About this 0.4ct lab-grown princess diamond

This 0.4ct 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 LG831629013 or 831629013. Listed at 18 retailers as of October 29, 2026, with prices from €214 to €1,187, a €973 spread on the same certified stone. MOH London lists it at €1,187. 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.
