About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG689560584 or 689560584. Listed at 18 retailers as of October 26, 2026, with prices from $150 to $871, a $721 spread on the same certified stone. MOH London lists it at $871. 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.
