Laboratory-grown diamonds are real diamonds. They are grown in a laboratory that replicates the same conditions under which diamonds form naturally, extreme heat, extreme pressure, and pure carbon. The end result is a stone that is chemically, physically, and optically identical to a mined diamond. Not similar. Identical.

No. A laboratory-grown diamond and a mined diamond are structurally the same stone. Even a trained gemologist examining it under a professional loupe cannot tell them apart. The only instruments that can detect the difference are highly specialised laboratory machines that read microscopic variations in growth patterns, the kind used by professional laboratories.

No. regardless of its origin, whether its laboratory-grown diamond or mined diamond it scores 10 on the Mohs scale, the highest hardness rating of any material on earth. It will not cloud, fade or change its color over time. The diamond you buy today will look exactly the same decades from now.

Yes. Every Luminique diamond comes with an independent grading certificate from renowned laboratories, the same institutions that certify mined diamonds globally. All gold used in our jewellery is BIS Hallmarked and carries a unique HUID, which confirms the purity of the metal.

Yes. Luminique offers 85% Lifetime Buyback and 100% Lifetime Exchange on all laboratory-grown diamonds. The buyback and exchange values are calculated against the current market selling price at the time of the transaction. Note that making charges, GST, certification costs, and any discounts applied at the time of purchase are not included in the buyback or exchange calculation.

The price difference comes from the supply chain, not the quality. A mined diamond passes through extraction operations, multiple intermediaries, and years of logistics before it reaches a jeweller. A laboratory-grown diamond does not. That reduction in cost is reflected in the price. The stone itself, its hardness, brilliance, and grading, is the same.

The term synthetic is technically a misnomer in this context. Synthetic typically refers to imitations, materials like cubic zirconia or moissanite that looks like diamonds but are not. A laboratory-grown diamonds is not an imitation. It is made of the same carbon crystal structure as a mined diamond. Under 2026 BIS standards, laboratory-grown diamonds are officially classified and recognised as diamonds.
