This 1.45ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG633490188 or 633490188. Listed at 20 retailers as of October 26, 2026, with prices from £166 to £825, a £659 spread on the same certified stone. MOH London lists it at £825. 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.
