About this 0.41ct lab-grown radiant diamond

This 0.41ct 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 LG657416910 or 657416910. Listed at 22 retailers as of October 25, 2026, with prices from £77 to £845, a £769 spread on the same certified stone. MOH London lists it at £845. 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.
