About this 1.24ct lab-grown round diamond

This 1.24ct lab-grown round sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG706553139 or 706553139. Listed at 13 retailers as of November 2, 2026, with prices from $304 to $1,575, a $1,270 spread on the same certified stone. MOH London lists it at $1,575. 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.
