Marquise Cut Lab Diamond Engagement Rings
Heritage & Co.'s marquise cut lab diamond engagement rings are set in solid 18K gold with IGI-certified D/VVS1 lab-grown diamonds. Part of our luxury Claritas and Insignia collections, marquise lab diamond rings start from R39,995 — offering the distinctive elongated silhouette of a marquise cut in a certified, ethically sourced stone.
Lab-grown diamonds are real diamonds — same hardness, same chemical composition, same optical properties — with full IGI certification. Our marquise lab diamond rings are made to order in South Africa, with free delivery and a 20-year warranty on every purchase.
Certified Stones
Every centre stone is independently certified and individually selected for proportion, symmetry, and light performance. We do not sell uncertified stones.
Precious Metals Only. No Exceptions.
Every engagement ring is crafted in solid gold or platinum. We do not use sterling silver, plated metals, or vermeil for rings intended to last a lifetime.
Engineered for Lifetime Wear
Reinforced prong settings, balanced proportions, and finishes selected for long term durability. These rings are built for real life, not just the proposal.
We believe customers deserve to understand exactly what they’re buying — from stone certification to metal composition and finishing thickness.
