About this 0.99ct lab-grown cushion diamond

This 0.99ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG648446369 or 648446369. Listed at 16 retailers as of October 29, 2026, with prices from £240 to £1,885, a £1,645 spread on the same certified stone. Do Amore Diamonds lists it at £1,885. 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.
