About this 1.23ct lab-grown princess diamond

This 1.23ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG631466952 or 631466952. Listed at 16 retailers as of November 4, 2026, with prices from £127 to £827, a £700 spread on the same certified stone. Flawless Fine Jewelry lists it at £827. 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.
