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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG787629527 or 787629527. Listed at 20 retailers as of October 29, 2026, with prices from £116 to £783, a £667 spread on the same certified stone. Reve Diamonds lists it at £783. 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.
