1 Carat Marquise Lab Grown Diamonds – Regal Silhouette, Brilliant Sparkle & Ethical Luxury
A 1 carat marquise lab grown diamond is admired for its elongated, royal-inspired shape and exceptional brilliance.

At Variation, every 1 carat marquise lab grown diamond is created using advanced CVD and HPHT technology and certified by IGI, ensuring superior symmetry, clarity, and ethical craftsmanship.
Elegant, glamorous, and eye-catching — a 1 carat marquise diamond is perfect for jewellery that stands out with regal sophistication.
