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 LG849618156 or 849618156. Listed at 7 retailers as of October 30, 2026, with prices from £105 to £680, a £575 spread on the same certified stone. Michael Trio lists it at £680. 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.
