About this 0.37ct lab-grown radiant diamond

This 0.37ct lab-grown radiant sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG660482887 or 660482887. Listed at 18 retailers as of October 25, 2026, with prices from £123 to £788, a £665 spread on the same certified stone. MOH London lists it at £788. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
