Lab-Grown Blue Diamonds

Lab-grown blue diamonds reproduce the stunning blue hues of natural blue diamonds — achieved by introducing boron during the growth process, the same element that colours natural blue diamonds. The result is a physically identical gemstone at a fraction of the natural price.

Natural blue diamonds are among the most expensive gemstones on earth, with prices starting at £30,000+ per carat for faint blues. Lab-grown blue diamonds make this extraordinary colour accessible, with certified stones available at 90–95% less.

Every lab-grown blue diamond at MOH London is independently certified by IGI, with colour graded on the standard fancy colour intensity scale.
