About this 0.73ct lab-grown round diamond

This 0.73ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG787661312 or 787661312. Listed at 21 retailers as of November 1, 2026, with prices from £153 to £910, a £757 spread on the same certified stone. Reve Diamonds lists it at £910. 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.
