Marquise Cut Engagement Rings | Lab Grown Diamond | IGI

The marquise cut covers more finger than any other diamond shape at the same carat weight. That is not marketing, it is geometry: the elongated boat shape spreads the stone's weight across the longest possible footprint, so a marquise reads visibly larger than a round of identical weight and identical price.

Every marquise cut lab grown diamond engagement ring here is made to order in our Surat studio. The centre stones are Real CVD Lab-Grown Diamonds in VVS clarity and the D-E-F Colorless range, grown using Chemical Vapor Deposition technology. The marquise has two pointed tips where light escapes most easily, which is exactly why we do not set anything below VVS in this shape.

Long associated with Art Deco and vintage design, the marquise has returned as the shape people choose when they do not want the ring everyone else has. Available in solitaire, halo, three stone, bezel, curved and eternity settings, in 10K, 14K and 18K solid gold across white, yellow and rose, plus platinum.

2 Carat Marquise Lab Grown Diamond Engagement Rings

A 2 carat marquise measures roughly 13mm by 6.5mm against a 2 carat round at about 8.1mm across. That extra length is what makes the marquise the most efficient shape in the catalogue for anyone who wants maximum presence per carat.

Set east to west rather than north to south, the same stone reads modern instead of vintage. Every centre stone from 1 carat upward arrives with IGI certification.

Frequently Asked Questions

How much does a lab grown marquise diamond cost?
At Ronora a marquise cut lab grown diamond ring starts at $132 for a curved band and $645 for a certified marquise centre stone. Most of the engagement ring range sits between $720 and $1,500 depending on carat weight, metal and setting.

Can marquise diamonds be lab grown?
Yes. Every marquise in this collection is a Real CVD Lab-Grown Diamond. The shape is achieved through cutting, so it is available in lab grown exactly as it is in mined stones, at a fraction of the price.

Why does a marquise look bigger than other shapes?
Carat measures weight, not size. The marquise spreads that weight across the longest footprint of any cut, so more of the stone faces upward. A 2 carat marquise measures roughly 13mm by 6.5mm while a 2 carat round measures about 8.1mm across.

Are marquise diamonds fragile at the points?
The two tips are the thinnest part of any marquise, which is why we set them protected: in a bezel, under a prong that covers the point, or within a halo. Set properly, a marquise handles daily wear like any other shape, at 10 on the Mohs hardness scale.

What clarity and colour are Ronora's marquise diamonds?
Every marquise we set is VVS clarity in the D-E-F Colorless range. We do not stock lower grades. In a shape with this much visible surface, that consistency matters more than it would in a smaller cut.
