About this 0.73ct lab-grown cushion diamond

This 0.73ct lab-grown cushion sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG722509316 or 722509316. Listed at 21 retailers as of November 4, 2026, with prices from £214 to £1,025, a £811 spread on the same certified stone. Reve Diamonds lists it at £1,025. 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.
