About this 0.54ct lab-grown asscher diamond

This 0.54ct lab-grown asscher 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 LG818658660 or 818658660. Listed at 18 retailers as of October 30, 2026, with prices from £228 to £1,064, a £836 spread on the same certified stone. Reve Diamonds lists it at £1,064. 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.
