At GRWN, we grow our diamonds above ground using advanced technology that replicates the natural diamond-growing process. Inside a high-temperature, high-pressure chamber, a tiny diamond seed transforms into a brilliant crystal as layers of pure carbon accumulate atom by atom.

This method- known as Chemical Vapor Deposition (CVD)- creates diamonds that are chemically, physically, and optically identical to those mined from the earth. The result: stunning diamonds with exceptional beauty, grown sustainably and responsibly.

At GRWN, we believe that trust and transparency are non-negotiable. That’s why all of our diamonds come with grading reports from the world’s most respected gemological laboratories:

GIA (Gemological Institute of America):

• Recognized globally for strict grading standards, GIA reports provide a comprehensive assessment of your diamond’s quality, including the 4Cs—cut, color, clarity, and carat weight.

GCAL (Gem Certification & Assurance Lab):

• GCAL offers not only grading reports but also advanced verification services such as light performance analysis and unique diamond fingerprinting for security and authenticity.

These laboratory reports guarantee that every GRWN diamond meets the highest standards of quality and integrity, giving you the assurance that your diamond is as exceptional as it is beautiful.
