Collection: Marquise Cut Lab Grown Diamond Rings

A marquise cut diamond features an elongated, boat-shaped outline with pointed ends on both sides. When lab-grown, the diamond is created in a controlled environment using either HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) technology producing a stone chemically and physically identical to a mined diamond. Luxurian Jewels offers marquise cut lab-grown diamonds set in rings crafted from gold and platinum.

Yes lab-grown diamonds are 100% real diamonds. They have the same chemical composition (pure carbon), the same crystal structure, the same hardness (10 on the Mohs scale), and the same optical brilliance as earth-mined diamonds. The only difference is their origin. The Gemological Institute of America (GIA) and IGI certify lab-grown diamonds using the same 4Cs grading cut, color, clarity, and carat as natural diamonds.

The marquise cut creates a visual elongation effect on the finger, making fingers appear slimmer and longer. Its large surface area also makes the stone appear bigger than other cuts of the same carat weight giving excellent value for money. The pointed ends give it a distinctive, vintage-inspired look that stands out from round brilliants. It pairs beautifully with solitaire, halo, and side-stone settings.

Lab-grown marquise diamonds typically cost 60–80% less than equivalent mined diamonds. At Luxurian Jewels, prices vary based on carat weight, metal type (gold or platinum), and ring design. The elongated marquise shape also gives maximum visual size per carat, making it one of the most cost-effective fancy cuts.

Yes. Lab-grown diamonds from reputable jewellers including Luxurian Jewels come with grading certificates from recognised labs such as IGI (International Gemological Institute) or GIA. The certificate confirms the diamond's cut, colour, clarity, and carat weight. Always request the certificate when purchasing — it is your guarantee of quality and authenticity.

Marquise cut lab-grown diamond rings at Luxurian Jewels are typically available in 14K or 18K yellow gold, white gold, rose gold, and platinum. White gold and platinum are popular choices as they enhance the diamond's brilliance and complement the elongated marquise shape. Rose gold settings give a vintage, romantic feel. The metal choice also affects the overall price of the ring.

The pointed tips of a marquise cut are its most vulnerable points — they can chip if knocked hard. It's recommended to choose a setting with prongs or a bezel that protects both ends. For cleaning, use warm water with a drop of mild dish soap and a soft toothbrush. Avoid harsh chemicals and ultrasonic cleaners unless recommended by a jeweller. Remove the ring during heavy physical activity or sports.
