This 1.69ct lab-grown princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG539226978 or 539226978. Listed at 16 retailers as of October 26, 2026, with prices from £153 to £892, a £739 spread on the same certified stone. MOH London lists it at £892. 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.
