About this 0.96ct lab-grown cushion diamond

This 0.96ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817618392 or 817618392. Listed at 7 retailers as of October 29, 2026, with prices from £337 to £1,224, a £887 spread on the same certified stone. Brilliant Earth lists it at £1,224. 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.
