This 1.46ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG671437240 or 671437240. Listed at 2 retailers as of October 30, 2026, with prices from $1,340 to $2,920, a $1,580 spread on the same certified stone. Kay Jewelers lists it at $2,920. 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.
