Frequently Asked Questions
What is an oval cut lab grown diamond? +
An oval cut lab grown diamond is an elongated brilliant-cut diamond with rounded edges,
designed to maximise brightness and create the illusion of a larger size. It shares the
same optical and physical properties as a mined oval diamond but is grown using advanced
laboratory technology.
Are oval cut lab grown diamonds real diamonds? +
Yes. Oval cut lab grown diamonds are 100% real diamonds. They are made of pure crystalline
carbon, have the same chemical composition and hardness as mined diamonds, and are graded
using the same 4Cs and international standards.
Why do oval cut diamonds appear larger than round diamonds? +
Oval cut diamonds have an elongated shape and a larger surface area on the top, which
makes them look visually bigger than round diamonds of the same carat weight. This optical
advantage is one of the main reasons buyers love the oval shape.
What is the bow-tie effect in oval cut lab grown diamonds? +
The bow-tie effect refers to a visible shadow in the centre of some oval diamonds caused
by improper facet alignment. Well-cut oval lab grown diamonds minimise this effect by
balancing proportions, symmetry, and facet arrangement for optimal light performance.
What is the ideal ratio for an oval cut lab grown diamond? +
Most buyers prefer an oval length-to-width ratio between 1.30 and 1.50. Lower ratios create
a softer, wider appearance, while higher ratios appear more elongated. The ideal ratio
depends on personal preference and the look you prefer.
Do oval cut lab grown diamonds sparkle as much as round diamonds? +
Yes. Oval cut diamonds use brilliant-cut faceting similar to round diamonds, which allows
them to deliver excellent brilliance, fire, and scintillation. The elongated shape creates
a unique light pattern that many people find elegant and eye-catching.
Are oval cut lab grown diamonds certified by IGI or GIA? +
Yes. Oval cut lab grown diamonds are graded and certified by respected laboratories such
as IGI and GIA. Each certificate includes full details of cut, colour, clarity, carat
weight, proportions, and growth method.
Are oval cut lab grown diamonds suitable for engagement rings? +
Absolutely. The elongated shape of an oval diamond enhances finger appearance, provides
excellent brilliance, and pairs beautifully with solitaire, halo, three-stone, and modern
minimal settings, making it one of the most popular choices for engagement rings.
Do oval cut lab grown diamonds show colour more than round diamonds? +
Oval diamonds can reveal colour slightly more toward their pointed ends due to their
elongated shape. Choosing a colour grade that aligns with your preference ensures a bright,
clean appearance from every angle.
Why are oval cut lab grown diamonds considered good value? +
Oval cut lab grown diamonds often appear larger than their carat weight, offer brilliant
light performance, and provide excellent value. Many buyers choose them for their elegance,
modern appeal, and strong visual presence within their budget.
