This 1.25ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG743504688 or 743504688. Listed at 24 retailers as of October 30, 2026, with prices from $348 to $3,260, a $2,912 spread on the same certified stone. Brilliant Earth lists it at $3,260. 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.
