About this 1.16ct lab-grown radiant diamond

This 1.16ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG600368290 or 600368290. Listed at 12 retailers as of October 28, 2026, with prices from $378 to $1,001, a $623 spread on the same certified stone. MOH London lists it at $1,001. 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.
