About this 0.73ct lab-grown cushion diamond

This 0.73ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG742508043 or 742508043. Listed at 11 retailers as of October 31, 2026, with prices from £229 to £852, a £623 spread on the same certified stone. Blue Nile lists it at £852. 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.
