Frequently Asked Questions

Yes. Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. They are graded by IGI using the same 4Cs standards. Even expert gemologists cannot tell the difference without specialized equipment.

IGI (International Gemological Institute) independently grades and certifies each diamond's cut, color, clarity, and carat weight. Every VELUNIQ diamond 0.50 carat and larger comes with an official IGI grading report.

Lab-grown diamonds are typically 40–60% less expensive than mined diamonds of equal quality. This is because they bypass the massive costs associated with mining, shipping, and cartel-controlled supply chains.

Diamond values vary over time. We recommend purchasing jewelry for the joy of wearing the piece, not as a financial investment. That said, lab-grown diamonds carry the same brilliance, hardness, and beauty as mined diamonds.
