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 LG656403261 or 656403261. Listed at 15 retailers as of October 30, 2026, with prices from £184 to £1,881, a £1,697 spread on the same certified stone. Do Amore Diamonds lists it at £1,881. 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.
