Frequently Asked Questions
What is a round cut lab grown diamond? +
A round cut lab grown diamond is a perfectly circular diamond with a precise facet pattern
designed to maximise light return and brilliance. It is created in a controlled laboratory
using advanced technology, then cut and polished to the same standards as a mined round
brilliant diamond.
Are round cut lab grown diamonds real diamonds? +
Yes. Round cut lab grown diamonds are 100% real diamonds. They have the same chemical
composition, hardness, and optical performance as mined diamonds and are made of pure
crystalline carbon. They are graded by the same international laboratories using the
same criteria and scales.
Why is the round cut so popular for lab grown diamonds? +
The round brilliant cut is engineered to optimise light performance, giving exceptional
brightness and fire when well cut. It is versatile, timeless, and works beautifully in
almost any style, which is why many people choose round cut lab grown diamonds for
engagement rings, stud earrings, and classic fine jewellery.
What should I focus on in the 4Cs for a round cut lab grown diamond? +
For round cut lab grown diamonds, cut quality is the most important factor because it
directly affects brilliance and light return. After cut, consider colour, clarity, and
carat weight according to your priorities and budget, aiming for a balanced combination
that looks bright and refined in natural light.
Does cut grade really make a difference for round cut lab grown diamonds? +
Yes. Even with the same carat weight, a better cut grade can make a round cut lab grown
diamond appear more lively and visually impressive. Well-aligned facets, ideal proportions,
and symmetry allow more light to reflect internally and return through the top of the stone.
Do round cut lab grown diamonds look different from mined round diamonds? +
To the eye, a round cut lab grown diamond and a round cut mined diamond with similar
specifications will look the same in terms of brightness, fire, and overall appearance.
Gemological instruments and report inscriptions, not appearance alone, are used to identify
whether a diamond is lab grown or mined.
Are round cut lab grown diamonds certified by IGI or GIA? +
Yes. Round cut lab grown diamonds are graded and certified by trusted laboratories such as
IGI and GIA. Each certified stone comes with a detailed grading report outlining its cut,
colour, clarity, carat weight, proportions, and growth method.
What is the ideal ratio for a round cut lab grown diamond? +
For round cut lab grown diamonds, the ideal length-to-width ratio is very close to 1.00,
indicating a true circle. Small deviations are normal, but a ratio near 1.00 helps the
diamond look balanced and symmetrical when viewed from the top.
Are round cut lab grown diamonds suitable for everyday wear? +
Yes. Lab grown diamonds, including round cut stones, rank 10 on the Mohs hardness scale,
exactly like mined diamonds. This makes them highly durable and suitable for everyday
wear in pieces such as engagement rings, bands, and daily jewellery that is worn often.
Do round cut lab grown diamonds offer better value compared to mined diamonds? +
In many cases, round cut lab grown diamonds allow you to choose a larger size or higher
quality within the same budget compared to a comparable mined diamond. This value, combined
with transparent sourcing and controlled origin, is why many modern buyers prefer lab grown
options.
