About this 2.58ct lab-grown radiant diamond

This 2.58ct lab-grown radiant sits in the two to three carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818684462 or 818684462. Listed at 11 retailers as of October 30, 2026, with prices from $2,125 to $8,590, a $6,465 spread on the same certified stone. Brilliant Earth lists it at $8,590. 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.
