About this 0.55ct lab-grown oval diamond

This 0.55ct lab-grown oval sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG823694991 or 823694991. Listed at 21 retailers as of October 29, 2026, with prices from £121 to £800, a £680 spread on the same certified stone. Reve Diamonds lists it at £800. 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.
