About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG837681161 or 837681161. Listed at 14 retailers as of November 1, 2026, with prices from £184 to £870, a £686 spread on the same certified stone. Reve Diamonds lists it at £870. 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.
