About this 0.52ct lab-grown round diamond

This 0.52ct lab-grown round sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG791650132 or 791650132. Listed at 11 retailers as of November 1, 2026, with prices from £143 to £1,028, a £885 spread on the same certified stone. Kay Jewelers lists it at £1,028. 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.
