About this 1ct lab-grown princess diamond

This 1ct lab-grown princess sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG837659596 or 837659596. Listed at 16 retailers as of October 29, 2026, with prices from £127 to £739, a £612 spread on the same certified stone. MOH London lists it at £739. 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.
