This 1.56ct lab-grown radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG649406101 or 649406101. Listed at 8 retailers as of November 1, 2026, with prices from $369 to $1,275, a $906 spread on the same certified stone. MOH London lists it at $1,275. 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.
