About this 1.24ct lab-grown princess diamond

This 1.24ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG791627755 or 791627755. Listed at 3 retailers as of November 5, 2026, with prices from £423 to £560, a £137 spread on the same certified stone. The Diamond Guys lists it at £560. 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.
