What Are the Quality Standards for Lab Created Oval Diamonds?

Diamonds are one of the most sought-after and valuable gemstones in the world. With advancements in technology, lab-created diamonds have become a popular alternative to natural diamonds. Among the various shapes of lab-created diamonds, the oval diamond is a classic and elegant choice. However, when it comes to purchasing lab-created oval diamonds, it is essential to understand the quality standards that distinguish a superior stone from a subpar one.

Understanding the 4Cs of Lab-Created Oval Diamonds

The 4Cs - cut, color, clarity, and carat weight - are the standard parameters used to evaluate the quality of diamonds, both natural and lab-created. When it comes to lab-created oval diamonds, each of these factors plays a crucial role in determining the overall quality and value of the stone.

Cut

The cut of a diamond refers to the quality of the craftsmanship in shaping the stone. In the case of oval diamonds, the cut is particularly important as it directly impacts the diamond's brilliance and fire. A well-cut oval diamond will exhibit excellent sparkle and radiance, making it a stunning choice for an engagement ring or other jewelry pieces.

When evaluating the cut of a lab-created oval diamond, look for symmetry and proportionality. The oval shape should be elongated with a well-defined outline and graceful curves. The facets should be meticulously placed to enhance the diamond's brilliance and dispersion of light. Additionally, the diamond should have excellent polish to ensure maximum shine and luster.

Color

The color of a diamond refers to the presence of any tint or hue within the stone. In the case of lab-created diamonds, colorless stones are highly prized for their purity and brightness. However, oval diamonds are unique in that they can showcase a range of colors, from icy whites to warm yellows and even fancy hues like pink and blue.

When selecting a lab-created oval diamond based on color, consider your personal preference and style. Some individuals prefer the classic look of a colorless diamond, while others are drawn to the unique charm of a colored stone. Regardless of your choice, ensure that the color is evenly distributed throughout the diamond, with no visible imperfections or discolorations.

Clarity

Clarity refers to the presence of any internal or external imperfections within a diamond. In the case of lab-created oval diamonds, clarity plays a significant role in determining the stone's overall beauty and value. A diamond with high clarity will appear flawless to the naked eye, while a stone with lower clarity may have visible inclusions or blemishes.

When assessing the clarity of a lab-created oval diamond, look for stones that are eye-clean, meaning that any imperfections are not visible without magnification. Inclusions near the center or edges of the diamond should be minimal and non-obtrusive. Opt for diamonds with high clarity grades to ensure maximum brilliance and transparency.

Carat Weight

Carat weight refers to the size of a diamond, with one carat equaling 200 milligrams. In the case of lab-created oval diamonds, carat weight is a personal preference based on the size and style of jewelry you desire. Oval diamonds are known for their elongated shape, which can create the illusion of a larger size compared to other diamond shapes.

When choosing a lab-created oval diamond based on carat weight, consider your budget and the desired appearance of the stone. Keep in mind that larger diamonds will typically have a higher price tag, so it's essential to strike a balance between size and quality. Opt for a diamond that suits your style and preferences while ensuring that it meets the quality standards for cut, color, and clarity.

Setting Quality Standards for Lab-Created Oval Diamonds

In addition to the 4Cs, there are specific quality standards that apply specifically to lab-created oval diamonds. These standards are essential for ensuring that you are purchasing a superior-quality stone that will stand the test of time and retain its beauty for years to come.

Ethical Sourcing

One of the key quality standards for lab-created oval diamonds is ethical sourcing. Unlike natural diamonds, lab-created diamonds are produced in controlled environments using advanced technology. This means that lab-created diamonds are inherently conflict-free and do not contribute to any ethical concerns or environmental harm.

When purchasing a lab-created oval diamond, inquire about the sourcing practices of the diamond manufacturer to ensure that the stone is produced sustainably and responsibly. Look for certifications from reputable organizations that verify the ethical and environmental standards of the diamond, such as the Diamond Foundry or the International Gemological Institute (IGI).

Certification and Grading

Another essential quality standard for lab-created oval diamonds is certification and grading. A reputable diamond laboratory will evaluate the quality of a diamond based on the 4Cs and issue a certification report that outlines the diamond's characteristics and attributes. This certification serves as a guarantee of the diamond's quality and authenticity.

When purchasing a lab-created oval diamond, always request a certification report from a trusted diamond laboratory such as the Gemological Institute of America (GIA) or the American Gem Society (AGS). The certification report should detail the diamond's cut, color, clarity, and carat weight, as well as any additional information about the diamond's provenance and characteristics.

Durability and Longevity

The durability and longevity of a lab-created oval diamond are essential quality standards to consider when selecting a stone for your jewelry piece. Lab-created diamonds are known for their hardness and resistance to scratches, making them an ideal choice for everyday wear. However, it is essential to ensure that the diamond is securely set in a high-quality metal setting to prevent any damage or loss.

When purchasing a lab-created oval diamond, choose a setting that complements the stone and provides maximum protection. Opt for metals like platinum or gold that are durable and hypoallergenic, ensuring that your diamond will remain secure and beautiful for years to come. Additionally, consider adding a protective coating to the diamond's surface to enhance its longevity and shine.

Brilliance and Fire

The brilliance and fire of a lab-created oval diamond are key quality standards that define the stone's beauty and allure. Oval diamonds are known for their unique sparkle and radiance, which is enhanced by the diamond's cut and proportions. A well-cut oval diamond will capture and reflect light, creating a dazzling display of colors and scintillation.

When selecting a lab-created oval diamond based on brilliance and fire, look for stones with excellent cut grades that maximize light performance. The oval shape should be symmetrical and well-proportioned, with carefully placed facets that enhance the diamond's sparkle and dispersion of light. Opt for diamonds with high polish and symmetry ratings to ensure maximum brilliance and fire.

Summary

In conclusion, lab-created oval diamonds are a stunning and elegant choice for those seeking a high-quality and sustainable alternative to natural diamonds. When selecting a lab-created oval diamond, consider the 4Cs - cut, color, clarity, and carat weight - as well as specific quality standards for ethical sourcing, certification and grading, durability and longevity, and brilliance and fire. By understanding these quality standards and choosing a diamond that meets your preferences and style, you can ensure that you are investing in a superior-quality stone that will bring joy and beauty for generations to come.
