About this 1.35ct lab-grown princess diamond

This 1.35ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605342090 or 605342090. Listed at 10 retailers as of November 4, 2026, with prices from £170 to £829, a £659 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.
