About this 0.55ct lab-grown round diamond

This 0.55ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG801699911 or 801699911. Listed at 19 retailers as of October 29, 2026, with prices from £143 to £969, a £825 spread on the same certified stone. Do Amore Diamonds lists it at £969. 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.
