This 1.31ct 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 LG593372637 or 593372637. Listed at 6 retailers as of November 1, 2026, with prices from £298 to £790, a £492 spread on the same certified stone. MOH London lists it at £790. 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.
