About this 0.81ct lab-grown round diamond

This 0.81ct lab-grown round 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 LG756552064 or 756552064. Listed at 22 retailers as of October 28, 2026, with prices from £134 to £845, a £711 spread on the same certified stone. Reve Diamonds lists it at £845. 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.
