shape with rounded edges, which gives them a distinctive, elegant appearance. Symmetry refers to how well the facets of the diamond align and interact with light. Well-proportioned, symmetrical oval lab diamonds are more valuable as they maximize light performance and exhibit an exquisite sparkle.

Fluorescence and Market Demand


Fluorescence is a fascinating characteristic found in some diamonds. It refers to the diamond's tendency to emit a colored glow when exposed to ultraviolet light. Oval lab diamonds with strong or very strong fluorescence may exhibit a hazy or milky appearance, potentially reducing their value. However, faint to medium fluorescence levels can sometimes enhance a diamond's visual appeal, giving it a unique glow.

Market Demand:

Market demand is a crucial factor in determining the value of any diamond, including oval lab diamonds. Trends and consumer preferences can significantly influence prices. Currently, oval diamonds are enjoying a surge in popularity due to their unique shape, which provides an elongating and flattering effect on the finger. This increased demand contributes to higher prices and market value for oval lab diamonds. It is important to stay updated on the ever-evolving diamond market to make informed decisions when purchasing oval lab diamonds.


In summary, various factors contribute to the value of oval lab diamonds. The 4Cs (carat weight, color, clarity, and cut) form the foundation of diamond grading and significantly influence a diamond's worth. Additionally, the shape, symmetry, fluorescence, and market demand all play key roles in determining the value of oval lab diamonds. A combination of these factors, along with personal preferences, should be considered when evaluating the value of an individual oval lab diamond.

As the world of lab-grown diamonds continues to expand, it is essential to understand the value determinants to ensure informed purchasing decisions. Whether you are considering an oval lab diamond for an engagement ring, pendant, or any other piece of jewelry, understanding these factors will help you choose the perfect stone that aligns with your preferences and budget.
