About Oval Cut Lab Grown Diamonds
Oval cut lab grown diamonds offer the perfect balance of timeless elegance and modern brilliance. With their elongated silhouette and exceptional light performance, oval cut diamonds have surged in popularity to become one of the most sought-after diamond shapes in the world. At Variation, our certified collection brings you hundreds of ethically created oval lab grown diamonds at prices that simply cannot be matched by mined stones.
What Is an Oval Cut Diamond?
The oval cut diamond is a modified brilliant cut, featuring 56 to 58 facets arranged to maximize light reflection, fire, and scintillation. First developed in the 1950s by diamond cutter Lazare Kaplan, the oval cut combines the brilliance of the classic round cut with a distinctive elongated shape that creates a larger visual appearance per carat than almost any other diamond shape.
Its symmetrical, elongated form is universally flattering — creating the illusion of longer, more slender fingers when worn as a ring — making it one of the most popular choices for engagement rings worldwide.
Why Choose Lab Grown Over Mined Oval Cut Diamonds?
Lab grown diamonds are physically, chemically, and optically identical to mined diamonds. The only difference is their origin — and that difference works entirely in your favor.
- Up to 80% more affordable than equivalent mined diamonds
- Conflict-free and ethically created with zero mining impact
- Eco-friendly — significantly lower carbon footprint than earth-mined stones
- IGI/GIA certified — graded to the same strict standards as natural diamonds
- Same hardness, same brilliance, same forever — a lab grown diamond is a real diamond
Choosing an oval cut lab grown diamond means you get a larger, more brilliant stone for the same budget — without compromise.

How to Choose the Right Oval Cut Lab Grown Diamond
1. Choose the Right Length-to-Width Ratio
The length-to-width ratio defines how elongated your oval diamond appears. A ratio of 1.35–1.50 is considered the classic, most flattering oval shape. Below 1.30 appears rounder; above 1.50 appears more narrow and elongated. Choose based on personal preference and finger length.
2. Watch for the Bowtie Effect
Most oval cut diamonds display a bowtie — a dark shadow across the center of the stone caused by light leakage. A slight bowtie is normal and acceptable; a prominent bowtie significantly reduces brilliance. Always view a stone in video or in person before purchasing to assess bowtie visibility.
3. Prioritize Cut Quality
Unlike round diamonds, oval cuts do not receive an official cut grade on their certificate. Instead, assess cut quality through symmetry, polish, and length-to-width ratio. Choose Excellent symmetry and Excellent or Very Good polish for the best light performance.
4. Color Recommendations
Oval cut diamonds retain color slightly more than round cuts due to their larger surface area. For white gold or platinum settings, choose D–F color grades. For yellow or rose gold settings, G–H color grades pair beautifully and offer excellent value.
5. Clarity Sweet Spot
VS1–VS2 clarity is the sweet spot for oval cut diamonds — eye-clean to the naked eye while offering significant savings over Flawless grades. Oval cuts hide inclusions better than step cuts, making VS2 an excellent value choice.

Frequently Asked Questions
Are oval cut lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds. They share the same physical, chemical, and optical properties as mined diamonds and are certified by the same internationally recognized grading laboratories.
Do oval cut diamonds look larger than round diamonds?
Yes — oval cut diamonds typically appear 10–15% larger than a round diamond of the same carat weight due to their elongated shape and larger surface area. This makes them an excellent choice for buyers seeking maximum visual size.
What is the bowtie effect in oval diamonds?
The bowtie effect is a dark shadow that appears across the center of an oval diamond caused by light leakage. A slight bowtie is normal; a strong bowtie reduces brilliance significantly. Always view the stone in video or in person before purchasing.
What is the best length-to-width ratio for an oval diamond?
A length-to-width ratio of 1.35–1.50 is considered the most flattering and classic oval shape. Personal preference plays a role — a lower ratio appears rounder while a higher ratio appears more elongated.
Are lab grown oval cut diamonds cheaper than mined ones?
Yes — priced up to 80% less than an equivalent mined diamond, with no difference in beauty, durability, or certification.
