About this 0.55ct lab-grown round diamond

This 0.55ct 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 LG800685489 or 800685489. Listed at 10 retailers as of October 30, 2026, with prices from £112 to £925, a £813 spread on the same certified stone. Do Amore Diamonds lists it at £925. 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.
