About this 0.81ct lab-grown cushion diamond

This 0.81ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG649432166 or 649432166. Listed at 21 retailers as of October 30, 2026, with prices from £264 to £2,097, a £1,833 spread on the same certified stone. Do Amore Diamonds lists it at £2,097. 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.
