About this 0.53ct lab-grown round diamond

This 0.53ct 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 LG726536418 or 726536418. Listed at 24 retailers as of October 29, 2026, with prices from £99 to £926, a £827 spread on the same certified stone. MOH London lists it at £926. 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.
