About this 0.55ct lab-grown asscher diamond

This 0.55ct lab-grown asscher 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 LG692566885 or 692566885. Listed at 24 retailers as of October 30, 2026, with prices from £139 to £899, a £760 spread on the same certified stone. Flawless Fine Jewelry lists it at £899. 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.
