About this 0.55ct lab-grown asscher diamond

This 0.55ct 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 LG818663257 or 818663257. Listed at 18 retailers as of November 1, 2026, with prices from £231 to £1,074, a £844 spread on the same certified stone. Reve Diamonds lists it at £1,074. 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.
