About this 0.43ct lab-grown princess diamond

This 0.43ct lab-grown princess 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 LG819622558 or 819622558. Listed at 24 retailers as of October 29, 2026, with prices from £190 to £1,056, a £866 spread on the same certified stone. MOH London lists it at £1,056. 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.
