This 3.07ct lab-grown radiant sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831627725 or 831627725. Listed at 9 retailers as of November 1, 2026, with prices from $1,237 to $3,826, a $2,589 spread on the same certified stone. Taylor and Hart lists it at $3,826. 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.
