This 0.89ct lab-grown cushion sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG666410881 or 666410881. Listed at 17 retailers as of November 1, 2026, with prices from £174 to £1,299, a £1,125 spread on the same certified stone. Do Amore Diamonds lists it at £1,299. 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.
