What is a Lab grown Marquise Engagement ring?

A marquise cut, also known as the 'navette' shape, is an elongated oval with pointed ends, designed to maximise its visual impact per carat. This elegant cut provides a unique and timeless appeal, making it a popular choice for engagement rings. Lab-grown diamonds are created using advanced technology that replicates the natural diamond formation process in a controlled environment. While natural diamonds take millions of years to develop within the Earth's crust, lab-grown diamonds can be formed in a matter of weeks. These diamonds possess the same chemical and physical properties as mined diamonds but are significantly more affordable, making them an excellent choice for those seeking luxury at a lower cost.

What should I look for when buying a marquise diamond ring?

When selecting a lab-grown marquise diamond engagement ring, prioritise the cut quality, as the marquise cut is a brilliant-cut diamond, meaning a high-grade cut enhances its sparkle and brilliance. Clarity is also crucial, as the elongated facets of the marquise cut can sometimes reveal inclusions more easily than other cuts. Opting for a high clarity grade ensures a flawless, eye-clean appearance. The ideal diamond colour depends on your choice of metal. If selecting platinum or white gold, aim for a near-colourless grade to maintain a crisp, radiant look. Additionally, marquise diamonds naturally appear larger than their actual carat weight, which is an advantage, but practicality should be considered when choosing the size—especially if opting for a halo setting, which can further amplify its visual impact.
