About this 0.94ct lab-grown round diamond

This 0.94ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840622051 or 840622051. Listed at 21 retailers as of October 28, 2026, with prices from £120 to £1,008, a £889 spread on the same certified stone. Brilliant Earth lists it at £1,008. 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.
