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 LG793604431 or 793604431. Listed at 20 retailers as of October 25, 2026, with prices from £131 to £853, a £722 spread on the same certified stone. Flawless Fine Jewelry lists it at £853. 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.
