About this 0.78ct lab-grown princess diamond

This 0.78ct 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 LG831629014 or 831629014. Listed at 26 retailers as of October 30, 2026, with prices from £199 to £1,048, a £849 spread on the same certified stone. Reve Diamonds lists it at £1,048. 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.
