A lab-grown diamond is physically, chemically, and optically identical to a natural diamond — the only difference is its origin. Created using advanced technology that replicates the conditions under which natural diamonds form, lab-grown diamonds offer the same brilliance, fire, and durability at 60–80% less cost.
A lab-grown diamond is physically, chemically, and optically identical to a natural diamond — the only difference is its origin. Created using advanced technology that replicates the conditions under which natural diamonds form, lab-grown diamonds offer the same brilliance, fire, and durability at 60–80% less cost.
For engagement rings, this means you can choose a significantly larger or higher-quality centre stone within the same budget. A client who might select a 0.7ct natural diamond can often afford a 1.5ct lab-grown diamond of equivalent quality — a dramatic visual difference on the hand.
Every lab-grown diamond at MOH London is independently certified by IGI or GIA. We apply the same selection standards as our natural diamonds: excellent or very good cut quality, minimal fluorescence, and visual inspection beyond the certificate. Our gemmologists can help you navigate the options and find the perfect stone for your ring.
