About this 1.01ct lab-grown princess diamond

This 1.01ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG835631229 or 835631229. Listed at 9 retailers as of November 4, 2026, with prices from £108 to £625, a £517 spread on the same certified stone. MOH London lists it at £625. 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.
