This 1.31ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG593372670 or 593372670. Listed at 5 retailers as of November 3, 2026, with prices from $436 to $1,620, a $1,184 spread on the same certified stone. MOH London lists it at $1,620. 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.
