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.
