About this 1ct lab-grown princess diamond

This 1ct lab-grown princess sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG845669375 or 845669375. Listed at 14 retailers as of October 26, 2026, with prices from €131 to €760, a €629 spread on the same certified stone. MOH London lists it at €760. 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.
