About this 1.05ct lab-grown princess diamond

This 1.05ct 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 LG844684015 or 844684015. Listed at 13 retailers as of November 4, 2026, with prices from £127 to £659, a £532 spread on the same certified stone. MOH London lists it at £659. 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.
