About this 0.55ct lab-grown cushion diamond

This 0.55ct lab-grown cushion 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 LG739528652 or 739528652. Listed at 23 retailers as of November 1, 2026, with prices from £188 to £1,617, a £1,429 spread on the same certified stone. Do Amore Diamonds lists it at £1,617. 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.
