About this 1.05ct lab-grown princess diamond

This 1.05ct lab-grown princess sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG706560475 or 706560475. Listed at 7 retailers as of October 29, 2026, with prices from £257 to £693, a £435 spread on the same certified stone. MOH London lists it at £693. 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.
