About this 1.53ct lab-grown princess diamond

This 1.53ct 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 very-good cut grade and certified by IGI LG574340056 or 574340056. Listed at 7 retailers as of October 29, 2026, with prices from £239 to £831, a £592 spread on the same certified stone. MOH London lists it at £831. 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.
