What is a lab grown oval diamond?

Introduction to Lab Grown Oval Diamonds

The world of diamonds has been revolutionized by the introduction of lab grown diamonds, and oval cuts are among the most popular choices for those seeking a blend of brilliance and uniqueness. A lab grown oval diamond is a man-made diamond created in controlled laboratory conditions that mimics the natural diamond-growing process but in a fraction of the time. These diamonds possess the same physical, chemical, and optical properties as natural diamonds, making them indistinguishable to the naked eye and even to most gemological tools.

The oval shape, characterized by its elongated form with rounded ends, has gained immense popularity for engagement rings and other fine jewelry pieces. At Raad Jewelers, we’ve seen a significant increase in customers seeking lab grown oval engagement rings due to their unique advantages. These diamonds offer the perfect blend of classic elegance and contemporary appeal, making them an excellent choice for those who want something slightly different from the traditional round brilliant cut.

Unlike natural diamonds that form over billions of years deep within the Earth, lab diamonds are created in just a few weeks or months, allowing for greater availability and more ethical sourcing. This modern approach to diamond creation has opened up new possibilities for consumers who value sustainability and ethical considerations in their jewelry purchases while still desiring the timeless beauty of a diamond.

The Creation Process: How Lab Grown Oval Diamonds Are Made

Lab grown diamonds, including oval shapes, are created using two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both processes start with a tiny diamond seed that serves as the foundation for the new diamond to grow.

In the HPHT method, carbon is subjected to extreme pressure (approximately 1.5 million pounds per square inch) and high temperatures (around 2,700°F) to recreate the natural conditions under which diamonds form within the Earth. This process essentially compresses carbon atoms to form the crystalline structure of a diamond. The CVD method, on the other hand, involves placing a diamond seed in a sealed chamber filled with carbon-rich gas. When the gas is heated, carbon atoms separate from the gas and layer onto the seed, gradually building a diamond crystal.

After the rough lab diamond is formed, it undergoes cutting and polishing by skilled artisans to create the distinctive oval shape. This process requires precision and expertise to maximize the diamond’s brilliance while maintaining the ideal proportions that make oval diamonds so appealing. The cutting process for oval lab grown diamonds is identical to that used for natural diamonds, requiring the same skill and attention to detail.

What makes lab grown diamonds remarkable is that they possess the same carbon crystal structure as natural diamonds. This means they exhibit identical hardness (10 on the Mohs scale), refractive properties, and fire. Even experienced gemologists typically need specialized equipment to distinguish between a lab grown diamond and a mined one.

Why Choose the Oval Shape?

The oval cut diamond offers several unique advantages that have contributed to its rising popularity, especially in lab grown diamond engagement rings. First introduced in the 1960s, the oval cut combines the brilliance of a round diamond with an elongated shape that creates a slimming effect on the finger.

One of the most appealing aspects of oval engagement rings is their ability to appear larger than other diamond shapes of the same carat weight. This is because the elongated shape maximizes the diamond’s surface area, creating an impressive visual presence. For those interested in 2 carat lab grown diamonds or even 3 carat lab grown diamonds, choosing an oval cut can make these impressive stones appear even more substantial.

The oval shape also offers excellent versatility in jewelry design. It pairs beautifully with various setting styles, from classic solitaires to elaborate halo designs. Lab grown oval engagement rings can be set in east-west orientation (with the oval laying horizontally) for a contemporary look or in the traditional north-south orientation for a classic appearance.

Additionally, oval diamonds are less prone to chipping than shapes with pointed corners, such as marquise or pear cuts. This makes them a practical choice for everyday wear, particularly in items like lab diamond rings that might experience more exposure to potential damage. The smooth, rounded edges of oval diamonds contribute to their durability while maintaining their elegant appearance.

Lab Grown vs. Natural Oval Diamonds: A Detailed Comparison

When comparing lab grown oval diamonds to their natural counterparts, it’s important to understand that they are chemically, physically, and optically identical. Both are composed of crystallized carbon arranged in the same structure, which gives diamonds their exceptional hardness and brilliance. However, there are several key differences worth considering.

The most significant difference lies in their origin and environmental impact. Natural diamonds are formed over billions of years deep within the Earth and are extracted through mining, which can have considerable environmental consequences. In contrast, lab diamonds are created in controlled environments with a substantially smaller carbon footprint. For environmentally conscious consumers, lab diamond rings featuring oval cuts offer a more sustainable choice.

Price is another major differentiator. Lab grown diamond rings typically cost 30-40% less than comparable natural diamond jewelry. This price advantage allows customers to purchase larger stones or higher-quality diamonds within the same budget. For example, you might be able to afford a 2 carat lab created diamond for the same price as a 1-carat natural diamond, or even explore options like a 4 carat lab grown diamond that would be prohibitively expensive in natural form.

In terms of availability, lab grown diamonds offer more options, particularly in larger carat weights and higher clarity grades. Since their production is controlled, it’s easier to create lab grown diamonds with specific characteristics. This makes it easier to find the perfect oval diamond for your lab created diamond engagement ring without compromising on quality or size.

Quality Factors to Consider When Buying a Lab Grown Oval Diamond

When shopping for a lab grown oval diamond, the same quality factors used to evaluate natural diamonds—the 4Cs (Cut, Color, Clarity, and Carat weight)—apply. However, there are some specific considerations for oval cuts that can help you make an informed decision.

The cut of an oval diamond significantly influences its brilliance and overall appearance. Unlike round diamonds, oval cuts don’t have a standardized cut grading system. However, the ideal length-to-width ratio for an oval diamond typically ranges from 1.3:1 to 1.5:1, depending on personal preference. This proportion ensures the diamond displays the classic oval shape without appearing too narrow or too round. When examining lab grown diamond engagement rings with oval stones, pay attention to symmetry—the two halves of the diamond should mirror each other perfectly.

One characteristic unique to oval diamonds is the “bow-tie effect”—a dark area resembling a bow tie that can appear across the center of the stone due to light reflection patterns. While some degree of bow-tie is present in most oval diamonds, excessive darkening can detract from the diamond’s beauty. At Raad Jewelers, our lab grown diamonds are carefully selected to minimize this effect.

For color, most customers prefer oval diamonds in the near-colorless range (G-J) as they offer excellent value while appearing white to the naked eye. Clarity is another important factor—because of their larger table (top surface), inclusions may be more visible in oval diamonds than in other cuts. We recommend SI1-VS2 clarity grades for lab diamonds to ensure eye-clean appearance while maintaining reasonable pricing.

Carat weight affects both the size and price of your diamond. Whether you’re looking for a 1 carat lab grown diamond or dreaming of a 5 carat lab grown diamond, remember that oval cuts appear larger than round diamonds of the same weight, giving you more visual impact for your investment.

Setting Options for Lab Grown Oval Diamonds

The versatile nature of oval diamonds makes them compatible with various setting styles, each highlighting different aspects of these beautiful stones. When choosing a setting for your lab grown diamond ring, consider both aesthetics and practicality.

Solitaire settings showcase the oval diamond as the star of the show. This timeless design features a single diamond held by prongs, allowing maximum light exposure for optimal brilliance. For lab diamond engagement rings, a six-prong setting provides secure support for the elongated shape of an oval diamond while preserving its elegant outline.

Halo settings surround the center oval diamond with a circle of smaller diamonds, amplifying the overall sparkle and making the center stone appear larger. This setting style is particularly popular for lab created diamond engagement rings as it maximizes the impressive visual presence that oval cuts naturally possess. Three-stone settings pair the oval center diamond with side stones, often in complementary shapes like round or pear, creating a meaningful representation of a couple’s past, present, and future.

Bezel settings, which encircle the diamond with a metal rim, offer excellent protection for the stone, making them ideal for active lifestyles. This modern setting style can create a sleek, contemporary look for lab created diamond rings.

For those who appreciate vintage aesthetics, oval diamonds set in detailed vintage-inspired settings with milgrain detailing and intricate metalwork create a romantic, timeless appeal. These settings pair beautifully with lab diamond wedding bands in complementary styles.

Beyond rings, oval lab grown diamonds are stunning in other jewelry pieces as well. They make eye-catching center stones in lab created diamond necklaces and pendants, while graduated oval diamonds create elegant lab grown diamond tennis necklaces.

Cost Benefits of Lab Grown Oval Diamonds

One of the most compelling advantages of choosing lab grown oval diamonds is their significant cost savings compared to natural diamonds. On average, lab diamonds cost 30-40% less than their natural counterparts of equivalent quality, allowing customers to maximize their budget without compromising on beauty or quality.

This price advantage becomes particularly evident when considering larger carat weights. While a 2 ct lab grown diamond in oval shape may be within reach for many consumers, a natural diamond of the same size might be prohibitively expensive. This cost difference enables
