About this 0.73ct lab-grown marquise diamond

This 0.73ct lab-grown marquise 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 LG733547723 or 733547723. Listed at 24 retailers as of November 1, 2026, with prices from £171 to £957, a £787 spread on the same certified stone. Reve Diamonds lists it at £957. 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.
