Lab-grown diamonds are real diamonds created using advanced technology that replicates the natural formation process of diamonds deep within the Earth. The result is a diamond that is chemically, physically, and optically identical to a mined diamond. The only difference is origin — one comes from the Earth, the other from a lab.

At NYX Jewel, we use only premium-quality lab-grown diamonds that meet strict ethical and environmental standards, ensuring your jewelry shines with both brilliance and conscience.

Yes! Lab-grown diamonds are 100% real diamonds — not simulants like cubic zirconia or moissanite. They have the same sparkle, durability, and hardness as natural diamonds. Even professional gemologists require specialized equipment to tell them apart.

Our lab-grown diamonds are certified by reputable gemological laboratories such as IGI or GIA, confirming their authenticity, cut, clarity, and color.

Absolutely. Every diamond you purchase from NYX Jewel comes with an independent grading certificate from a trusted gemological institute. This document details your diamond’s cut, clarity, color, and carat weight — giving you confidence and transparency in every purchase.

We also include a certificate of authenticity from NYX Jewel verifying your diamond is ethically lab-grown and sustainably produced.
