About this 1.59ct lab-grown princess diamond

This 1.59ct lab-grown princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG476162152 or 476162152. Listed at 7 retailers as of November 1, 2026, with prices from £399 to £1,061, a £662 spread on the same certified stone. MOH London lists it at £1,061. 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.
