About this 0.9ct lab-grown cushion diamond

This 0.9ct 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 LG806627570 or 806627570. Listed at 14 retailers as of November 4, 2026, with prices from £279 to £2,214, a £1,935 spread on the same certified stone. Do Amore Diamonds lists it at £2,214. 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.
