About this 0.91ct lab-grown princess diamond

This 0.91ct lab-grown princess 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 LG782652944 or 782652944. Listed at 7 retailers as of October 29, 2026, with prices from £328 to £1,179, a £852 spread on the same certified stone. Brilliant Earth lists it at £1,179. 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.
