About this 0.68ct lab-grown cushion diamond

This 0.68ct 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 LG804603872 or 804603872. Listed at 13 retailers as of November 3, 2026, with prices from £274 to £1,985, a £1,711 spread on the same certified stone. Do Amore Diamonds lists it at £1,985. 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.
