Lab Grown Diamonds

A lab grown diamond is a real diamond — chemically, optically and physically identical to a mined diamond — created in a controlled laboratory environment using HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) technology. They are composed of pure crystallized carbon with the same hardness (10 on the Mohs scale), refractive index, and brilliance as natural diamonds. The only difference is their origin.

Yes. Every lab grown diamond in our inventory is independently certified by IGI (International Gemological Institute) or GIA (Gemological Institute of America). Each certificate documents the diamond's carat weight, color, clarity, cut, and proportions — the same grading standards used for mined diamonds. Learn more in our certification guide.

Lab grown diamonds typically cost 60–80% less than natural diamonds of comparable quality. For example, a 1-carat round brilliant with excellent cut, G color, and VS1 clarity might cost $5,000–$7,000 as a natural diamond, but only $1,000–$2,000 as lab grown. The savings increase significantly with larger carat weights.

No — not with the naked eye, and not even under a standard jeweler's loupe. Lab grown diamonds have the same optical properties (fire, brilliance, scintillation) as mined diamonds. Only specialized laboratory equipment can detect the subtle growth patterns that distinguish them. Every lab grown diamond is laser-inscribed on the girdle with its certificate number for identification.

Absolutely. Lab grown diamonds are perfect for engagement rings — they offer the same beauty and durability as natural diamonds at a fraction of the cost. Every diamond can be set in any of our engagement ring settings. Use our Design Your Own Ring tool to pair your lab grown diamond with the setting of your choice.
