This 1.37ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG451080467 or 451080467. Listed at 2 retailers as of November 4, 2026, with prices from $795 to $1,529, a $734 spread on the same certified stone. Taylor and Hart lists it at $1,529. 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.
