About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG827605366 or 827605366. Listed at 19 retailers as of October 29, 2026, with prices from £138 to £911, a £772 spread on the same certified stone. Do Amore Diamonds lists it at £911. 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.
