About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant 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 LG725510975 or 725510975. Listed at 16 retailers as of November 4, 2026, with prices from $207 to $1,199, a $992 spread on the same certified stone. MOH London lists it at $1,199. 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.
