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 LG764629934 or 764629934. Listed at 5 retailers as of October 28, 2026, with prices from $245 to $850, a $605 spread on the same certified stone. MOH London lists it at $850. 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.
