About this 1.28ct lab-grown princess diamond

This 1.28ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG642498193 or 642498193. Listed at 13 retailers as of October 27, 2026, with prices from £203 to £1,067, a £864 spread on the same certified stone. Brilliant Earth lists it at £1,067. 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.
