Round Cut Engagement Rings | Lab Grown Diamond | IGI

The round brilliant is the most popular diamond shape in the world and the only one cut to a mathematically optimised formula for light return. Its 57 or 58 facets are arranged to send light back through the top of the stone rather than leaking it out of the sides, which is why a round reads brighter than any other shape at the same carat weight. Ronora lab grown diamonds are real CVD stones, VVS clarity, D-E-F colorless; this collection also includes moissanite rings, noted on each product page.

Why does the round cut sparkle more?

Because it is the only shape where the proportions are standardised and graded. Every other shape is cut to the cutter's judgement. In a round, depth, table and crown angle are measured against a known ideal, so brilliance is predictable rather than variable.

What does a round cost compared to other shapes?

Round is usually the most expensive shape per carat, because cutting one wastes more of the original crystal than a fancy shape does. Grown in a lab, that premium is far smaller than it is for mined stones.

Frequently asked questions

Which setting suits a round best? A solitaire shows the cut most honestly. A hidden halo makes the stone read larger without adding a visible ring of smaller diamonds.

Is a round the right choice for a smaller carat? Yes. Round holds its brilliance at smaller sizes better than step cuts, which can look flat under half a carat.
