About this 0.37ct lab-grown radiant diamond

This 0.37ct lab-grown radiant sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG657468860 or 657468860. Listed at 19 retailers as of October 31, 2026, with prices from £61 to £737, a £676 spread on the same certified stone. MOH London lists it at £737. 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.
