About this 1.42ct lab-grown princess diamond

This 1.42ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG706531150 or 706531150. Listed at 7 retailers as of November 4, 2026, with prices from £310 to £829, a £520 spread on the same certified stone. MOH London lists it at £829. 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.
