About this 0.91ct lab-grown cushion diamond

This 0.91ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840630025 or 840630025. Listed at 2 retailers as of November 4, 2026, with prices from £617 to £1,284, a £667 spread on the same certified stone. Taylor and Hart lists it at £1,284. 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.
