About this 1.3ct lab-grown radiant diamond

This 1.3ct 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 LG831604041 or 831604041. Listed at 14 retailers as of November 1, 2026, with prices from $751 to $6,132, a $5,381 spread on the same certified stone. Brilliant Earth lists it at $6,132. 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.
