About this 0.81ct lab-grown cushion diamond

This 0.81ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513724 or 756513724. Listed at 14 retailers as of November 1, 2026, with prices from £193 to £2,229, a £2,036 spread on the same certified stone. Do Amore Diamonds lists it at £2,229. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
