Radiant Cut Lab Grown Diamonds – Your Questions Answered
What is a radiant cut lab grown diamond?
+
A radiant cut lab grown diamond is a rectangular or square-shaped diamond with trimmed corners and 70 facets that maximise sparkle. It combines the brilliance of a round cut with the clean lines of an emerald cut, offering a bold yet elegant appearance.
How does a radiant cut differ from an emerald cut?
+
While both shapes share a similar outline, emerald cuts use step-cut facets that create a hall-of-mirrors look, whereas radiant cuts use brilliant-cut facets, delivering significantly more sparkle, fire, and edge-to-edge scintillation.
Do radiant cut lab grown diamonds sparkle a lot?
+
Yes. Radiant cuts are known for their intense, vibrant sparkle thanks to their brilliant-cut facet pattern. They show bursts of light similar to round diamonds but with a more geometric shape that enhances modern design styles.
Are radiant cut lab grown diamonds good for engagement rings?
+
Absolutely. Radiant cut lab grown diamonds are a popular choice for engagement rings due to their high brilliance, durability, and flattering shape. They look stunning in solitaire, halo, three-stone, and hidden halo designs.
Do radiant cuts look bigger than other shapes of the same carat weight?
+
Radiant cut diamonds often appear larger because of their elongated shape (in rectangular versions) and brilliant facet pattern. The trimmed corners also enhance the visible face-up area, making the diamond look more substantial.
What is the ideal length-to-width ratio for radiant cut lab grown diamonds?
+
Radiant cuts offer flexibility. For rectangular radiant diamonds, ratios between 1.20–1.35 are most popular. For square radiants, a ratio close to 1.00 provides a symmetrical look. The right choice depends on your personal preference.
What 4Cs matter most for radiant cut lab grown diamonds?
+
Cut and colour matter the most. The brilliant facet pattern hides inclusions well, so VS–SI clarity can still look clean. Colour is more visible in radiant cuts, so many buyers prefer D–H grades for a brighter, whiter appearance.
Do radiant cut lab grown diamonds show a bow-tie effect?
+
Radiant cuts may show a mild bow-tie effect depending on proportions, but a well-cut radiant diamond will minimise it. Proper facet alignment and depth percentages reduce shadows and maximise light performance.
Which ring settings suit radiant cut lab grown diamonds?
+
Radiant cuts look stunning in solitaire prong settings, halos, hidden halos, vintage frames, and three-stone rings. Their strong sparkle pairs beautifully with side stones like trapezoids, pears, trillions, or tapered baguettes.
Are radiant cut lab grown diamonds certified?
+
Yes. Radiant cut lab grown diamonds are graded by recognized laboratories such as IGI and GIA. Certificates include details on cut, colour, clarity, carat weight, and the diamond’s lab-grown origin.
