This 1.28ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG605341056 or 605341056. Listed at 13 retailers as of October 30, 2026, with prices from $478 to $2,327, a $1,849 spread on the same certified stone. Do Amore Diamonds lists it at $2,327. 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.
