About this 0.49ct lab-grown radiant diamond

This 0.49ct 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 LG808616344 or 808616344. Listed at 13 retailers as of October 30, 2026, with prices from £125 to £741, a £616 spread on the same certified stone. Michael Trio lists it at £741. 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.
