About this 1.2ct lab-grown radiant diamond

This 1.2ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG801646169 or 801646169. Listed at 4 retailers as of November 3, 2026, with prices from $691 to $1,230, a $539 spread on the same certified stone. Jared lists it at $1,230. 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.
