About this 1.25ct lab-grown princess diamond

This 1.25ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG801627865 or 801627865. Listed at 10 retailers as of November 1, 2026, with prices from £262 to £1,095, a £833 spread on the same certified stone. Brilliant Earth lists it at £1,095. 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.
