This 1.22ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836630774 or 836630774. Listed at 17 retailers as of October 25, 2026, with prices from £172 to £948, a £776 spread on the same certified stone. Brilliant Earth lists it at £948. 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.
