About Oval Cut Lab Grown Diamonds
Oval Cut Lab Grown Diamonds – Balanced Proportions, Refined Brilliance
Oval cut lab grown diamonds are distinguished by their elongated shape and smooth, continuous outline. Designed to deliver strong brilliance while offering a refined visual profile, the oval cut combines the optical performance of a round diamond with a more contemporary silhouette.
At Variation, each oval cut lab grown diamond is selected based on strict criteria for symmetry, proportion, and optical balance. Featuring IGI-certified grading, our diamonds meet internationally recognised standards and are trusted by customers across Germany and Europe.
What Are Oval Cut Lab Grown Diamonds?
Oval cut lab grown diamonds are genuine diamonds created using advanced CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) technology. They are chemically, physically, and optically identical to mined diamonds.
The oval cut features an elongated facet arrangement derived from the round brilliant cut, designed to maximise light return while creating a visually balanced, lengthened appearance.
Key Characteristics
100% real lab grown diamonds composed of pure carbon
Identical hardness and optical properties to mined diamonds
Elongated outline with smooth, symmetrical curves
Strong brilliance driven by a modified brilliant-cut facet structure
IGI-certified diamonds for verified quality and transparency
Oval cut lab grown diamonds are valued for their balance of brilliance, proportion, and visual elegance.

Frequently Asked Questions
Why are oval cut lab grown diamonds so popular? +
Oval cut diamonds offer an elegant, elongated shape that creates exceptional brilliance
and gives the illusion of a larger size. They are timeless, flattering on all fingers,
and beautifully modern while still feeling classic.
Do oval diamonds look larger than round diamonds of the same carat weight? +
Yes. Because of their elongated shape and larger surface area, oval diamonds look visibly
bigger than round diamonds of the same carat size, making them a popular choice for
buyers who want maximum presence and value.
What is the “bow-tie effect” in oval cut diamonds? +
The bow-tie effect refers to a darker shadow seen across the center of some oval diamonds.
With well-cut lab grown diamonds, the bow-tie is minimal or nearly invisible. High-quality
cut, polish, and symmetry help ensure balanced, even sparkle.
What is the best length-to-width ratio for oval diamonds? +
Most buyers prefer ratios between 1.30 and 1.40, which create a balanced, elegant shape.
Slimmer ratios (1.45+) appear more elongated, while shorter ratios (1.25–1.30) look wider
and more vintage-inspired.
Are oval cut lab grown diamonds good for engagement rings? +
Oval diamonds have become one of the most popular choices for engagement rings due to
their romantic shape, bright sparkle, and ability to make fingers look longer and slimmer.
They work beautifully in solitaire, halo, hidden-halo, and 3-stone settings.
Do oval diamonds hide inclusions well? +
Yes. Oval diamonds reflect light very well, helping mask small inclusions. Most customers
choose VVS–VS clarity for an excellent balance of beauty and value, especially in lab grown diamonds.
What settings look best with oval cut diamonds? +
Oval diamonds pair beautifully with solitaire, halo, hidden-halo, east-west, and 3-stone
designs. Their elongated shape gives them versatility and a naturally graceful appearance.
Are oval cut lab grown diamonds certified by IGI or GIA? +
Yes. Oval cut lab grown diamonds can be certified by reputable labs such as IGI and GIA,
ensuring complete transparency of cut, clarity, color, carat weight, and growth method.
What colors look best in oval cut lab grown diamonds? +
Because ovals have an open, larger surface area, many buyers prefer D–H color for a bright,
white appearance. Lab grown diamonds make premium color grades more affordable.
Do oval cut lab grown diamonds come in various sizes? +
Yes. Oval diamonds are available from under 0.50 carat to 10+ carats, offering exceptional
value and impressive visual size due to their elongated shape.
