About this 1.27ct lab-grown princess diamond

This 1.27ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG669417009 or 669417009. Listed at 20 retailers as of October 27, 2026, with prices from £180 to £1,016, a £836 spread on the same certified stone. Brilliant Earth lists it at £1,016. 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.
